I have spent the better part of two days searching for an answer that solves my question, I have found plenty that come close but not specific to what I need:
I would like to add a new FragmentActivity to a viewPager from inside a current FragmentActivity by calling the FragmentPageAdapter (or at least, this is how I see I need to solve my problem).
For example: In fragment 1 I would like to press a button to update and replace Fragment 2 with new data, and then set Fragment 2 as the currently viewed fragment.
