Why use Semaphore ?

[zondaOf2012]

I thought it would do no good.

At least, in the CameraDevice.StateCallback add this:

      @Override
        public void onClosed(@NonNull CameraDevice camera) {
            Log.i("TAG", "CameraDevice.StateCallback onClosed");
            super.onClosed(camera);
            mCameraOpenCloseLock.release();
            mCameraDevice = null;
        }
