Android TTS声音服务连接泄漏且已弃用

Question

我在我的课程中使用android tts只是说一条消息，例如：问题：服务连接泄漏

public class WorkTimerNotification extends ActionBarActivity implements TextToSpeech.OnInitListener {

   TextToSpeech tts;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_work_timer_notification);

    //line1
    tts = new TextToSpeech(this,this);



    @Override
public void onInit(int status) {
    //line2
    tts.setLanguage(Locale.US);

    //line3
    tts.speak("Text to say aloud", TextToSpeech.QUEUE_ADD, null);
    tts.shutdown();

}


 @Override
protected void onDestroy() {
    super.onDestroy();
    tts.shutdown();
}

第1行，我使用以下logcat泄漏了serviceConnection：

 WorkTimerNotification has leaked ServiceConnection android.speech.tts.TextToSpeech$Connection@41aee290 that was originally bound here
android.app.ServiceConnectionLeaked

我按此按钮，由于某种原因，它仍然返回哈希表。 我不知道为什么...

 int speak(CharSequence, int, Bundle, String)

我也尝试过：但是它也不起作用。

  @Override
protected void onDestroy() {
    //Close the Text to Speech Library
    if(tts!= null) {

        tts.stop();
        ttsRest.shutdown();

        Log.d(TAG, "TTS Destroyed");
    }
    super.onDestroy();
}

你不能打电话speak ，直到之后onInit被调用，将您speak的代码onInit

public class WorkTimerNotification extends ActionBarActivity implements TextToSpeech.OnInitListener {

TextToSpeech tts;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_work_timer_notification);

//line1



}

@Override
public void onInit(int status) {
//line2
tts.setLanguage(Locale.US);

//line3
tts.speak("Text to say aloud", TextToSpeech.QUEUE_ADD, null);

}



@Override
protected void onStart()
{
    super.onStart();

    tts = new TextToSpeech(this,this);
}

@Override
protected void onStop()
{
    super.onStop();
    tts.shutdown();
}
