推荐答案

有没有广播时应用启动就知道了。你可以有定期检查当前正在运行的任务列表中的服务运行，看是否有特定的应用程序已经启动。

There is no broadcast to know when an app is launched. You can have a service running which has to periodically check the currently running tasks list to see if a particular app has been launched.

您绝对可以让没有通知图标的服务运行，但只会增加你的服务被杀的可能性。

You definitely can make the service run with no notification icon, but that will simply increase the probability of your service getting killed.

您可以了解从这里的服务： http://developer.android。 COM /参考/安卓/应用/ Service.html

You can learn about services from here : http://developer.android.com/reference/android/app/Service.html

您可以获取正在运行的任务从getRunningTasks名单（）的ActivityManager的方法。

You can get the list of running tasks from getRunningTasks() method of the ActivityManager.
