SpeechRecognizer throws onError on the first listening

Question

In the Android 5 I faced with strange problem. The first call to the startListening of SpeechRecognizer results to the onError with error code 7 (ERROR_

Answer 1

I had the same problem but I couldn't find a workaround, so I ended up just calling return inside onError if the time between startListening and onError is unreasonably short.

protected long mSpeechRecognizerStartListeningTime = 0;

protected synchronized void speechRecognizerStartListening(Intent intent) {
    if (mSpeechRecognizer != null) {
        this.mSpeechRecognizerStartListeningTime = System.currentTimeMillis();
        RLog.d(this, "speechRecognizerStartListening");
        this.mSpeechRecognizer.startListening(intent);
    }
}
...
@Override
public synchronized void onError(int error) {
    RLog.i(this, this.hashCode() + " - onError:" + error);

// Sometime onError will get called after onResults so we keep a boolean to ignore error also
    if (mSuccess) {
        RLog.w(this, "Already success, ignoring error");
        return;
    }

    long duration = System.currentTimeMillis() - mSpeechRecognizerStartListeningTime;
    if (duration < 500 && error == SpeechRecognizer.ERROR_NO_MATCH) {
        RLog.w(this, "Doesn't seem like the system tried to listen at all. duration = " + duration + "ms. This might be a bug with onError and startListening methods of SpeechRecognizer");
        RLog.w(this, "Going to ignore the error");
        return;
    }

// -- actual error handing code goes here.
}
