When adding camera capabilities to Android apps, developers had to look out for pitfalls. The recently introduced Jetpack CameraViewfinder API significantly improves the developer experience in this area. Internally it uses either a TextureView or SurfaceView to display the camera feed and applies transformations to correctly display the viewfinder, fixing aspect ratio, scale and rotation where necessary. Optimized layouts for foldable devices are provided, too. While not a major feature, we highlight it here to ensure teams are aware of its existence.
