A single, stand-alone Android app that showcases the Camera2 and CameraX APIs through a catalog of small, self-contained, Compose-first samples. Each sample focuses on one feature and reuses a shared camera-scaffolding layer, so adding a new sample means writing the feature — not the boilerplate.
The home catalog in the "Console" theme — a violet accent, monospace metadata, a bordered featured card, and a dense 2-column grid. The filter pills narrow the catalog by category, and samples are grouped CameraX-first, Camera2 below.
- Clone the repository.
- Open it in a recent Android Studio.
- Run the
appconfiguration on a device or emulator. Camera-dependent samples (extensions, slow-motion, ML) behave best on a physical device; emulators with a virtual camera cover the basics.
No Firebase / google-services.json is required.
Filter the catalog by category (Images / Video / ML / Graphics / Extensions / Controls) on the home screen. Within each view, CameraX samples are listed first and Camera2 below.
