Error Android Mobile Vision for barcode scanning

I am trying to implement the second part of the tutorial in this link:

http://code.tutsplus.com/tutorials/reading-qr-codes-using-the-mobile-vision-api--cms-24680

I am getting the error:

BarcodeDetector has private access at..

ERROR IMAGE HERE

Any idea why?

public class ScanActivity extends Activity {
SurfaceView cameraView;
TextView barCodeInfo;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_scan);
        cameraView = (SurfaceView) findViewById(R.id.camera_view);
        barCodeInfo = (TextView) findViewById(R.id.code_info);

        BarcodeDetector  barcodeDetector = new BarcodeDetector().Builder(this).setBarcodeFormats(Barcode.QR_CODE)
                .build();
    }
}

The problem is that you are trying to access BarcodeDetector and its constructor is private BarcodeDetector(). BarcodeDetector uses Builder Pattern.

"Builder pattern builds a complex object using simple objects and using a step by step approach." http://www.tutorialspoint.com/design_pattern/builder_pattern.htm

so change to the code below :

BarcodeDetector  barcodeDetector = new BarcodeDetector.Builder(this).setBarcodeFormats(Barcode.QR_CODE)
            .build();
