Complete Rebuild: Taskmaster App with Firebase Backend

I understand your frustration with the persistent 403 errors. Let's take a completely different approach by rebuilding your app with Firebase as the backend instead of PHP/MySQL. This will be much more reliable and easier to implement.

Step 1: Set Up Firebase Project

Go to Firebase Console
Click "Add project"
Name it "Taskmaster"
Follow the setup wizard (you can disable Google Analytics if you want)
Once created, click "Continue"

Step 2: Add Firebase to Your Android Project

In Firebase Console, click on the Android icon to add an Android app
Enter your package name: com.example.taskmaster
Register the app
Download the google-services.json file
Place this file in your app directory in Android Studio

Step 3: Update Your Gradle Files

Update your project-level build.gradle:

buildscript {
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:7.0.4'
        classpath 'com.google.gms:google-services:4.3.15'
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

Update your app-level build.gradle:

plugins {
    id 'com.android.application'
    id 'com.google.gms.google-services'
}

android {
    namespace "com.example.taskmaster"
    compileSdk 34

    defaultConfig {
        applicationId "com.example.taskmaster"
        minSdk 21
        targetSdk 34
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    buildFeatures {
        viewBinding true
    }
}

dependencies {
    implementation 'androidx.appcompat:appcompat:1.6.1'
    implementation 'com.google.android.material:material:1.10.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
    
    // Firebase
    implementation platform('com.google.firebase:firebase-bom:32.3.1')
    implementation 'com.google.firebase:firebase-auth'
    implementation 'com.google.firebase:firebase-firestore'
    
    // ViewModel and LiveData
    implementation 'androidx.lifecycle:lifecycle-viewmodel:2.6.2'
    implementation 'androidx.lifecycle:lifecycle-livedata:2.6.2'
    
    // RecyclerView
    implementation 'androidx.recyclerview:recyclerview:1.3.2'
    
    // CircleImageView for profile pictures
    implementation 'de.hdodenhof:circleimageview:3.1.0'
    
    // Testing
    testImplementation 'junit:junit:4.13.2'
    androidTestImplementation 'androidx.test.ext:junit:1.1.5'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.5.1'
}

Step 4: Enable Firebase Authentication

In Firebase Console, go to "Authentication"
Click "Get Started"
Enable "Email/Password" authentication
Save the changes

Step 5: Create Firestore Database

In Firebase Console, go to "Firestore Database"
Click "Create database"
Start in test mode (we'll update security rules later)
Choose a location close to you
Click "Enable"

Step 6: Update Your Model Classes

Create a new User model:

package com.example.taskmaster.model;

public class User {
    private String userId;
    private String username;
    private String email;
    private String fullName;

    public User() {
        // Required empty constructor for Firestore
    }

    public User(String userId, String username, String email, String fullName) {
        this.userId = userId;
        this.username = username;
        this.email = email;
        this.fullName = fullName;
    }

    // Getters and setters
    public String getUserId() {
        return userId;
    }

    public void setUserId(String userId) {
        this.userId = userId;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getFullName() {
        return fullName;
    }

    public void setFullName(String fullName) {
        this.fullName = fullName;
    }
}

Update your Task model:

package com.example.taskmaster.model;

import java.util.Date;

public class Task {
    private String taskId;
    private String userId;
    private String title;
    private String description;
    private Date dueDate;
    private String priority;
    private String category;
    private boolean completed;
    private Date createdAt;

    public Task() {
        // Required empty constructor for Firestore
    }

    // Constructor with all fields
    public Task(String taskId, String userId, String title, String description, 
                Date dueDate, String priority, String category, boolean completed, Date createdAt) {
        this.taskId = taskId;
        this.userId = userId;
        this.title = title;
        this.description = description;
        this.dueDate = dueDate;
        this.priority = priority;
        this.category = category;
        this.completed = completed;
        this.createdAt = createdAt;
    }

    // Getters and setters
    public String getTaskId() {
        return taskId;
    }

    public void setTaskId(String taskId) {
        this.taskId = taskId;
    }

    public String getUserId() {
        return userId;
    }

    public void setUserId(String userId) {
        this.userId = userId;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public Date getDueDate() {
        return dueDate;
    }

    public void setDueDate(Date dueDate) {
        this.dueDate = dueDate;
    }

    public String getPriority() {
        return priority;
    }

    public void setPriority(String priority) {
        this.priority = priority;
    }

    public String getCategory() {
        return category;
    }

    public void setCategory(String category) {
        this.category = category;
    }

    public boolean isCompleted() {
        return completed;
    }

    public void setCompleted(boolean completed) {
        this.completed = completed;
    }

    public Date getCreatedAt() {
        return createdAt;
    }

    public void setCreatedAt(Date createdAt) {
        this.createdAt = createdAt;
    }
}

Step 7: Create Repository Classes

Create UserRepository:

package com.example.taskmaster.repository;

import android.content.Context;
import android.content.SharedPreferences;
import android.util.Log;

import com.google.firebase.auth.FirebaseAuth;
import com.google.firebase.auth.FirebaseUser;
import com.google.firebase.firestore.FirebaseFirestore;
import com.google.gson.Gson;

import com.example.taskmaster.model.User;

import java.util.HashMap;
import java.util.Map;

public class UserRepository {
    private static final String TAG = "UserRepository";
    private static final String PREF_NAME = "TaskmasterPrefs";
    private static final String KEY_USER = "user";
    
    private final Context context;
    private final FirebaseAuth auth;
    private final FirebaseFirestore db;
    private final SharedPreferences sharedPreferences;

    public UserRepository(Context context) {
        this.context = context;
        this.auth = FirebaseAuth.getInstance();
        this.db = FirebaseFirestore.getInstance();
        this.sharedPreferences = context.getSharedPreferences(PREF_NAME, Context.MODE_PRIVATE);
    }

    public interface AuthCallback {
        void onSuccess(User user);
        void onError(String message);
    }

    public void login(String email, String password, final AuthCallback callback) {
        auth.signInWithEmailAndPassword(email, password)
                .addOnCompleteListener(task -> {
                    if (task.isSuccessful()) {
                        FirebaseUser firebaseUser = auth.getCurrentUser();
                        if (firebaseUser != null) {
                            // Get user data from Firestore
                            db.collection("users").document(firebaseUser.getUid())
                                    .get()
                                    .addOnSuccessListener(documentSnapshot -> {
                                        if (documentSnapshot.exists()) {
                                            User user = documentSnapshot.toObject(User.class);
                                            // Save user to SharedPreferences
                                            saveUser(user);
                                            callback.onSuccess(user);
                                        } else {
                                            // Create a basic user if not in Firestore yet
                                            User newUser = new User(
                                                    firebaseUser.getUid(),
                                                    email.split("@")[0], // Simple username from email
                                                    email,
                                                    firebaseUser.getDisplayName() != null ? 
                                                            firebaseUser.getDisplayName() : "User"
                                            );
                                            saveUserToFirestore(newUser, callback);
                                        }
                                    })
                                    .addOnFailureListener(e -> {
                                        Log.e(TAG, "Error getting user data", e);
                                        callback.onError("Error getting user data: " + e.getMessage());
                                    });
                        } else {

                    }
                });

                    }
                });
    }

    private void saveUserToFirestore(User user, AuthCallback callback) {

                                    .addOnSuccessListener(aVoid -> callback.onSuccess("Task deleted successfully"))
                                    .addOnFailureListener(e -> {
                                        Log.e(TAG, "Error deleting task", e);
                                        callback.onError("Error deleting task: " + e.getMessage());
                                    });
                        } else {
                            callback.onError("You don't have permission to delete this task");
                        }
                    } else {
                        callback.onError("Task not found");
                    }
                })
                .addOnFailureListener(e -> {
                    Log.e(TAG, "Error checking task ownership", e);
                    callback.onError("Error checking task ownership: " + e.getMessage());
                });
    }
}

Step 8: Update ViewModels

Update UserViewModel:

package com.example.taskmaster.viewmodel;

import android.app.Application;
import android.util.Log;

import androidx.annotation.NonNull;
import androidx.lifecycle.AndroidViewModel;
import androidx.lifecycle.LiveData;
import androidx.lifecycle.MutableLiveData;

import com.example.taskmaster.model.User;
import com.example.taskmaster.repository.UserRepository;

public class UserViewModel extends AndroidViewModel {
    private static final String TAG = "UserViewModel";
    
    private final UserRepository userRepository;
    private final MutableLiveData<User> userLiveData = new MutableLiveData<>();
    private final MutableLiveData<String> errorLiveData = new MutableLiveData<>();
    private final MutableLiveData<Boolean> loadingLiveData = new MutableLiveData<>();

    public UserViewModel(@NonNull Application application) {
        super(application);
        userRepository = new UserRepository(application);
        
        // Check if user is already logged in
        User currentUser = userRepository.getCurrentUser();
        if (currentUser != null) {
            userLiveData.setValue(currentUser);
        }
    }

    public LiveData<User> getUserLiveData() {
        return userLiveData;
    }

    public LiveData<String> getErrorLiveData() {
        return errorLiveData;
    }

    public LiveData<Boolean> getLoadingLiveData() {
        return loadingLiveData;
    }

    public void login(String email, String password) {
        loadingLiveData.setValue(true);
        userRepository.login(email, password, new UserRepository.AuthCallback() {
            @Override
            public void onSuccess(User user) {
                userLiveData.setValue(user);
                loadingLiveData.setValue(false);
                Log.d(TAG, "Login successful for user: " + user.getEmail());
            }

            @Override
            public void onError(String message) {
                errorLiveData.setValue(message);
                loadingLiveData.setValue(false);
                Log.e(TAG, "Login error: " + message);
            }
        });
    }

    public void register(String username, String email, String password, String fullName) {
        loadingLiveData.setValue(true);
        userRepository.register(username, email, password, fullName, new UserRepository.AuthCallback() {
            @Override
            public void onSuccess(User user) {
                userLiveData.setValue(user);
                loadingLiveData.setValue(false);
                Log.d(TAG, "Registration successful for user: " + user.getEmail());
            }

            @Override
            public void onError(String message) {
                errorLiveData.setValue(message);
                loadingLiveData.setValue(false);
                Log.e(TAG, "Registration error: " + message);
            }
        });
    }

    public void logout() {
        userRepository.logout();
        userLiveData.setValue(null);
        Log.d(TAG, "User logged out");
    }

    public User getCurrentUser() {
        return userRepository.getCurrentUser();
    }
}

Update TaskViewModel:

package com.example.taskmaster.viewmodel;

import android.app.Application;
import android.util.Log;

import androidx.annotation.NonNull;
import androidx.lifecycle.AndroidViewModel;
import androidx.lifecycle.LiveData;
import androidx.lifecycle.MutableLiveData;

import com.example.taskmaster.model.Task;
import com.example.taskmaster.repository.TaskRepository;

import java.util.List;

public class TaskViewModel extends AndroidViewModel {
    private static final String TAG = "TaskViewModel";
    
    private final TaskRepository taskRepository;
    private final MutableLiveData<List<Task>> tasksLiveData = new MutableLiveData<>();
    private final MutableLiveData<String> messageLiveData = new MutableLiveData<>();
    private final MutableLiveData<String> errorLiveData = new MutableLiveData<>();
    private final MutableLiveData<Boolean> loadingLiveData = new MutableLiveData<>();

    public TaskViewModel(@NonNull Application application) {
        super(application);
        taskRepository = new TaskRepository(application);
    }

    public LiveData<List<Task>> getTasksLiveData() {
        return tasksLiveData;
    }

    public LiveData<String> getMessageLiveData() {
        return messageLiveData;
    }

    public LiveData<String> getErrorLiveData() {
        return errorLiveData;
    }

    public LiveData<Boolean> getLoadingLiveData() {
        return loadingLiveData;
    }

    public void loadTasks() {
        loadingLiveData.setValue(true);
        taskRepository.getAllTasks(new TaskRepository.TaskCallback() {
            @Override
            public void onSuccess(List<Task> tasks) {
                tasksLiveData.setValue(tasks);
                loadingLiveData.setValue(false);
                Log.d(TAG, "Loaded " + tasks.size() + " tasks");
            }

            @Override
            public void onError(String message) {
                errorLiveData.setValue(message);
                loadingLiveData.setValue(false);
                Log.e(TAG, "Error loading tasks: " + message);
            }
        });
    }

    public void createTask(Task task) {
        loadingLiveData.setValue(true);
        taskRepository.createTask(task, new TaskRepository.TaskOperationCallback() {
            @Override
            public void onSuccess(String message) {
                messageLiveData.setValue(message);
                loadTasks(); // Reload tasks after creating
                Log.d(TAG, "Task created: " + message);
            }

            @Override
            public void onError(String message) {
                errorLiveData.setValue(message);
                loadingLiveData.setValue(false);
                Log.e(TAG, "Error creating task: " + message);
            }
        });
    }

    public void updateTask(Task task) {
        loadingLiveData.setValue(true);
        taskRepository.updateTask(task, new TaskRepository.TaskOperationCallback() {
            @Override
            public void onSuccess(String message) {
                messageLiveData.setValue(message);
                loadTasks(); // Reload tasks after updating
                Log.d(TAG, "Task updated: " + message);
            }

            @Override
            public void onError(String message) {
                errorLiveData.setValue(message);
                loadingLiveData.setValue(false);
                Log.e(TAG, "Error updating task: " + message);
            }
        });
    }

    public void deleteTask(String taskId) {
        loadingLiveData.setValue(true);
        taskRepository.deleteTask(taskId, new TaskRepository.TaskOperationCallback() {
            @Override
            public void onSuccess(String message) {
                messageLiveData.setValue(message);
                loadTasks(); // Reload tasks after deleting
                Log.d(TAG, "Task deleted: " + message);
            }

            @Override
            public void onError(String message) {
                errorLiveData.setValue(message);
                loadingLiveData.setValue(false);
                Log.e(TAG, "Error deleting task: " + message);
            }
        });
    }
}

Step 9: Update UI Components

The UI components (activities, fragments, adapters) can remain largely the same as your original implementation, with minor adjustments to work with the new Firebase backend.

Step 10: Update AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools">

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    <application
        android:allowBackup="true"
        android:dataExtractionRules="@xml/data_extraction_rules"
        android:fullBackupContent="@xml/backup_rules"
        android:icon="@drawable/ic_logo"
        android:label="@string/app_name"
        android:roundIcon="@drawable/ic_logo"
        android:supportsRtl="true"
        android:theme="@style/Theme.Taskmaster"
        tools:targetApi="31">

        <!-- Login Activity (Launch Activity) -->
        <activity
            android:name=".view.LoginActivity"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <!-- Main Activity -->
        <activity
            android:name=".view.MainActivity"
            android:exported="false" />
    </application>

</manifest>

Benefits of This Approach

No Server-Side Code: You don't need to manage PHP files or MySQL databases
Reliable Authentication: Firebase Auth handles user registration and login securely
Real-time Database: Firestore provides real-time updates when data changes
Scalability: Firebase automatically scales as your app grows
Free Tier: Firebase has a generous free tier that's more than enough for your app
No 403 Errors: You won't encounter the server permission issues you're facing now

This approach completely eliminates the need for your PHP backend and the associated 403 errors. Firebase provides a much more reliable and easier-to-implement solution for your Taskmaster app.

Complete Recode: Taskmaster App with InfinityFree Hosting

Since you want to stick with InfinityFree, let's completely recode the backend solution to make it work. I'll provide a step-by-step guide that should resolve the 403 error.

Part 1: Create a Simple Backend API

Let's create a simplified API that will definitely work on InfinityFree:

Step 1: Create a Single API File

Log in to your InfinityFree control panel
Go to the File Manager
Navigate to the htdocs directory (not inside any subfolder)
Create a new file called taskmaster_api.php with this content:

<?php
// Enable error reporting
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

// Allow cross-origin requests
header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Methods: POST, GET, OPTIONS");
header("Access-Control-Allow-Headers: Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With");

// Handle preflight OPTIONS request
if ($_SERVER['REQUEST_METHOD'] === 'OPTIONS') {
    http_response_code(200);
    exit();
}

// Set content type to JSON
header("Content-Type: application/json; charset=UTF-8");

// Log the request for debugging
$request_data = file_get_contents("php://input");
error_log("Received request: " . $request_data);

// Create a simple database connection function
function getConnection() {
    $host = "sql.infinityfree.com"; // Replace with your actual database host
    $db_name = "epiz_34567890_taskmaster"; // Replace with your actual database name
    $username = "epiz_34567890"; // Replace with your actual database username
    $password = "your_password"; // Replace with your actual database password
    
    try {
        $conn = new PDO("mysql:host=" . $host . ";dbname=" . $db_name, $username, $password);
        $conn->exec("set names utf8");
        return $conn;
    } catch(PDOException $exception) {
        return null;
    }
}

// Get the request data
$data = json_decode($request_data);

// Check if action parameter exists
if (!isset($_GET['action'])) {
    echo json_encode(array("status" => "error", "message" => "No action specified"));
    exit();
}

$action = $_GET['action'];

// Handle different actions
switch ($action) {
    case "login":
        // Handle login
        if (isset($data->email) && isset($data->password)) {
            // For testing, just return success without database
            echo json_encode(array(
                "status" => "success",
                "message" => "Login successful.",
                "user_id" => 1,
                "username" => "testuser",
                "email" => $data->email,
                "full_name" => "Test User",
                "token" => bin2hex(random_bytes(16))
            ));
        } else {
            http_response_code(400);
            echo json_encode(array("status" => "error", "message" => "Email and password required"));
        }
        break;
        
    case "register":
        // Handle registration
        if (isset($data->username) && isset($data->email) && isset($data->password) && isset($data->full_name)) {
            // For testing, just return success without database
            echo json_encode(array(
                "status" => "success",
                "message" => "Registration successful.",
                "user_id" => 1,
                "username" => $data->username,
                "email" => $data->email,
                "full_name" => $data->full_name,
                "token" => bin2hex(random_bytes(16))
            ));
        } else {
            http_response_code(400);
            echo json_encode(array("status" => "error", "message" => "All fields are required"));
        }
        break;
        
    case "get_tasks":
        // Return dummy tasks for testing
        echo json_encode(array(
            "status" => "success",
            "records" => array(
                array(
                    "task_id" => 1,
                    "title" => "Complete project proposal",

                    "due_date" => "2023-05-15 00:00:00",

                    "priority_color" => "#f56565",
                    "category_name" => "Work",
                    "category_color" => "#4299e1",
                    "status_name" => "To Do"
                ),
                array(
                    "task_id" => 2,
                    "title" => "Buy groceries",
                    "description" => "Get milk, eggs, and bread",
                    "due_date" => "2023-05-10 00:00:00",
                    "priority_name" => "Medium",
                    "priority_color" => "#ed8936",
                    "category_name" => "Personal",
                    "category_color" => "#48bb78",
                    "status_name" => "Completed"
                )
            )
        ));
        break;
        
    case "create_task":
        // Handle task creation
        if (isset($data->title) && isset($data->user_id)) {
            echo json_encode(array(
                "status" => "success",
                "message" => "Task created successfully",
                "task_id" => 3
            ));
        } else {
            http_response_code(400);
            echo json_encode(array("status" => "error", "message" => "Title and user_id are required"));
        }
        break;
        
    case "update_task":
        // Handle task update
        if (isset($data->task_id) && isset($data->title)) {
            echo json_encode(array(
                "status" => "success",
                "message" => "Task updated successfully"
            ));
        } else {
            http_response_code(400);
            echo json_encode(array("status" => "error", "message" => "Task ID and title are required"));
        }
        break;
        
    case "delete_task":
        // Handle task deletion
        if (isset($data->task_id)) {
            echo json_encode(array(
                "status" => "success",
                "message" => "Task deleted successfully"
            ));
        } else {
            http_response_code(400);
            echo json_encode(array("status" => "error", "message" => "Task ID is required"));
        }
        break;
        
    case "test":
        // Simple test endpoint
        echo json_encode(array(
            "status" => "success",
            "message" => "API is working!",
            "server_info" => array(
                "php_version" => phpversion(),
                "server_software" => $_SERVER['SERVER_SOFTWARE'],
                "request_method" => $_SERVER['REQUEST_METHOD'],
                "received_data" => $data
            )
        ));
        break;
        
    default:
        http_response_code(400);
        echo json_encode(array("status" => "error", "message" => "Unknown action: " . $action));
        break;
}
?>

Step 2: Test the API

Open your browser and navigate to: http://taskmaster.free.nf/taskmaster_api.php?action=test
You should see a JSON response like:
{"status":"success","message":"API is working!","server_info":{"php_version":"7.4.30","server_software":"Apache","request_method":"GET","received_data":null}}
If this works, your API is functioning correctly!

Part 2: Update Your Android App

Now let's update your Android app to use this simplified API:

Step 1: Update ApiClient.java

package com.example.taskmaster.network;

import android.content.Context;
import android.util.Log;

import com.android.volley.DefaultRetryPolicy;
import com.android.volley.Request;
import com.android.volley.RequestQueue;
import com.android.volley.Response;
import com.android.volley.VolleyError;
import com.android.volley.toolbox.JsonObjectRequest;
import com.android.volley.toolbox.Volley;

import org.json.JSONObject;

import java.util.HashMap;
import java.util.Map;

public class ApiClient {
    private static final String TAG = "ApiClient";
    private static ApiClient instance;
    private RequestQueue requestQueue;
    private static Context ctx;

    // Base URL of your API hosted on Infinity Free
    private static final String BASE_URL = "http://taskmaster.free.nf/taskmaster_api.php?action=";

    private ApiClient(Context context) {

            callback.onError("Error creating request: " + e.getMessage());
        }
    }
}

Part 3: Test the Solution

Make sure you've uploaded the taskmaster_api.php file to your htdocs directory on InfinityFree
Update your Android app with the new code
Run your app and try to login or register

This simplified approach should work because:

We're using a single PHP file instead of a complex structure
We're not relying on database connections initially (using dummy data)
We're using proper headers for CORS and content type
We're using a simple GET parameter for the action instead of complex routing

If you still encounter issues, try these additional steps:

Test the API directly in your browser: http://taskmaster.free.nf/taskmaster_api.php?action=test
Check your InfinityFree error logs if available
Add more detailed error logging to the PHP file

Let me know if this approach works for you!

Complete Rebuild: Taskmaster App with Firebase Backend

Step 1: Set Up Firebase Project

Go to Firebase Console
Click "Add project"
Name it "Taskmaster"
Follow the setup wizard (you can disable Google Analytics if you want)
Once created, click "Continue"

Step 2: Add Firebase to Your Android Project

In Firebase Console, click on the Android icon to add an Android app
Enter your package name: com.example.taskmaster
Register the app
Download the google-services.json file
Place this file in your app directory in Android Studio

Step 3: Update Your Gradle Files

Update your project-level build.gradle:

buildscript {
    repositories {
        google()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:7.0.4'
        classpath 'com.google.gms:google-services:4.3.15'
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

Update your app-level build.gradle:

plugins {
    id 'com.android.application'
    id 'com.google.gms.google-services'
}

android {
    namespace "com.example.taskmaster"
    compileSdk 34

    defaultConfig {
        applicationId "com.example.taskmaster"
        minSdk 21
        targetSdk 34
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    buildFeatures {
        viewBinding true
    }
}

dependencies {
    implementation 'androidx.appcompat:appcompat:1.6.1'
    implementation 'com.google.android.material:material:1.10.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
    
    // Firebase
    implementation platform('com.google.firebase:firebase-bom:32.3.1')
    implementation 'com.google.firebase:firebase-auth'
    implementation 'com.google.firebase:firebase-firestore'
    
    // ViewModel and LiveData
    implementation 'androidx.lifecycle:lifecycle-viewmodel:2.6.2'
    implementation 'androidx.lifecycle:lifecycle-livedata:2.6.2'
    
    // RecyclerView
    implementation 'androidx.recyclerview:recyclerview:1.3.2'
    
    // CircleImageView for profile pictures
    implementation 'de.hdodenhof:circleimageview:3.1.0'
    
    // Testing
    testImplementation 'junit:junit:4.13.2'
    androidTestImplementation 'androidx.test.ext:junit:1.1.5'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.5.1'
}

Step 4: Enable Firebase Authentication

In Firebase Console, go to "Authentication"
Click "Get Started"
Enable "Email/Password" authentication
Save the changes

Step 5: Create Firestore Database

In Firebase Console, go to "Firestore Database"
Click "Create database"
Start in test mode (we'll update security rules later)
Choose a location close to you
Click "Enable"

Step 6: Update Your Model Classes

Create a new User model:

package com.example.taskmaster.model;

public class User {
    private String userId;
    private String username;
    private String email;
    private String fullName;

    public User() {
        // Required empty constructor for Firestore
    }

    public User(String userId, String username, String email, String fullName) {
        this.userId = userId;
        this.username = username;
        this.email = email;
        this.fullName = fullName;
    }

    // Getters and setters
    public String getUserId() {
        return userId;
    }

    public void setUserId(String userId) {
        this.userId = userId;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getFullName() {
        return fullName;
    }

    public void setFullName(String fullName) {
        this.fullName = fullName;
    }
}

Update your Task model:

package com.example.taskmaster.model;

import java.util.Date;

public class Task {
    private String taskId;
    private String userId;
    private String title;
    private String description;
    private Date dueDate;
    private String priority;
    private String category;
    private boolean completed;
    private Date createdAt;

    public Task() {
        // Required empty constructor for Firestore
    }

    // Constructor with all fields
    public Task(String taskId, String userId, String title, String description, 
                Date dueDate, String priority, String category, boolean completed, Date createdAt) {
        this.taskId = taskId;
        this.userId = userId;
        this.title = title;
        this.description = description;
        this.dueDate = dueDate;
        this.priority = priority;
        this.category = category;
        this.completed = completed;
        this.createdAt = createdAt;
    }

    // Getters and setters
    public String getTaskId() {
        return taskId;
    }

    public void setTaskId(String taskId) {
        this.taskId = taskId;
    }

    public String getUserId() {
        return userId;
    }

    public void setUserId(String userId) {
        this.userId = userId;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public Date getDueDate() {
        return dueDate;
    }

    public void setDueDate(Date dueDate) {
        this.dueDate = dueDate;
    }

    public String getPriority() {
        return priority;
    }

    public void setPriority(String priority) {
        this.priority = priority;
    }

    public String getCategory() {
        return category;
    }

    public void setCategory(String category) {
        this.category = category;
    }

    public boolean isCompleted() {
        return completed;
    }

    public void setCompleted(boolean completed) {
        this.completed = completed;
    }

    public Date getCreatedAt() {
        return createdAt;
    }

    public void setCreatedAt(Date createdAt) {
        this.createdAt = createdAt;
    }
}

Step 7: Create Repository Classes

Create UserRepository:

package com.example.taskmaster.repository;

import android.content.Context;
import android.content.SharedPreferences;
import android.util.Log;

import com.google.firebase.auth.FirebaseAuth;
import com.google.firebase.auth.FirebaseUser;
import com.google.firebase.firestore.FirebaseFirestore;
import com.google.gson.Gson;

import com.example.taskmaster.model.User;

import java.util.HashMap;
import java.util.Map;

public class UserRepository {
    private static final String TAG = "UserRepository";
    private static final String PREF_NAME = "TaskmasterPrefs";
    private static final String KEY_USER = "user";
    
    private final Context context;
    private final FirebaseAuth auth;
    private final FirebaseFirestore db;
    private final SharedPreferences sharedPreferences;

    public UserRepository(Context context) {
        this.context = context;
        this.auth = FirebaseAuth.getInstance();
        this.db = FirebaseFirestore.getInstance();
        this.sharedPreferences = context.getSharedPreferences(PREF_NAME, Context.MODE_PRIVATE);
    }

    public interface AuthCallback {
        void onSuccess(User user);
        void onError(String message);
    }

    public void login(String email, String password, final AuthCallback callback) {
        auth.signInWithEmailAndPassword(email, password)
                .addOnCompleteListener(task -> {
                    if (task.isSuccessful()) {
                        FirebaseUser firebaseUser = auth.getCurrentUser();
                        if (firebaseUser != null) {
                            // Get user data from Firestore
                            db.collection("users").document(firebaseUser.getUid())
                                    .get()
                                    .addOnSuccessListener(documentSnapshot -> {
                                        if (documentSnapshot.exists()) {
                                            User user = documentSnapshot.toObject(User.class);
                                            // Save user to SharedPreferences
                                            saveUser(user);
                                            callback.onSuccess(user);
                                        } else {
                                            // Create a basic user if not in Firestore yet
                                            User newUser = new User(
                                                    firebaseUser.getUid(),
                                                    email.split("@")[0], // Simple username from email
                                                    email,
                                                    firebaseUser.getDisplayName() != null ? 
                                                            firebaseUser.getDisplayName() : "User"
                                            );
                                            saveUserToFirestore(newUser, callback);

                                    });

                    callback.onError("Error checking task ownership: " + e.getMessage());
                });
    }
}

Step 8: Update ViewModels

Update UserViewModel:

package com.example.taskmaster.viewmodel;

import android.app.Application;
import android.util.Log;

import androidx.annotation.NonNull;
import androidx.lifecycle.AndroidViewModel;
import androidx.lifecycle.LiveData;
import androidx.lifecycle.MutableLiveData;

import com.example.taskmaster.model.User;
import com.example.taskmaster.repository.UserRepository;

public class UserViewModel extends AndroidViewModel {

    private final UserRepository userRepository;
    private final MutableLiveData<User> userLiveData = new MutableLiveData<>();
    private final MutableLiveData<String> errorLiveData = new MutableLiveData<>();
    private final MutableLiveData<Boolean> loadingLiveData = new MutableLiveData<>();

    public UserViewModel(@NonNull Application application) {
        super(application);
        userRepository = new UserRepository(application);
        
        // Check if user is already logged in
        User currentUser = userRepository.getCurrentUser();
        if (currentUser != null) {
            userLiveData.setValue(currentUser);
        }
    }

    public LiveData<User> getUserLiveData() {
        return userLiveData;
    }

    public LiveData<String> getErrorLiveData() {
        return errorLiveData;
    }

    public LiveData<Boolean> getLoadingLiveData() {
        return loadingLiveData;
    }

    public void login(String email, String password) {
        loadingLiveData.setValue(true);
        userRepository.login(email, password, new UserRepository.AuthCallback() {
            @Override
            public void onSuccess(User user) {
                userLiveData.setValue(user);
                loadingLiveData.setValue(false);
                Log.d(TAG, "Login successful for user: " + user.getEmail());
            }

            @Override
            public void onError(String message) {
                errorLiveData.setValue(message);
                loadingLiveData.setValue(false);
                Log.e(TAG, "Login error: " + message);
            }
        });
    }

    public void register(String username, String email, String password, String fullName) {
        loadingLiveData.setValue(true);
        userRepository.register(username, email, password, fullName, new UserRepository.AuthCallback() {
            @Override
            public void onSuccess(User user) {
                userLiveData.setValue(user);
                loadingLiveData.setValue(false);
                Log.d(TAG, "Registration successful for user: " + user.getEmail());
            }

            @Override
            public void onError(String message) {
                errorLiveData.setValue(message);
                loadingLiveData.setValue(false);
                Log.e(TAG, "Registration error: " + message);
            }
        });
    }

    public void logout() {
        userRepository.logout();
        userLiveData.setValue(null);
        Log.d(TAG, "User logged out");
    }

    public User getCurrentUser() {
        return userRepository.getCurrentUser();
    }
}

Update TaskViewModel:

package com.example.taskmaster.viewmodel;

import android.app.Application;
import android.util.Log;

import androidx.annotation.NonNull;
import androidx.lifecycle.AndroidViewModel;
import androidx.lifecycle.LiveData;
import androidx.lifecycle.MutableLiveData;

import com.example.taskmaster.model.Task;
import com.example.taskmaster.repository.TaskRepository;

import java.util.List;

public class TaskViewModel extends AndroidViewModel {
    private static final String TAG = "TaskViewModel";
    
    private final TaskRepository taskRepository;
    private final MutableLiveData<List<Task>> tasksLiveData = new MutableLiveData<>();
    private final MutableLiveData<String> messageLiveData = new MutableLiveData<>();
    private final MutableLiveData<String> errorLiveData = new MutableLiveData<>();
    private final MutableLiveData<Boolean> loadingLiveData = new MutableLiveData<>();

    public TaskViewModel(@NonNull Application application) {
        super(application);
        taskRepository = new TaskRepository(application);
    }

    public LiveData<List<Task>> getTasksLiveData() {
        return tasksLiveData;
    }

    public LiveData<String> getMessageLiveData() {
        return messageLiveData;
    }

    public LiveData<String> getErrorLiveData() {
        return errorLiveData;
    }

    public LiveData<Boolean> getLoadingLiveData() {
        return loadingLiveData;
    }

    public void loadTasks() {
        loadingLiveData.setValue(true);
        taskRepository.getAllTasks(new TaskRepository.TaskCallback() {
            @Override
            public void onSuccess(List<Task> tasks) {
                tasksLiveData.setValue(tasks);
                loadingLiveData.setValue(false);
                Log.d(TAG, "Loaded " + tasks.size() + " tasks");
            }

            @Override
            public void onError(String message) {
                errorLiveData.setValue(message);
                loadingLiveData.setValue(false);
                Log.e(TAG, "Error loading tasks: " + message);
            }
        });
    }

    public void createTask(Task task) {
        loadingLiveData.setValue(true);
        taskRepository.createTask(task, new TaskRepository.TaskOperationCallback() {
            @Override
            public void onSuccess(String message) {
                messageLiveData.setValue(message);
                loadTasks(); // Reload tasks after creating
                Log.d(TAG, "Task created: " + message);
            }

            @Override
            public void onError(String message) {
                errorLiveData.setValue(message);
                loadingLiveData.setValue(false);
                Log.e(TAG, "Error creating task: " + message);
            }
        });
    }

    public void updateTask(Task task) {
        loadingLiveData.setValue(true);
        taskRepository.updateTask(task, new TaskRepository.TaskOperationCallback() {
            @Override
            public void onSuccess(String message) {
                messageLiveData.setValue(message);
                loadTasks(); // Reload tasks after updating
                Log.d(TAG, "Task updated: " + message);
            }

            @Override
            public void onError(String message) {
                errorLiveData.setValue(message);
                loadingLiveData.setValue(false);
                Log.e(TAG, "Error updating task: " + message);
            }
        });
    }

    public void deleteTask(String taskId) {
        loadingLiveData.setValue(true);
        taskRepository.deleteTask(taskId, new TaskRepository.TaskOperationCallback() {
            @Override
            public void onSuccess(String message) {
                messageLiveData.setValue(message);
                loadTasks(); // Reload tasks after deleting
                Log.d(TAG, "Task deleted: " + message);
            }

            @Override
            public void onError(String message) {
                errorLiveData.setValue(message);
                loadingLiveData.setValue(false);
                Log.e(TAG, "Error deleting task: " + message);
            }
        });
    }
}

Step 9: Update UI Components

The UI components (activities, fragments, adapters) can remain largely the same as your original implementation, with minor adjustments to work with the new Firebase backend.

Step 10: Update AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools">

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    <application
        android:allowBackup="true"
        android:dataExtractionRules="@xml/data_extraction_rules"
        android:fullBackupContent="@xml/backup_rules"
        android:icon="@drawable/ic_logo"
        android:label="@string/app_name"
        android:roundIcon="@drawable/ic_logo"
        android:supportsRtl="true"
        android:theme="@style/Theme.Taskmaster"
        tools:targetApi="31">

        <!-- Login Activity (Launch Activity) -->
        <activity
            android:name=".view.LoginActivity"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <!-- Main Activity -->
        <activity
            android:name=".view.MainActivity"
            android:exported="false" />
    </application>

</manifest>

Benefits of This Approach

No Server-Side Code: You don't need to manage PHP files or MySQL databases
Reliable Authentication: Firebase Auth handles user registration and login securely
Real-time Database: Firestore provides real-time updates when data changes
Scalability: Firebase automatically scales as your app grows
Free Tier: Firebase has a generous free tier that's more than enough for your app
No 403 Errors: You won't encounter the server permission issues you're facing now

This approach completely eliminates the need for your PHP backend and the associated 403 errors. Firebase provides a much more reliable and easier-to-implement solution for your Taskmaster app.

Let me know if you'd like me to explain any part of this implementation in more detail!

Complete Recode: Taskmaster App with InfinityFree Hosting

Since you want to stick with InfinityFree, let's completely recode the backend solution to make it work. I'll provide a step-by-step guide that should resolve the 403 error.

Part 1: Create a Simple Backend API

Let's create a simplified API that will definitely work on InfinityFree:

Step 1: Create a Single API File

Log in to your InfinityFree control panel
Go to the File Manager
Navigate to the htdocs directory (not inside any subfolder)
Create a new file called taskmaster_api.php with this content:

<?php
// Enable error reporting
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

// Allow cross-origin requests
header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Methods: POST, GET, OPTIONS");
header("Access-Control-Allow-Headers: Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With");

// Handle preflight OPTIONS request
if ($_SERVER['REQUEST_METHOD'] === 'OPTIONS') {
    http_response_code(200);
    exit();
}

// Set content type to JSON
header("Content-Type: application/json; charset=UTF-8");

// Log the request for debugging
$request_data = file_get_contents("php://input");
error_log("Received request: " . $request_data);

// Create a simple database connection function
function getConnection() {
    $host = "sql.infinityfree.com"; // Replace with your actual database host
    $db_name = "epiz_34567890_taskmaster"; // Replace with your actual database name
    $username = "epiz_34567890"; // Replace with your actual database username
    $password = "your_password"; // Replace with your actual database password
    
    try {
        $conn = new PDO("mysql:host=" . $host . ";dbname=" . $db_name, $username, $password);
        $conn->exec("set names utf8");
        return $conn;
    } catch(PDOException $exception) {
        return null;
    }
}

// Get the request data
$data = json_decode($request_data);

// Check if action parameter exists
if (!isset($_GET['action'])) {
    echo json_encode(array("status" => "error", "message" => "No action specified"));
    exit();
}

$action = $_GET['action'];

// Handle different actions
switch ($action) {
    case "login":
        // Handle login
        if (isset($data->email) && isset($data->password)) {
            // For testing, just return success without database
            echo json_encode(array(
                "status" => "success",
                "message" => "Login successful.",
                "user_id" => 1,

?>

Step 2: Test the API

Open your browser and navigate to: http://taskmaster.free.nf/taskmaster_api.php?action=test
You should see a JSON response like:
{"status":"success","message":"API is working!","server_info":{"php_version":"7.4.30","server_software":"Apache","request_method":"GET","received_data":null}}
If this works, your API is functioning correctly!

Part 2: Update Your Android App

Now let's update your Android app to use this simplified API:

Step 1: Update ApiClient.java

package com.example.taskmaster.network;

import android.content.Context;
import android.util.Log;

import com.android.volley.DefaultRetryPolicy;
import com.android.volley.Request;
import com.android.volley.RequestQueue;
import com.android.volley.Response;
import com.android.volley.VolleyError;
import com.android.volley.toolbox.JsonObjectRequest;
import com.android.volley.toolbox.Volley;

import java.util.HashMap;
import java.util.Map;

public class ApiClient {
    private static final String TAG = "ApiClient";
    private static ApiClient instance;
    private RequestQueue requestQueue;
    private static Context ctx;

    // Base URL of your API hosted on Infinity Free
    private static final String BASE_URL = "http://taskmaster.free.nf/taskmaster_api.php?action=";

    private ApiClient(Context context) {
        ctx = context;
        requestQueue = getRequestQueue();
    }

    public static synchronized ApiClient getInstance(Context context) {
        if (instance == null) {
            instance = new ApiClient(context);
        }
        return instance;
    }

    public RequestQueue getRequestQueue() {
        if (requestQueue == null) {
            requestQueue = Volley.newRequestQueue(ctx.getApplicationContext());
        }
        return requestQueue;
    }

    public <T> void addToRequestQueue(Request<T> req) {
        getRequestQueue().add(req);
    }

    public interface ApiResponseCallback {
        void onSuccess(JSONObject response);
        void onError(VolleyError error);
    }

    // Method to make a POST request

                new Response.Listener<JSONObject>() {
                    @Override
                    public void onResponse(JSONObject response) {
                        Log.d(TAG, "Response: " + response.toString());
                        callback.onSuccess(response);
                    }
                },
                new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        Log.e(TAG, "Error: " + error.toString());
                        callback.onError(error);
                    }
                }
        ) {
            @Override
            public Map<String, String> getHeaders() {
                Map<String, String> headers = new HashMap<>();
                headers.put("Content-Type", "application/json");
                return headers;
            }
        };
        
        // Set a longer timeout
        jsonObjectRequest.setRetryPolicy(new DefaultRetryPolicy(
                30000, // 30 seconds timeout
                DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
                DefaultRetryPolicy.DEFAULT_BACKOFF_MULT
        ));
        
        addToRequestQueue(jsonObjectRequest);
    }

    // Method to make a GET request
    public void get(String action, final ApiResponseCallback callback) {
        String url = BASE_URL + action;
        Log.d(TAG, "Making GET request to: " + url);
        
        JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(
                Request.Method.GET,
                url,
                null,
                new Response.Listener<JSONObject>() {
                    @Override
                    public void onResponse(JSONObject response) {
                        Log.d(TAG, "Response: " + response.toString());
                        callback.onSuccess(response);
                    }
                },
                new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        Log.e(TAG, "Error: " + error.toString());
                        callback.onError(error);
                    }
                }
        );
        
        // Set a longer timeout
        jsonObjectRequest.setRetryPolicy(new DefaultRetryPolicy(
                30000, // 30 seconds timeout
                DefaultRetryPolicy.DEFAULT_MAX_RETRIES,

        ));
        
        addToRequestQueue(jsonObjectRequest);
    }
}

Step 2: Update UserRepository.java

    public UserRepository(Context context) {
        this.context = context;
        this.apiClient = ApiClient.getInstance(context);
        this.sharedPreferences = context.getSharedPreferences(PREF_NAME, Context.MODE_PRIVATE);
    }

    public interface AuthCallback {

    }

Part 3: Test the Solution

Make sure you've uploaded the taskmaster_api.php file to your htdocs directory on InfinityFree
Update your Android app with the new code
Run your app and try to login or register

This simplified approach should work because:

We're using a single PHP file instead of a complex structure
We're not relying on database connections initially (using dummy data)
We're using proper headers for CORS and content type
We're using a simple GET parameter for the action instead of complex routing

If you still encounter issues, try these additional steps:

Test the API directly in your browser: http://taskmaster.free.nf/taskmaster_api.php?action=test
Check your InfinityFree error logs if available
Add more detailed error logging to the PHP file

Let me know if this approach works for you!

i still got the same error when i log in and register can recode it from the start so that i can follow it, solve this error as much as you can please
