i used this code:

qrEader = new QREader.Builder(this, surfaceView, new QRDataListener() {
            @Override public void onDetected(final String data) {
                Log.d("QREader", "Value : " + data);
                textView_qrcode_info.post(new Runnable() {
                    @Override public void run() {
                        textView_qrcode_info.setText(data);
                    }
                });
            }
        }).facing(QREader.BACK_CAM)
                .enableAutofocus(true)
                .height(800)
                .width(1100)
                .build();

        qrEader.init();
//////
@Override protected void onStart() {
        super.onStart();

        // Call in onStart
        qrEader.start();
    }

    @Override protected void onDestroy() {
        super.onDestroy();

        // Call in onDestroy
        qrEader.stop();
        qrEader.releaseAndCleanup();
    }

in my Activity

Do you have surface view in the layout and referenced in code as below ? surfaceView = (SurfaceView) findViewById(R.id.camera_view);

Everything looks fine to me. Are you using Instant Run ? Can you confirm uninstalling the app and reinstalling it without Instant run helps you or not ?

i also tested in lg g2 with android 5.0 but :| Exception thrown from receiver. java.lang.IllegalStateException: Detector processor must first be set with setProcessor in order to receive detection results. at com.google.android.gms.vision.Detector.receiveFrame(Unknown Source) at com.google.android.gms.vision.CameraSource$zzb.run(Unknown Source) at java.lang.Thread.run(Thread.java:818)

Let me do some more testing and I will update you soon.
