Android Google Речь в текст ApiStreamObserver показывает «Необнаруженное исключение в SynchronizationContext. Panic! ошибка?

Question

Я использую Google speech to text api из моего приложения для перевода.Здесь я инициализирую ApiStreamObserver для StreamingRecognizeResponse, это выдает какую-то ошибку.Код ниже,

Инициализировать SpeechClient как,

   @SuppressLint("StaticFieldLeak")
private void InitValue() {
    new AsyncTask<Void, Void, Void>() {
        @Override
        protected Void doInBackground(Void... params) {
            try {
                final InputStream stream = getResources().openRawResource(R.raw.transcribeapi);
                ServiceAccountCredentials credentials = ServiceAccountCredentials.fromStream(stream);
               mSpeechClient = SpeechClient.create(SpeechSettings.newBuilder()
                        .setCredentialsProvider(fixedCredentialsProvider)
                        .build());
                GetAudioPermission();
                initialized = true;
            } catch (IOException e) {
                e.printStackTrace();
            }
            return null;
        }
    }.execute();
}

StreamingRecognizeClient

ApiStreamObserver<StreamingRecognizeRequest> mRequestObserver;
  mRequestObserver= mSpeechClient.streamingRecognizeCallable().bidiStreamingCall(new ApiStreamObserver<StreamingRecognizeResponse>() {
        @Override
        public void onNext(StreamingRecognizeResponse response) {
            Log.d(TAG, "onNext: ");
           /* int numOfResults = response.getResultsCount();
            if( numOfResults > 0 ){
                for (int i=0;i<numOfResults;i++){
                    Log.d(TAG, "onNext: "+response.getResults(i).getAlternatives(i));
                }
            }*/

        }
        @Override
        public void onError(Throwable t) {
            Log.d(TAG, "onError: "+t.getMessage());
        }

        @Override
        public void onCompleted() {
            Log.d(TAG, "onCompleted: ");
        }
    });

сообщение об исключении;

Еще два дня я работаю над этим проектом, нигде нет примеров. Доступны только примеры kotlin.

Пожалуйста, кто-нибудь поможет мне ..

Заранее спасибо ...
