Microsoft Cognitive Speech Service - Android

Question

Я использую Microsoft Cognitive Services - распознавание речи в приложении для Android. Все работает нормально, когда код находится в моем основном действии, но когда я хочу переместить часть, соответствующую распознаванию речи, новому классу, она выдает ошибку.

Вот примеры кода:

В основной деятельности

int m_waitSeconds = 0;

FinalResponseStatus isReceivedResponse = FinalResponseStatus.NotReceived; 
Boolean speechIntent = false;

Вы можете очистить Посмотрим, что это в основном тот же код, но он дает мне эту ошибку в функции onError после того, как я вызываю this.micClient.startMicAndRecognition(); :

Error code: LoginFailed -1910505470 

Answer 1

Я решил проблему. я получаю неправильный первичный ключ в этой строке кода:

public String getPrimaryKey() { 
    return Integer.toString(R.string.primaryKey); 
} 

Это происходит потому, что первичный ключ слишком долго, чтобы быть считаны процессором как целое, то преобразованного в строку. Я должен был получить первичный ключ от основного действия через getString (R.string.primaryKey) затем передать его как параметр конструктору класса SpeechRecognition.
