Add core-2.2.jar & android-integration-2.2.jar into library in compile & gradle (if has). Then apply the code below

IntentIntegrator integrator = new IntentIntegrator(yourActivity);
integrator.initiateScan();
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
  IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
  if (scanResult != null) {
    // handle scan result
  }
  // else continue with any other code you need in the method
  ...
}
