EmbeddedPhotoPickerSession
| android.widget.photopicker.EmbeddedPhotoPickerSession |
Class that holds the embedded photopicker view wrapped in
SurfaceControlViewHost.SurfacePackage that can be embedded by the caller in their
view hierarchy by placing it in a SurfaceView via its
SurfaceView.setChildSurfacePackage api.
Callers of EmbeddedPhotoPickerProvider.openSession will asynchronously receive instance
of this class from the service upon its successful execution via
EmbeddedPhotoPickerClient.onSessionOpened callback.
Instance of this class can be then used by callers to notify PhotoPicker about different events for service to act upon them.
When a session is no longer being used, it should be closed by callers to help system release the resources.
