问题描述

如果我的应用程序遇到特定的错误，我想结束我的应用程序来说，不会残留在系统中的任何痕​​迹。我已经看到很多线程关于这个主题，特别是这两个。

If my app encounters a particular error, I want to end my app without any trace of it remaining in the system. I have already seen many threads on this topic, specially these two.

答案是伟大的，但所提出的解决方案是过于繁琐和/或不必要的复杂。

The answers are great but the proposed solutions are too tedious and/or unnecessarily complex.

推荐答案

以从第一篇文章以上尼尔Traft的回答一个提示，我发现了这样的情况下的完美解决方案。

Taking a cue from Neil Traft's answer in the first post above, I have found a perfect solution for such scenarios.

System.exit（0）或android.os.Process.killProcess（android.os.Process.myPid（）），双方似乎如果你在应用程序的backstack只有一个活动的工作，其他的Andr​​oid刚刚重新推出你的应用程序推在（上 - 1）活动的前景，也许是因为Android的假设用户与应用程序交互，它突然死机，所以他应该继续与它交互

System.exit(0) or android.os.Process.killProcess(android.os.Process.myPid()) both seem to work if you have only one Activity in the app's backstack, else Android just relaunches your app pushing the (top - 1) Activity to the foreground, maybe because Android assumes that the user was interacting with the app and it suddenly "crashed", so he should continue interacting with it.

所以，我的解决办法是先用Activity.moveTaskToBack（）发送应用程序到后台，然后调用这两种方法之上。

So, my solution is to first send the app into background using Activity.moveTaskToBack() and then invoke either of the two methods above.

private void terminateApp() {       

    // TODO: Don't forget to clean up your background threads, services, etc. 

    // send the app into background, otherwise Android will relaunch the app process if you have multiple Activities in your backstack.
    moveTaskToBack(true);

    // kill everything running in this process.
    System.exit(-1); // or you can use android.os.Process.killProcess(android.os.Process.myPid());
}

我看不出有什么问题，这种方法不同的是它违背了Android的设计原则......虽然这完美的作品，当你真的需要它。

I don't see any problem with this approach except that it goes against Android design principles... though this works perfectly when you really, really need it.
