SpeechRecognizer throws ERROR_NO_MATCH on first li

问题:

The behavior is very similar to what is described here, but only happens when the googlequicksearchbox is in the background. I'm with Google APP 5.2.33.19.arm.

I created the SpeechRecognizer by calling

SpeechRecognizer.createSpeechRecognizer(myContext, new ComponentName("com.google.android.googlequicksearchbox", "com.google.android.voicesearch.serviceapi.GoogleRecognitionService"))

I got the following error message in Android Studio Logcat

GoogleRecognitionServic﹕ #startListening [es-MX]

GoogleSpeechRecognition﹕ onError No match

Here is the entire messages from the speech recognizer. There is also an ERROR_CLIENT near finish. Another thing is there is no onRmsChanged call when this happens. Usually, there are tons of this call during a normal recognition request.

googleRecognizer﹕ onError No match
googleRecognizer﹕ onReadyForSpeech
googleRecognizer﹕ onBeginningOfSpeech
googleRecognizer﹕ onPartialResults
googleRecognizer﹕ onPartialResults
googleRecognizer﹕ onPartialResults
googleRecognizer﹕ onPartialResults
googleRecognizer﹕ onPartialResults
googleRecognizer﹕ onEndOfSpeech
googleRecognizer﹕ onError Client side error
googleRecognizer﹕ onResults

You need to first understand what the SpeechRecognizer does. The SpeechRecognizer sends a "waking call" to your default speech to text application on your phone ( This can be seeing on Settings->Language and Input ). The default app wakes up, converts your speech to text and then sends it back to you onResults. In your specific case, you are explicitly calling 'google search'.

SpeechRecognizer.createSpeechRecognizer(..."com.google.android.googlequicksearchbox"...)

I would say that while 'googlequicksearchbox' is running in the background your recognizer fails to uses it (Since there can be only one instance of this action) .

Try calling a different speech to text app, and see what happens.
