CameraX Workshop
summary
Builds a camera app from scratch using Jetpack CameraX with live preview, photo capture that writes files and logs the path, and a frame image analysis pipeline that computes luminosity and skips frames when timestamps don’t advance. Requires adding CameraX core + camera2 module deps, runtime camera permission, and a TextureView wake-up hack (remove and readd) to attach CameraX surfaces. Notes that Google runs >1,000 devices in a test lab and the emulator exhibits an emulator single-threaded slowdown for image analysis.
