如何重新启动从内部应用程序的Andr​​oid应用 [英] How to restart android application from within application

问题描述

我有一个要求重新启动，当用户更改preference应用。清除栈犯规帮助我，因为这并不取消后端服务电话。我想杀死应用程序本身。我使用

I have a requirement to restart the application when the user changes a preference. Clearing the stack doesnt help me since this doesnt cancel the backend service calls. I want to kill the application process itself. I am using

Process.killProcess(Process.myPid());

和它为我杀的应用程序。但是，我需要的是重新启动应用程序。是指杀死进程，引发新工艺，使该应用程序重新开始一次。

and it works for me to kill the application. But what i need is to restart the application. Means kill the process and trigger a new process so the application start fresh once again.

有没有办法做到这一点？

Is there a way to do this?

在此先感谢。

推荐答案

这是不是其中之一或许应该尝试做一个测试环境之外。

This is not something which one should probably attempt to do outside of a testing environment.

这是说，两个思路：

1）在不久的将来，将有一段时间报警，然后杀了你的流程

1) Set an alarm for some time in the very near future and then kill your process

2）启动其他的东西（也许是小本机进程或shell脚本），将检测到你的死亡，并通过一个意图重新启动您

2) Start up something else (perhaps a small native process or shell script) that will detect your death and restart you via an intent

您也可以尝试发射了一个意图，开始自己，然后迅速凋零，但是这听起来像依赖于实现一个潜在的竞争状态。如果你抓住了粘合剂FD出来的/ proc，并在当地code做了恶事，你也许能断火意图以这样的方式从读写控制返回您的应用程序崩溃...

You could also try firing off an intent to start yourself and then dying quickly, but this sounds like a potential race condition depending on implementation. If you grabbed the binder fd out of /proc and did evil things in native code, you might be able to fire off the intent in such a way that your application crashes on the return from the ioctl...
