Thanks for your reply! Here is my use case:
Activity A call Activity B with this Scanner to scan barcode. But if I try to close the activity b by using either onBackPressed() or finish(), activity B is closed but the camera is still open. getCameraSource.stop() or release() doesn't work for me too. I am so confused.
