I have an android app that has two fragments that pass data from fragmentA to fragmentB. I can load all the data correctly but when I change the screen orientation it all reloads. I have set up the onSaveInstanceState and onViewStateRestored methods in the fragment I want to keep the state in, but nothing stays when the screen orientation changes.

The main problem that needs to be fixed is when text is loaded into the TextView in FragmentB - it needs to stay there when the screen orientation is changed.
