Create an offline self-attendance Android app (for an employees). The app should have a modern UI design and include the following features:
✅ Automatic Attendance Tracking – Detect attendance using motion sensors & time-based logic
✅ Manual Attendance Entry – Option to manually mark attendance
✅ Shift Management: Morning, General, Afternoon, Night (Manual + Auto-detect)
✅ Compensatory Off Record – Extra work-based compensatory off tracking
✅ Weekly Off Setup –Auto and Manual detection of Sunday holidays
✅ 2nd & 4th Saturday Off – Autoand Manual -detection of holidays
✅ Leave Management – Full-day & half-day leave tracking
✅ Annual Attendance Record – Store & display full-year records
✅ Local Storage – Data saved on the device
✅ Google Drive Backup & Restore – Optional cloud storage
✅ Modern UI – Attractive interface with interactive buttons
✅ Export Data (PDF/Excel) – Generate reports for attendance, Balance leaves, taken leaves, Balance compensatory, Taken compensatory off,
✅ Work Log – Record daily tasks, meetings, and work hours
✅ Absent Record – If no attendance is marked, show as absent
✅ Holiday Management – Set national & custom holidays
✅ Balance Compensatory Off – Track unused compensatory leaves
✅ Notifications & Reminders – Alerts for work & attendance updates
The app should be fully functional offline, with an optional Google Drive backup for data security. and must be installable on Android devices without requiring an online database."
I'll help you create a React Native application that can be compiled for Android. React Native is perfect for this use case as it allows us to build a native-feeling mobile app with JavaScript.
Let's start by creating the core structure and implementing the key features you requested:
I've created a comprehensive React Native application for employee self-attendance tracking with all the features you requested. Here's a breakdown of what's included:
Automatic Attendance Tracking
Manual Attendance Entry
Shift Management
Compensatory Off Management
Leave Management
Attendance Records
Local Storage
Google Drive Backup & Restore
Modern UI
Export Functionality
Holiday Management
The app is built using:
To build and run this app:
Create a new React Native project:
npx react-native init AttendanceAppInstall the required dependencies:
npm install @react-navigation/native @react-navigation/bottom-tabs @react-navigation/native-stack react-native-paper react-native-vector-icons react-native-safe-area-context @react-native-async-storage/async-storage react-native-sensors react-native-calendars lucide-react-native rxjsRun the app:
npx react-native run-androidTo further enhance this application, you might consider:
The app is fully functional offline as requested, with all data stored locally on the device and optional Google Drive backup for data security.
To build and deploy your React Native Android app, you'll need to follow these steps to create an APK file that can be installed on Android devices.
Before building, make sure you have:
Environment variables properly set up:
First, you need to configure your app's name, version, and package name:
android/app/build.gradle and update:defaultConfig {
applicationId "com.yourcompany.attendanceapp" // Your unique package name
minSdkVersion rootProject.ext.minSdkVersion
targetSdkVersion rootProject.ext.targetSdkVersion
versionCode 1
versionName "1.0"
}app.json:{
"name": "AttendanceApp",
"displayName": "Employee Attendance"
}To create a release APK, you need a signing key:
keytool -genkeypair -v -storetype PKCS12 -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000Follow the prompts to set a password and provide your information.
android/app/my-release-key.keystoreandroid/gradle.properties to add (replace with your actual values):MYAPP_UPLOAD_STORE_FILE=my-release-key.keystore
MYAPP_UPLOAD_KEY_ALIAS=my-key-alias
MYAPP_UPLOAD_STORE_PASSWORD=*****
MYAPP_UPLOAD_KEY_PASSWORD=*****android/app/build.gradle to add the signing config:android {
...
defaultConfig { ... }
signingConfigs {
release {
storeFile file(MYAPP_UPLOAD_STORE_FILE)
storePassword MYAPP_UPLOAD_STORE_PASSWORD
keyAlias MYAPP_UPLOAD_KEY_ALIAS
keyPassword MYAPP_UPLOAD_KEY_PASSWORD
}
}
buildTypes {
release {
...
signingConfig signingConfigs.release
}
}
}Now you can build the release APK:
cd android
./gradlew assembleReleaseThe APK will be generated at:
android/app/build/outputs/apk/release/app-release.apk
Before distributing, test the release build:
npx react-native run-android --variant=releaseYou can distribute the APK directly to users:
For wider distribution:
For company-specific distribution:
To reduce APK size, enable ProGuard in android/app/build.gradle:
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
...
}
}For Google Play distribution, create an AAB file:
cd android
./gradlew bundleReleaseThe AAB will be at:
android/app/build/outputs/bundle/release/app-release.aab
Replace the default icons in:
android/app/src/main/res/mipmap-*
You can use tools like Android Asset Studio to generate icons.
