没有。

这已经无关编程preSS返回按钮。

  

我要寻找，对在后台运行的服务的解决方案。

您服务，欢迎发送邮件到的您的活动引起的活动来调用完成（）。可以使用以下任何这样的消息：

• LocalBroadcastManager


• 事件总线像奥托


• 一个常规的广播意图


• 在使者


• 等

不过，如果你的期望是，你将能够攻击活动的其他应用程序的的，强制的他们的调用完成（），这是不可能的。

Is it possible to programmatically press the back button on android through a service ?

I know I can override the onBackPressed() method if I were in an Activity, but I am looking for a solution that works for a service running in the background.

No.

I know I can override the onBackPressed() method if I were in an Activity,

That has nothing to do with "programmatically press the back button".

I am looking for a solution that works for a service running in the background.

Your service is welcome to send a message to your activity which causes the activity to call finish(). You could use any of the following for such a message:

• LocalBroadcastManager
• an event bus like Otto
• a regular broadcast Intent
• a Messenger
• etc.

However, if your expectation is that you will be able to attack the activities of other apps, forcing them to call finish(), that is not possible.
