私は単純なゲーム活動をしています。私はそれを開始し、戻るボタンを押すより。押すとfinish（）が呼び出されます。私は再びゲームを開始します。私はonCreate（）を実行してグローバル変数を再作成しますが、別のクラスからのブロードキャストを受け取ると、デバッグするときにアクティビティ$ 1と呼ばれる別のアクティビティが発生し、前のアクティビティはアクティビティ$ 0でした。 finish（）を呼び出すと、最初のものを強制的に強制終了できますか？または、すでに実行されているインスタンスを、2番目のセット変数から取得するにはどうすればよいですか？望ましくない第2の活動が開始されました
私のコードは、おかげで進歩であるいくつかのコメント

と以下の通りです。
