Generated link from QR code should be directed through browser

I have already created a QR scanner android application. What I need is that if I scan a QR code and if it generates a link, so the app should automatically open that link through the browser. Any help will be appreciated. Thank You!!

Down below is my QR scanner code :

public class VehicleReaderActivity extends AppCompatActivity implements ZXingScannerView.ResultHandler  {

private ZXingScannerView mScannerView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setTitle("SCAN QR CODE");
    mScannerView = new ZXingScannerView(this);
    setContentView(mScannerView);
    mScannerView.setResultHandler(this);
    mScannerView.startCamera();
}

@Override
protected void onPause() {
    super.onPause();
    mScannerView.stopCamera();
}

@Override
public void handleResult(Result result) {
    // Do anything with result here
    Log.w("handleResult", result.getText());

    // Now direct the generated link to the browser //
    Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://" + result.getText()));
    startActivity(browserIntent);

    //Resume scanning
    //mScannerView.resumeCameraPreview(this);
}
}

If you have already implemented a "QR scanner" then check, there must be a callback method where you receive the returned text from the "Scanner".
Inside that callback method, fire an intent to open the browser with a specific url like shown below: 

Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url)); // here ulr is the one that you get from scanner
startActivity(i);

I hope it helps.

When you get the callback of QR code generated

Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));
startActivity(browserIntent);

To open that link in browser

As for the missing "http://" I'd just do something like this:

if (!url.startsWith("http://") && !url.startsWith("https://"))
url = "http://" + url;

To validate the URL

URLUtil.isValidUrl(url)
