CameraKit/camerakit-android
Camerakit Android
Camerakit-android is a library and API wrapper that provides a consistent interface for photo and video capture across Android Camera 1 and 2 APIs. It functions as a media capture library that standardizes hardware access and provides a unified system for recording images and video across different operating system versions.
The project includes a camera preview component that automatically scales and crops camera output to fit custom view dimensions. It also provides a camera control toolkit for managing continuous autofocus, tap-to-focus interactions, and pinch-to-zoom gestures.
The toolkit covers broad capability areas including camera hardware control, mobile media capture, and automated camera permission management to handle the system request flow for hardware access.
Features
- Mobile Media Capture - Provides a consistent hardware-level recording interface for photos and videos on mobile devices.
- Live Capture and Recording - Implements a system for recording live images and video using shared preview sessions and diverse capture methods.
- Android Camera Integrations - Provides a consistent interface for building photo and video capture features across different Android hardware versions.
- Camera API Implementations - Acts as a wrapper that simplifies interaction with Android Camera 1 and 2 APIs through consistent architectural patterns.
- Hardware Permission Management - Provides utilities for requesting and evaluating system-level hardware permissions for the device camera.
- Media Capture Libraries - Provides a set of tools for recording images and video with automated handling of permissions and OS versions.
- Hardware Control Interfaces - Maps high-level focus and zoom requests to device-specific hardware commands through a standardized control interface.
- Android Permission Management - Manages the system request flow for camera access and handles Android runtime permissions.
- Asynchronous Permission Flows - Implements asynchronous callback chains to manage Android system camera permission request flows.
- Cross-Version API Abstractions - Provides a unified interface layer that normalizes API differences between Android Camera 1 and Camera 2 APIs.
- Camera Interaction Controllers - Implements interactive handlers that map user inputs like pinch and tap to camera focus and zoom.
- Concurrent Capture Sessions - Maintains shared hardware sessions that route camera data to both real-time previews and recording sinks.
- Camera Hardware Controls - Provides programmatic control over camera hardware, specifically for managing autofocus and zoom.
- Hardware Capability Resolutions - Automatically determines the optimal sensor resolution and aspect ratio based on the available hardware capabilities.
- Camera Sensor Scaling - Calculates crop and scale factors to map the raw camera sensor output to any custom UI view dimensions.
- Camera Preview Embeddings - Renders live camera previews within custom view hierarchies using SurfaceView or TextureView.
- Preview Dimension Scaling - Provides logic for adjusting the size and aspect ratio of a camera preview to fit host containers.
- Camera Focus and Zoom Gestures - Provides tools for managing continuous autofocus, tap-to-focus interactions, and pinch-to-zoom gestures.
