" summary

A practical introduction to Android Camera2 API with a full sample app demonstrating a state-machine implementation of the 7-step open/request/session/capture/close flow. Covers using TextureView, ImageReader, MediaRecorder and RenderScript, shows autofocus lock/unlock, repeating preview requests and saving frames, and discusses Camera2 features (per-frame metadata, RAW/multi-exposure) while advising Camera1 is still appropriate for most client apps today and Camera2 suits tightly integrated UX on Lollipop+ devices.
