I have solved this issue by doing the following:

1 - Make the Visibility of QRCodeReaderView to GONE in XML. 2- For Android M: request for camera permission. then in onRequestPermissionsResult() show up the QRCodeReaderView to VISIBLE. and add the view properties mydecoderview = (QRCodeReaderView) mainLayout.findViewById(R.id.qrdecoderview); assert mydecoderview != null; mydecoderview.setOnQRCodeReadListener(this); mydecoderview.setAutofocusInterval(2000L); mydecoderview.setBackCamera(); mydecoderview.setVisibility(View.VISIBLE); mydecoderview.startCamera();

This really should be handled by the component.
