" summary

Explains how mobile camera work flows from sensor to app: separate preview, photo, and video pipelines, one configuration in, one frame out, and templates for common configs; details API choices Camera1 vs Camera2 and legacy quirks, trade-offs like substituting fast preview frames for slow JPEGs and TakePicture ~400ms on high-end phones, plus engineering tactics—operation queue, remote device configs, mocking frames or camera for tests, ImageReader and GPU paths, and the new Multi‑Camera API in Android P to access logical and physical streams.
