I have a tabbed interface in my Mobile app (Android) and i am drawing a blank. i have fields in some of the tabs that need to be updated when an action happens from another tab. however i cannot for the life of me figure out how to refresh the controls. some have static fields that need to be populated, and some are loopers. the loopers populate on an app restart but i need it to be more or less in real time, while the user is using the app.
