* which is called by the camera service when a physical camera backing a
|
|
* logical multi-camera becomes unavailable or available again.
|
|
* - The function returns a vector of the newer version of CameraStatusAndId
|
|
* which contains unavailable physical cameras if the specified camera is a
|
|
* logical multi-camera.
|
|
*
|
|
* @param listener the listener interface to be added. The cameraserver will
|
|
* call callbacks on this interface when a camera device's status
|
|
* changes.

|

* @return statuses a list of CameraStatusAndIds which stores the deviceIds,
|
|
* their corresponding statuses, and the unavailable physical camera Ids
