活动上的FLAG_NOT_FOCUSABLE

Question

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE);
    }
}

如果我按返回按钮，应用程序将在10-15秒内特技。在日志中写：

和应用程序崩溃。

我正在做类似AppLocker的事情。我希望当按下按钮时，此活动后面的活动（应用程序）关闭，而activity我的另一个应用程序活动后面的活动（应用程序）关闭。

任何实现此功能的方法，无需使用FLAG_NOT_FOCUSABLE。怎么做的？

我忘记关闭主题，但当我看到需要阻止的应用程序时，找到了另一种方法来阻止其他人的活动，只需启动我自己的活动
