For years, CameraX in Compose felt like a second-class citizen. Wrapping PreviewView in AndroidView created a "View-shaped hole" that complicated lifecycles, broke Z-ordering, and made gesture handling a mathematical nightmare. That era ends now. With the new camera-compose artifact, we finally have a native solution. In this session, we will migrate from legacy wrappers to the new CameraXViewfinder. We’ll explore a reactive architecture where CameraX publishes SurfaceRequest objects to a StateFlow that your UI consumes. We will dive deep into: - CoordinateTransformer: Solving "tap-to-focus" math in a single line, handling sensor rotation and scaling automatically. - Implementation Modes: Choosing between EXTERNAL (SurfaceView) and EMBEDDED (TextureView) for the right balance of battery life vs. animation support. - Production Patterns: Handling permissions, foldables, and lifecycles cleanly. - Stop bridging two worlds. It’s time to make your camera code as beautiful as your UI.
