android - TTS-リークされたServiceConnection

Question

APPでTTSを使用しています。onPuaseメソッドの実行中に、次のコードを使用してエンジンを停止します。問題は、ホームボタンを使用してアクティビティを一時停止すると、logcatセクションに貼り付けたときにエラーが発生することです。ログ猫（アクティビティcom.example.DragDrop.PlaySeriesがServiceConnectionをリークしました）から、問題は何らかのリークが原因であることがわかりました。ただし、問題はアプリを停止したり、機能を妨害したりすることではありません。しかし、私はこの問題の深刻さとこれを回避する方法を知りたいですか？

助けてください

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();
}

とonCreateで

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);
}

このコードを持っているだけonDestroy

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

    tts.shutdown();
}

TTSオブジェクトを静的にしたときにも同様のエラーが発生しました（そのため、デバイスを回転させてもTTSは読み上げを続けます）。デバイスを回転させたときにリークがトリガーされ、画面が縦向きモードと横向きモードの間で変化しました。

エラーが以前のバージョンのAndroidを実行している一部の古いデバイスでのみ報告されたため、しばらくの間私は困惑しました。ただし、修正を発見すると、問題はすべてのデバイスとバージョンに共通していると思われますが、新しいモデルではマスクされている可能性があります。

修正は、現在の（アクティビティ）コンテキストではなく、アプリケーションコンテキストを使用してTTSオブジェクトを初期化することでした。

これが私のコードです tts = new TextToSpeech(getApplicationContext(), this);

これが、アクティビティの外部/サービス内からのTTS用のTurnKeyソリューションです...

onDestroyを使用できない場合は、読み上げが終了したときにリッスンしてから、シャットダウンしてTTSを停止します。アプリケーションコンテキストを使用して、リークを防ぎます。どうぞ。
