+# 3D Tetris - Android App
+
+This is the native Android implementation of the 3D Tetris game. The mobile-specific optimizations from the web app have been removed, and instead, this native app has been created to provide a better experience on Android devices.
+
+## Project Structure
+
+- `app/src/main/java/com/tetris3d/` - Contains all Java/Kotlin source files
+  - `MainActivity.kt` - Main activity that hosts the game
+  - `game/` - Game logic implementation
+  - `views/` - Custom views for rendering game elements
+
+- `app/src/main/res/` - Contains all resources
+  - `layout/` - XML layouts for the UI
+  - `values/` - String resources, colors, and themes
+  - `drawable/` - Icon and image resources
+
+## Features
+
+- 3D Tetris gameplay with modern graphics
+- Customizable options for 3D effects and animations
+- Physical button controls optimized for touch
+- Score tracking and level progression
+- Game state persistence
+
+## Required Implementation
+
+The following components still need to be implemented to complete the Android app:
+
+1. TetrisGame class - Core game logic ported from JavaScript
+2. TetrisGameView - Custom view for rendering the game
+3. NextPieceView - Custom view for rendering the next piece preview
+4. Tetromino classes - Classes for different tetromino pieces
+5. Game renderer - OpenGL ES or Canvas-based renderer for the 3D effects
+
+## Dependencies
+
+- AndroidX libraries for UI components
+- Kotlin coroutines for game loop threading
+
+## Building and Running
+
+1. Open the project in Android Studio
+2. Build the project using Gradle
+3. Deploy to an Android device or emulator
+
+## Development Process
+
+The Android app was created by:
+
+1. Analyzing the web implementation of the game
+2. Removing mobile-specific optimizations from the web code
+3. Creating a native Android app structure
+4. Implementing the UI layouts and resources
+5. Porting the core game logic from JavaScript to Kotlin
+6. Adding Android-specific features and optimizations
+
+The core game mechanics are kept identical to the web version, ensuring a consistent experience across platforms.
