Getting to know CameraX
summary
CameraX claims 70% fewer lines of code than Camera2 and runs back to L (backwards compatible to L, covering >90% of devices), fixes flash and camera‑switch crashes via device test farm, and exposes three concrete use cases: preview, image analysis, image capture. It provides lifecycle binding, imageProxy with rotationDegrees for analyzers, CameraControl APIs for tap‑to‑focus and pinch/slider zoom, vendor extensions (HDR/portrait) when available, and a GitHub sample that implements center‑crop preview but requires manual application of the same transforms to saved photos.
