Android Camerax Migrator

# Android Camerax Migrator This skill assists in migrating legacy Android camera implementations (Camera1 or raw Camera2 APIs) to the modern CameraX library. CameraX is a lifecycle-aware Jetpack library that simplifies camera operations by handling camera rotation issues and device dependencies. ## Key Capabilities - **Legacy to CameraX Migration**: Converts Camera1 or raw Camera2 APIs to CameraX. - **Lifecycle Awareness**: Ensures camera operations are in sync with the app lifecycle. - **Rotation Handling**: Automatically resolves camera rotation issues. - **Dependency Management**: Handles device-specific dependencies. ## When to Use Use this skill when developing Android applications that require modern camera functionality with lifecycle awareness and efficient camera operations. ## Example Use Cases - Developing a camera app that needs to handle various camera configurations. - Updating an existing app to use the latest camera APIs for better performance and reliability. ## Dependencies - Ensure you have CameraX version 1.3.0 or higher for interoperability. - Use Gradle dependencies as outlined in the skill documentation. ## Implementation Steps 1. **Add Dependencies**: Integrate CameraX dependencies into your project. 2. **Remove Legacy Implementation**: Eliminate old camera code and custom lifecycle handling. 3. **Initialize ProcessCameraProvider**: Bind camera use cases to the app lifecycle. 4. **Implement Preview & Tap-to-Focus**: Set up camera preview and focus functionality. 5. **Capture Photo**: Use ImageCapture to take photos with automatic rotation handling. 6. **Switch Cameras**: Easily switch between front and rear cameras. ## Constraints - Avoid manual camera lifecycle management. - Use `MeteringPointFactory` for focus calculations. - Close `ImageProxy` after use to prevent pipeline locks.
