私は偶然これを発見しました。クイズゲームがあり、正解、不正解のポップアップがあり、ゲーム終了後に結果のポップアップが表示されます。しかし、今日、ゲームの途中で戻るボタンを押してホーム画面（ゲームのホーム画面ではなく、OSのホーム画面）に戻りましたが、他のすべてのAndroidアプリと同様に、ゲームはまだバックグラウンドにありました。数秒後、間違った答えが表示されました。:) 時間切れで、自動的に答えが間違っていました。その後、最終結果のポップアップが続きました。では、戻るボタンを押したときにそのアクティビティを強制終了するにはどうすればよいですか? 皆さんが私のコードを必要としているかどうかはわかりませんが、念のために私のゲーム アクティビティを以下に示します。

これをコードに配置しようとしましたが、うまくいきませんでした:
@Override
public void onBackPressed() {
super.onBackPressed();
this.finish();
}
これも試しましたが、うまくいきませんでした：
@Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if ((keyCode == KeyEvent.KEYCODE_BACK))
{
finish();
}
return super.onKeyDown(keyCode, event);
}
