Remarks
A callback for camera flash torch modes becoming unavailable, disabled, or enabled.
The torch mode becomes unavailable when the camera device it belongs to becomes unavailable or other camera resources it needs become busy due to other higher priority camera activities. The torch mode becomes disabled when it was turned off or when the camera device it belongs to is no longer in use and other camera resources it needs are no longer busy. A camera's torch mode is turned off when an application calls #setTorchMode to turn off the camera's torch mode, or when an application turns on another camera's torch mode if keeping multiple torch modes on simultaneously is not supported. The torch mode becomes enabled when it is turned on via #setTorchMode.
The torch mode is available to set via #setTorchMode only when it's in a disabled or enabled state.
Extend this callback and pass an instance of the subclass to CameraManager#registerTorchCallback to be notified of such status changes.
