问题描述
我有一个应用程序，在其中我要从main activity调用ACTION_SEND意图.一切正常，但是当我从ACTION_SEND目的返回我的主要活动时，main activity从onCreate()方法开始执行，但是我希望从onRestart()方法开始.我认为它的OS会杀死我的活动以释放空间.那么有什么方法可以使用，而不是使用Service来阻止操作系统终止我的活动?
I have an application in which I am calling ACTION_SEND intent from my main activity. Everything works fine but when I return to my main activity from ACTION_SEND intent then main activity starts its execution from onCreate() method but I want it to be started from onRestart() method.I think its bcz a OS kills my activity to free up space.So is there any way rather than using Service So that I can stop OS from killing my activity ?
推荐答案
可能.您可能自己在做些事情来破坏自己的活动(例如，在为ACTION_SEND Intent调用startActivity()之后，调用finish()).
Possibly. You might be doing something yourself to destroy your activity (e.g., calling finish() after calling startActivity() for your ACTION_SEND Intent).
不.甚至服务也可能无济于事.您可以随时以任何理由终止您的进程，包括用户决定通过任务管理器或近期任务"列表终止该过程.另外，如果用户在通过ACTION_SEND启动的任何应用中旋转屏幕或引起其他配置更改，由于配置更改，将重新创建名为startActivity()和ACTION_SEND的活动.
No. Even a service may not help. Your process can be terminated at any time, for any reason, including the user deciding to terminate it via a task manager or the recent-tasks list. Also, if the user rotates the screen or causes another configuration change while in whatever app they started via ACTION_SEND, your activity that called startActivity() with ACTION_SEND will be recreated due to the configuration change.
您不能假定将调用onRestart().通常，出于这个原因，我认为onRestart()是代码气味.
You cannot assume that onRestart() will be called. In general, I consider onRestart() to be a code smell for just this reason.
