如何在Android中检测应用程序的退出？

比标题说的更精确：

我正在使用SIP应用程序 sticky开始启动Sip堆栈时的服务，即使应用程序在后台运行很长时间，甚至当Android开始在资源变低时清除东西时仍保持活动状态。

minApi等级为15 。



我的技术问题是：

- 当用户从开放应用程序关闭应用程序时，我能以某种方式检测刷卡列表？或者这是一个简单而简单的杀死我的应用程序的过程，并且在被杀之前没有可用的钩子来执行最后的操作吗？



我需要实现什么是：

- 服务始终保持活动状态，无论应用程序是在前台还是后台，无论它在那里停留多长时间。

- 应用程序必须按主要活动（拨号器）上的后退按钮时不会退出 - 这是产品所有者的要求 - 该部分已解决。

但是...... - 这里开始我的问题：

- 当用户杀死应用程序时（即从应用程序列表中滑动），sip堆栈将执行关闭并且用户通过sip不可用 - 即离线 。技术为我的应用程序，这意味着：关闭Sip /停止粘性服务。



采取什么方法？



感谢任何tipps，这让我发疯。

Hi,

to be more precise, than the title says:
I am working on a SIP App which uses a "sticky" Service when starting to boot the Sip stack and to keep it alive even when the app is in background for a long time and even when Android starts purging things when resources get low.
minApi Level is 15.

My technical Problem is this:
- Can I somehow "detect" when the user closes the app from the open-apps-list with a swipe? Or is this a simple and plain "kill" of my app's process and there is no available hook to perform some last action before getting killed?

What I need to achieve is:
- Service stays active all the time, no matter whether the app is in foreground or background and no matter for how long it stays there.
- The App must not be "exited" when pressing the back button on the main activity (dialer) - this is by requirement of the product owners - that part is solved.
BUT... - and here starts my problem:
- When the user is "killing" the app (i.e. swipe from the app list), the sip stack shall perform a shutdown and the user is "not available" via sip - i.e. "offline". Technical for my app, this means: Shutdown Sip / Stop the sticky service.

What approach to take here?

Thanks for any tipps, this is driving me crazy.
cheers, Mike
