我在我的应用程序中使用 TTS。在 onPuase 方法中，我使用以下代码来停止引擎。问题是每当我暂停活动说使用主页按钮时，我都会收到错误，因为我已粘贴在 log cat 部分。我从日志猫（活动 com.example.DragDrop.PlaySeries 已泄漏 ServiceConnection ）中了解到问题是由于某些泄漏造成的。但是，问题并没有停止我的应用程序或干扰任何功能。但我想知道这个问题的严重性以及如何避免这种情况？

请帮忙 

protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();   
    Log.i("PlaySeries", "In pause play series");
    if(tts !=null){
        Log.i("PlaySeries", "In pause play series");
        tts.stop(); 
    //  tts.shutdown();
    }
}

@Override
protected void onDestroy() {  
    //Close the Text to Speech Library
    if(tts !=null){
        Log.i("PlaySeries", "In pause play series");
        tts.stop(); 
        tts.shutdown();
    }
    super.onDestroy();
}

并在 onCreate

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

    setContentView(R.layout.series);

    tts = new TextToSpeech(this,this);
}

只要有这个代码onDestroy 

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

    tts.shutdown();
}

当我将 TTS 对象设为静态时，我遇到了类似的错误（因此即使设备旋转，TTS 也会继续说话）。当设备旋转时触发泄漏，因此屏幕在纵向和横向模式之间切换。

有一段时间我很困惑，因为该错误仅在一些运行早期版本 Android 的旧设备上报告。但是，一旦我发现了修复程序，我怀疑该问题对所有设备和版本都很常见，但可能在较新的型号上被掩盖了。

修复是用应用程序上下文初始化 TTS 对象，而不是当前（活动）上下文。

这是我的代码 tts = new TextToSpeech(getApplicationContext(), this);

这是我在活动外部/服务中的 TTS 交钥匙解决方案......

如果你不能使用 onDestroy，只需听它说完然后关闭并停止 TTS。使用应用程序上下文来防止泄漏。给你。

    import android.content.Context;
import android.os.Build;
import android.speech.tts.TextToSpeech;
import android.speech.tts.UtteranceProgressListener;
import android.util.Log;
