Building Camera Apps on Android Today
summary
Covers three concrete approaches: fire an intent for quick profile/photo capture; drop in a library like Photoapparat or CameraView for an embeddable UI; or implement native APIs. Walks through Camera2’s full flow (TextureView/SurfaceView, CameraManager, ImageReader, CaptureSession, repeating requests) and Camera1 fallback because you can “miss out on 22%” of devices. Shows raw capture saved as DNG, GPU-accelerated filters via GPUImage, face detection flags, and recommends checking hardware levels and using server-side toggles for flaky device features.
