Zxing导致app停止退出

Question

I'm trying to add zxing as library to my android app - it must be offline so using Intent to outside app is bad as many people wouldn't have bar code scanner. I have Zxing as library, name is "zxingLib", and in my app "IntentIntegrator" and "IntentResult" + core.jar added.

In my app I call zxing by button:

public void scanNow(View view){

    IntentIntegrator integrator = new IntentIntegrator(this);
    integrator.initiateScan();
}

and to obtain result:

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
      IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
      if (scanResult != null) {
          intent.putExtra("com.tajchert.kolejrogowska.SCAN.SCAN_MODE", "QR_CODE_MODE");
          String contents = intent.getStringExtra("SCAN_RESULT");
          String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
          Toast toast = Toast.makeText(this, "Content:" + contents + " Format:" + format , Toast.LENGTH_LONG);
          toast.setGravity(Gravity.TOP, 25, 400);
          toast.show();
      }
    }

After pressing it show messege to install Barcode reader (form google play) - what I'm doing wrong? But If I already have barcode on my phone it stop (app&barcode reader). Log cat:

Any idea what is couse of that error? In one example I saw that my activity should extends ActivityCapture insted of Activity but if I do so eclipse mark that as an error.

Answer 1

I'm trying to add zxing as library to my android app

The ZXing team does not support this, last I checked.

it must be offline so using Intent to outside app is bad as many people wouldn't have bar code scanner

Presumably, they are online when they install your app. Hence, presumably they can be online when they install Barcode Scanner.

and in my app "IntentIntegrator" and "IntentResult" + core.jar added.

IntentIntegrator is for integrating with the Barcode Scanner app . You said that you do not want to integrate with the Barcode Scanner app.

After pressing it show messege to install Barcode reader (form google play) - what I'm doing wrong?

You are using IntentIntegrator , which is attempting to integrate with the Barcode Scanner app.

Any idea what is couse of that error?

That would appear to be a problem in the Barcode Scanner app. Try running Barcode Scanner from the launcher and see if it also crashes. If it does, then there is some incompatibility between Barcode Scanner and your device.
