SpeechRecognizer onResults not firing

Question

I have a fairly strange problem. I have a android app for which I'm adding speech recognition using the SpeechRecognizer class. I've created class implementing RecognitionListener, which just prints a log message for each event. And everything seems fine. onReadyForSpeech gets fired, onBeginningOfSpeech gets fired and onEndOfSpeech gets fired.

One important event doesn't get fired though, onResults :p

So in summery, everything seems fine, no exceptions are thrown, and I get events telling me that it successfully have started and stopped listening. Am I missing some extra for the intent which tells the SpeechRecognizer that it needs to send results to onResults or something like that?

I set up the intent as follows

    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, getClass().getPackage().getName());
    intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 5);

the SpeechRecognizer is done as

    SpeechRecognizer speech = SpeechRecognizer.createSpeechRecognizer(this);
    speech.setRecognitionListener(this);

And I start listening with

speech.startListening(intent);

onError wasn't called, that was the odd part. I isolated it to a network issue, since it works if i turn off wireless and use 3G. If i turn off 3G as well (no network at all) onError fires. Tried another wireless and it works on there as well, but at my work wireless, it doesn't work and does not call onError. — JustDanyul

I had exactly the problem as stated in the problem statement. I have two Voice Recognition Services available (Google and one more). I was going wrong inside an inner class:

private final Handler handler = new Handler();
private final Runnable stopListeningRunnable = new Runnable() {
                @Override
                public void run() {
                    speechRecognizer.stopListening(); 
                }
            };

Instead of writing this in the method which was using it, I had put it at the beginning of an inner class.

This was stopping the call to onResults. As soon as I inlined this in the method which actually used it, onResults worked fine.

Hope this helps you.. :)
