Remarks
Name under which an activity handling #INTENT_ACTION_STILL_IMAGE_CAMERA or #INTENT_ACTION_STILL_IMAGE_CAMERA_SECURE publishes the service name for its prewarm service.
This meta-data should reference the fully qualified class name of the prewarm service extending CameraPrewarmService.
The prewarm service will get bound and receive a prewarm signal CameraPrewarmService#onPrewarm() when a camera launch intent fire might be imminent. An application implementing a prewarm service should do the absolute minimum amount of work to initialize the camera in order to reduce startup time in likely case that shortly after a camera launch intent would be sent.
