こんにちは、オージー ブロークという私のキャラクターの響板を作成しました。響板には 30 個のボタンと 30 個のメディア プレーヤーが含まれています。最初はすべてのボタンに 1 つのメディアプレーヤーを使用していましたが、約 20 回ランダムに押すと、最終的にサウンドの再生が停止しました。そこで、私が使用した元のサウンドボード テンプレートで使用されていたように、サウンドごとに個別の mediaplayer オブジェクトを使用することにしました。これは問題なく機能し、一日中ボタンを押してサウンドを適切に動作させることができました..しかし、私が抱えている問題は、アクティビティがバックグラウンドに送信され、数秒後に再び戻されると、ボタンを押すとアプリがクラッシュすることです..すべてのプレーヤーを準備するために onResume メソッドを作成しようとしましたが、これによりアプリが最初からクラッシュしました..

アクティビティにメソッドを実装onResume()し、そこでメディアプレーヤーオブジェクトを再作成する必要があります。

public void onResume()  {
  super.onResume();

 // ...

 beer1 = MediaPlayer.create(this, R.raw.beer1);
 beer2 = MediaPlayer.create(this, R.raw.beer2);
 beer3 = MediaPlayer.create(this, R.raw.beer3);

 // ...
}

アクティビティのライフサイクルについて詳しくは、http： //developer.android.com/training/basics/activity-lifecycle/index.htmlをご覧ください。
