Listen to ActivityManager events?

Question

is it possible somehow to listen to the events of the ActivityManager, e.g. when activities are started? Does the ActivityManager send broadcasts? I havn\'t found anything i

Answer 1

I suppose there is no actually other legacy way to handle glabal system state, only

 (ActivityManager)getSystemService(Context.ACTIVITY_SERVICE);

ActivityManager.getRecentTasks() - Return a list of the tasks that are currently running, with the most recent being first and older ones after in order.

For details check docs

Perhaps though Android is a Linux you can run system tools like

Runtime.getRuntime().exec("ps -aux | grep smth")

But I think it would be hard to detect particular java application.
