Check your permission on Manifest file. If you launched the application on android 6.0+, you should use permission request like below;

 // Here, thisActivity is the current activity
    if (ContextCompat.checkSelfPermission(thisActivity,
                     Manifest.permission.CAMERA)
            != PackageManager.PERMISSION_GRANTED) {

        // Should we show an explanation?
        if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
                 Manifest.permission.CAMERA)) {

            // Show an explanation to the user *asynchronously* -- don't block
            // this thread waiting for the user's response! After the user
            // sees the explanation, try again to request the permission.

        } else {

            // No explanation needed, we can request the permission.

            ActivityCompat.requestPermissions(thisActivity,
                    new String[]{ Manifest.permission.CAMERA},
                    MY_PERMISSIONS_REQUEST_CAMERA);

            // MY_PERMISSIONS_REQUEST_CAMERA is an
            // app-defined int constant. The callback method gets the
            // result of the request.
        }
    }

I'm the author of the library and I just released a new 2.0 with several improvements, try to update to the latest version and see if the issue is solved.

Please check it out here: https://github.com/dlazaro66/QRCodeReaderView and if it doesn't work, open an issue there.
