В сервисе произошла утечка ServiceConnection android .speech. SpeechRecognizer$Connection@2e1ecaf, которая изначально была связана здесь

Я пытаюсь запустить службу, которая однажды запустила запись звука в течение 5 секунд с помощью средства распознавания речи. Однако всякий раз, когда я запускаю службу, он вызывает метод onError в классе распознавателя речи, и как только я останавливаю службу, он выдает мне ошибку:

Утечка службы ServiceConnection android .speech . SpeechRecognizer$Connection@2e1ecaf, который изначально был связан здесь

Я перепробовал все и везде искал, но, похоже, не нашел решения. Пожалуйста, помогите.

Вот мой сервисный код, он запускается и останавливается с помощью кнопок в mainActivity.

MicrophoneService. java

Вы должны уничтожить распознаватель речи при остановке службы. 

@Override
public void onDestroy() {
    mSpeechRecognizer.destroy();
    super.onDestroy();
}
...
