SDK Architecture

Key Components

UI Module

CameraController
- The core engine that manages the entire lifecycle of the camera and detection session.
- Created with a license (LicenseInfo) and controlled via initializeCamera() / startDetection() and similar methods.
- Detection events are delivered through PetnowCameraDetectionListenerV2, and state through getState() (StateFlow).
CameraView
- A FrameLayout widget that renders the camera preview and the default tracking UI.
- Connect it to a controller with cameraView.controller = controller.
PetnowCameraFragment (legacy)
- A Fragment-hosting approach. For new integrations, we recommend CameraView + CameraController. See Fragment Approach (legacy).
