推荐答案

之所以出现这个标志，正是因为这个原因.这个想法是检查并确保您的应用程序处理其被销毁的活动.您无法覆盖它，因为在现实世界中，如果设备内存不足，即使没有该标志也可能发生.您需要编写代码来处理这种情况，而不是覆盖它.

That flag is there for exactly this reason. The idea is to check and make sure your app handles its activities being destroyed. You can't override it because in the real world it might happen even without that flag if the device is low on memory. You need to code things to handle this case not override it.
