Android Speech Recognition API does not work in Android 7 Nougat

Question

I am using the android.speech.SpeechRecognizer API for speech.

I works great in Android 4-5,

In Android 6 it now has a bunch of bugs, like the chime that occurs

Answer 1

My code works fine on Nexus5x(Nougat) and Nexus9(Nougat)

try and show logcat.

SpeechRecognizer mGoogleSr;

void initGoogleSr(Context context) {
    mGoogleSr = SpeechRecognizer.createSpeechRecognizer(context);
    mGoogleSr.setRecognitionListener(new GoogleSrListener());
}

void startGoogleSr() {
    if (mGoogleSr != null) {
        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, getPackageName());
        intent.putExtra(RecognizerIntent.EXTRA_PARTIAL_RESULTS, true);
        mGoogleSr.startListening(intent);
    }
}
void cancelRecognizing() {
    if (mGoogleSr != null) {
        mGoogleSr.cancel();
    }
}

public class GoogleSrListener implements RecognitionListener {
    String lastPartialText;

    @Override

        Log.v(TAG, ">>> onReadyForSpeech");

permissions in manifest(maybe redundant):

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
