How to get all running activities android?

I was wondering is there a way of g开发者_StackOverflowetting a list with all running activities ?

As far as I understand there will only one activity running at a time that will be your active activity on screen, other activities will be in paused or Stopped state if any.

No, as far as I know there is no built in way to get a list of running activities (assuming running - means non-destroyed activities).

If you only need a list of activities in your application, you can create some kind of "registrar" mechanism, so each activity registers in onCreate() and unregisters in onDestroy(). This should be some singleton class, because it should automatically be "cleared" if application is killed (as opposed to storing list of active activities in DB).
