Camera2 API and beyond
summary
Camera2 requires managing many low-level pieces so the demo builds a from-scratch sample (forked from Google) that adds manual focus and white balance controls, an explicit state machine for preview→waiting-lock→pre-capture→capture to avoid spaghetti, and an OpenGL filter pipeline that saves filtered images via ImageReader. It explains the three-step preview-size pick (rotate, pick supported sizes, fit view), shows seven callbacks you must handle, and tests only on Pixel 2 and Pixel 3 so device quirks remain.
