# Running the Industrial Palm AI Mobile App

Follow these steps to start the development environment and run the app on your device or emulator.

## Prerequisites

1.  **Node.js**: Ensure you have Node.js installed (LTS recommended).
2.  **Android Studio**: For Android development, installed with SDK and an emulator or physical device connected via ADB.
3.  **Xcode**: For iOS development (Mac only), installed with command-line tools.
4.  **Dependencies**: Run `npm install` in the `mobile/` directory to ensure all packages are ready.

## Quick Start

### 1. Start the Metro Bundler
The Metro bundler must be running for React Native to serve your JavaScript code.
```bash
cd mobile
npm start
```

### 2. Run on Android
In a new terminal window:
```bash
cd mobile
npm run android
```

### 3. Run on iOS (Mac only)
In a new terminal window:
```bash
cd mobile
npm run ios
```

## Important Notes

- **Camera Access**: The app requires camera permissions. It will prompt you on first launch.
- **Model Inference**: The AI model is located in `assets/best.tflite`. It is loaded automatically on startup.
- **Abnormal Alert**: Detections for "Abnormal" and "Empty_Bunch" will appear with **red boxes** per industrial priority.

## Troubleshooting

- **Build Errors**: If the build fails, try running `npx react-native doctor` inside the `mobile/` folder to check your environment setup.
- **Model Not Found**: Ensure `mobile/assets/best.tflite` exists.
- **Node Modules**: If you encounter dependency issues, run `rm -rf node_modules && npm install`.
