Display multiple actions on one screen

Question

Is it possible to simultaneously show two actions on the same screen? I need each action to display data that changes over time.

Answer 1

Or maybe you can use AndroidFragments

Answer 2

It's late after the question. But you should look at an ActivityGroup

Inherits from Activity, so you should be able to run this as a parent.

Answer 3

Yes, it is definitely possible. Even when you display a menu or dialogue, this menu / dialogue is a separate action that runs on top of yours. However, you should avoid this as much as possible. It is useful to simultaneously display two actions if one of the actions does not apply to your application (which is the case in menus / dialogs). If both actions come from your own application, you must find a way to combine them into one. Thus, you use less memory and less CPU (since there is no overhead to start a new process).
