这标志是有正是这个原因。这样做是为了检查并确保您的应用程序处理的活动遭到破坏。你不能覆盖它，因为在现实生活中，可能如果设备内存不足，甚至发生没有该标志。您需要code事情要处理，这种情况下不覆盖它。

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.
