onCameraAvailable()

}

onImageCallback()

void onImageCallback	(	void *	ctx,
		AImageReader *	reader
	)

ImageReader listener: called by AImageReader for every frame captured We pass the event to ImageReader class, so it could do some housekeeping about the loaded queue. For example, we could keep a counter to track how many buffers are full and idle in the queue. If camera almost has no buffer to capture we could release ( skip ) some frames by AImageReader_getNextImage() and AImageReader_delete().
