App Builder

Let's create a simple app builder that allows you to customize a web application with different themes, names, and HTML content.

How to Use the App Builder

1. Settings Tab: Configure your app's name and theme color
2. HTML Editor Tab: Edit the HTML code for your web application
3. Preview Tab: See how your app will look and download the final HTML file

Features:

• Customize app name and theme color
• Edit HTML/CSS directly in the editor
• Live preview of your web application
• Download the complete HTML file

To use this app builder:

1. Click on the "Settings" tab to set your app name and theme color
2. Switch to the "HTML Editor" tab if you want to customize the HTML code
3. Go to the "Preview" tab and click "Generate Preview" to see your app
4. Click "Download Web App" to get your HTML file

Note: This is a web app builder that creates HTML files. For native mobile apps (APK/AAB files), you would need additional tools and services beyond what can be provided in this interface.

Android App Builder

Let me create an enhanced app builder that simulates APK/AAB file generation with a more comprehensive settings interface similar to the one you referenced.

How to Use the Android App Builder

This app builder simulates the process of creating an Android application with the following features:

Key Features:

1. App Settings

   • Set app name, package name, and version
   • Configure screen orientation
   • Enable/disable features like splash screen and notifications
   • Set required permissions

2. Design Customization

   • Choose primary theme color
   • Upload app icon and splash screen
   • Adjust font sizes

3. HTML Editor

   • Edit the HTML/CSS/JavaScript that will be displayed in your app
   • Create responsive layouts for mobile devices

4. Preview

   • See how your app will look on an Android device
   • Test the user interface before building

5. Build Process

   • Generate APK (Android Package) files for direct installation
   • Generate AAB (Android App Bundle) files for Google Play submission

How to Use:

1. Configure Settings: Start by setting your app name, package name, and other basic settings
2. Customize Design: Choose colors and upload your app icon
3. Edit HTML: Modify the HTML code to create your app's interface
4. Preview: Check how your app will look on an Android device
5. Build: Click the "Build APK" button to generate your Android app files
6. Download: Once built, download either the APK or AAB file

Note: This is a simulation of the app building process. The downloaded APK/AAB files are placeholders that demonstrate the concept. In a production environment, these files would be properly compiled Android applications that could be installed on devices or submitted to the Google Play Store.
