私のアプリケーションが稼働しているとしましょう。次に、デバイスのホーム画面に移動します。Settings>>Applications>>ManageApplicationsに移動し、自分のアプリケーションを選択して、 を押しForce stopます。
Activity次にアプリケーションを開いたときに呼び出されるメソッドはどれですか? 自分自身をチェックしていないために攻撃される前に、私は自分の、およびメソッドに多数のLogステートメントを持っていますが、アプリケーションを再度開いたときに文字通りどれも表示されません。onCreateonStartonResumeLogCat
Force stop私のアプリケーションがどの状態に置かれるかについての答えがわかっているが、欠落しているLogステートメントが意味をなさない場合は、共有してください. プログラムの場所が見つからない以外に、別の問題があると思いますForce stop。
