在我的应用中，我创建了一项活动。它在启动时创建服务。活动中有一个按钮。当它被按下时，它触发服务使用TTS重复以10秒的间隔说出一个句子。我可以听到重复的句子。然后我按回家隐藏活动，然后关闭屏幕。我还能听到这句话。但大约半小时后，我再也听不到了。然后我看看logcat：

有人能向我解释发生了什么吗？提前谢谢。
对于tts config in serivce：
@SuppressWarnings("deprecation")
@Override
public void onInit(int status) {
// TODO Auto-generated method stub
if(status == TextToSpeech.SUCCESS)
{
setTts(_tts);
}
}
@SuppressWarnings("deprecation")
public void setTts(TextToSpeech tts)
{
if (Build.VERSION.SDK_INT >= 15)
{
tts.setOnUtteranceProgressListener(new UtteranceProgressListener()
{
@Override
public void onDone(String utteranceId)
{
onDoneSpeaking(utteranceId);
}
@Override
public void onError(String utteranceId)
{
}
@Override
public void onStart(String utteranceId)
{
}
});
}
else
{
tts.setOnUtteranceCompletedListener(this);
}
}
