Requires API Level 9. The library uses Camera 1 API on API Level 9-20 and Camera2 on 21 and above.
API Level | Camera API | Preview View |
---|---|---|
9-13 | Camera1 | SurfaceView |
14-20 | Camera1 | TextureView |
21-23 | Camera2 | TextureView |
24 | Camera2 | SurfaceView |
- Camera preview by placing it in a layout XML (and calling the start method)
- Configuration by attributes
- Aspect ratio (app:aspectRatio)
- Auto-focus (app:autoFocus)
- Flash (app:flash)
