From: Shuzhen Wang The ID of the active physical camera that's backing the logical camera. All camera
* streams and metadata that are not physical camera specific will be originating from this
- * physical camera. This must be one of valid physical IDs advertised in the physicalIds
- * static tag.
For a logical camera made up of physical cameras where each camera's lenses have * different characteristics, the camera device may choose to switch between the physical * cameras when application changes FOCAL_LENGTH or SCALER_CROP_REGION. * At the time of lens switch, this result metadata reflects the new active physical camera * ID.
+ *This key will be available if the camera device advertises this key via {@link ACAMERA_REQUEST_AVAILABLE_RESULT_KEYS }. + * When available, this must be one of valid physical IDs backing this logical multi-camera. + * If this key is not available for a logical multi-camera, the camera device implementation + * may still switch between different active physical cameras based on use case, but the + * current active physical camera information won't be available to the application.
