ZXing library - intents not working - Android Q&A, Help & Troubleshooting

I am developing an app that needs to call "Barcode Scanner" using an Intent. Part of the ZXing library is the IntentIntegrator (http://code.google.com/p/zxing/sour...ion/src/com/google/zxing/integration/android/).
The IntentIntegrator allows me to use addExtra to the intent. My plan was to read whatever "extra" I added to the intent in the onActivityResult call after the barcode has been read. The problem is that the Barcode scanner application doesn`t return the extras to me after it reads the barcode.
This is my call to invoke the intent:
Code:
(...)if (v.equals(btBarcode)) {
IntentIntegrator integrator = new IntentIntegrator(this);
integrator.setTitle(getString(R.string.app_name));
integrator.addExtra(Utils.EXTRA_MODO, "add");
integrator.initiateScan();
}
And then:
Code:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
// TODO Auto-generated method stub
IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
if (scanResult != null) {
Bundle extras = intent.getExtras();
for (String key : extras.keySet())
Log.i("KEY_" + key, "value: " + extras.get(key).toString());
Log.i("extras", (extras != null) ? extras.toString() : "NULL");
String modo = (extras != null) ? extras.getString(Utils.EXTRA_MODO) : null;
Log.i("modo", (modo != null) ? modo : "NULL");
String barCode = scanResult.getContents();
if ((modo != null) && (barCode != null))
Log.d(modo, barCode);
}
}
None of the extras I set in the IntentIntegrator are being sent back to me. In the extras.keySet(), the only extras returned are from Zxing lib itself:
07-16 19:10:44.820: I/KEY_SCAN_RESULT(15500): value: 740617166453
07-16 19:10:44.825: I/KEY_SCAN_RESULT_FORMAT(15500): value: UPC_A
07-16 19:10:44.825: I/extras(15500): Bundle[{SCAN_RESULT=740617166453, SCAN_RESULT_FORMAT=UPC_A}]
07-16 19:10:44.825: I/modo(15500): NULL
Is this the way it is supposed to work (and thus I'll have to find a way to know what button of my app is calling the intent) or is it really a bug in the ZXIng library?
BTW, I've seeked help from the original developer of ZXing, Sean Owen, and he has been of absolutely no help. My original question is still in ZXing`s google group, but he doesn't seem to be making the littlest effort to understand the problem I`ve been having.
Thanks.

Never mind... I found a workaround.
My approach to the solution was to first acknowledge ZXing is buggy, so the solution wouldn't have to rely on it.
Anyhow, I never got any help from Sean Owen other than a very impolite reply. I am quite disappointed with him, because he is indeed a very intelligent man, but quite unwilling to help.
Mods, please close this thread.

Uh, what? It's not at all buggy. As was explained to you several times on the zxing mailing list, you are expecting behavior that doesn't happen in Android. You expect that when you send an Intent, that the extras you attach to the Intent always come back in the reply Intent. They don't, in any Android app. It's kind of like expecting method calls to always return their args to you -- where have you ever observed that?
Anyone who looks for the thread titled "IntentIntegrator.addExtra() not working" on the zxing discussion group on July 13 will see the thread where I helped you -- never got any help eh? oops! (I'd post the link but the forum doesn't allow it.)
I welcome anyone to read your posts, and mine. Simonetti, what's impolite is not listening to the help you were freely given by the author. You didn't understand how Android works, and that's OK. What isn't cool is having a go at me on the maliing list, and then here, pretending the project is at fault.
