CameraOfflineSession

public abstract class CameraOfflineSession
extends CameraCaptureSession

java.lang.Object
↳	android.hardware.camera2.CameraCaptureSession
	↳	android.hardware.camera2.CameraOfflineSession

A camera capture session that was switched to offline mode via successful call to CameraCaptureSession.switchToOffline.

Offline capture sessions allow clients to select a set of camera registered surfaces that support offline mode. After a successful offline mode switch all non-repeating pending requests on those surfaces will continue to be processed by the camera stack even if clients close the corresponding camera device.

Offline capture session instances will replace the previously active capture session arguments in all capture callbacks after CameraCaptureSession.switchToOffline completes.

Processing of pending offline capture requests will begin only after the offline session moves to ready state which will be indicated by the CameraOfflineSessionCallback.onReady callback.

In contrast to a regular CameraCaptureSession an offline capture session will not accept any further capture requests. Besides CameraOfflineSession.close all remaining methods will throw UnsupportedOperationException and are not supported.
