An Android application to extract and create Ren'Py RPA archives and decompile RPYC scripts directly on your device.

• Extract RPA Archives: Unpack Ren'Py game archives to access images, scripts, audio, and other assets
• Create RPA Archives: Package files and folders into RPA v3 format archives
• Decompile RPYC Scripts: Convert compiled .rpyc files back to readable .rpy source scripts
• Batch Operations: Extract multiple RPA files or decompile multiple RPYC files at once
• Multi-Select Support: Long-press to select multiple files or folders for batch operations
• Smart Directory Defaults: Output directory automatically defaults to the location of selected input files
• Real-time Progress Tracking: View extraction/creation/decompilation progress with file counts, speed, and ETA

• Android 11 or higher
• MANAGE_EXTERNAL_STORAGE permission: Required for direct file system access
• Storage: Enough space for extracted/created archives

1. Download the latest APK from the Releases page
2. Enable "Install from Unknown Sources" if needed
3. Install the APK
4. Grant storage permissions when prompted (MANAGE_EXTERNAL_STORAGE)

• Android Studio Arctic Fox or later
• Android SDK with API 34+
• Python 3.8+ (for Chaquopy build)
• Gradle 8.0+

1. Clone the repository:

   git clone https://github.com/yourusername/Rentool.git
   cd Rentool

2. Open the project in Android Studio

3. Sync Gradle files (Android Studio should prompt automatically)

4. Build the APK:

   • Via Android Studio: Build → Build Bundle(s) / APK(s) → Build APK(s)
   • Via Command Line:

     ./gradlew assembleDebug

5. The APK will be located at:

   app/build/outputs/apk/debug/app-debug.apk
   

The project uses Chaquopy to integrate Python for RPA archive operations and RPYC decompilation. Chaquopy will automatically detect your Python installation during build.

If auto-detection fails, you can manually specify your Python path in app/build.gradle:

python {
    buildPython "/path/to/python"
}

1. Tap the "Extract RPA" card
2. Browse and select one or more .rpa files:
   • Single tap: Select one file
   • Long-press: Enter multi-select mode to choose multiple files
3. Select the destination folder (defaults to the folder containing the RPA files)
4. Wait for extraction to complete
5. Files will be extracted to the chosen directory (overwrites existing files)

1. Tap the "Create RPA" card
2. Browse and select files/folders to archive:
   • Single tap: Select one folder
   • Long-press: Enter multi-select mode to choose multiple items
3. Enter a name for the output RPA file (e.g., archive.rpa)
4. Wait for creation to complete
5. The RPA file will be created in the parent directory of selected items

1. Tap the "Decompile RPYC" card
2. Browse and select .rpyc files or folders containing scripts:
   • Single tap: Select individual files or an entire folder (e.g., /game folder)
   • Long-press: Enter multi-select mode to choose multiple files/folders
3. Select the destination folder (defaults to the folder containing the RPYC files)
4. Wait for decompilation to complete
5. Decompiled .rpy files will be saved to the chosen directory

Tip: Selecting a game's /game folder is the fastest way to decompile all scripts at once.
