  var intent = Ti.Android.createIntent({
    action: "com.google.zxing.client.android.SCAN"
  });
  intent.putExtra("SCAN_MODE", "QR_SCAN_MODE");
  var activity = Ti.Android.currentActivity;
  activity.startActivityForResult(intent, function(e) {
    if (e.resultCode == Ti.Android.RESULT_OK) {
      var contents = e.intent.getStringExtra("SCAN_RESULT");
      var format = e.intent.getStringExtra("SCAN_RESULT_FORMAT");
      Ti.UI.createNotification({
        message: "Contents: " + contents + ", Format: " + format
      }).show();
    } else if (e.resultCode == Ti.Android.RESULT_CANCELED) {
      Ti.UI.createNotification({
        message: "Scan canceled!"
