  • IMO this question is too broad in scope for StackOverflow. You don't really have a concrete problem to debug, you have a fundamental misunderstanding/unfamiliarity with Android, Activities, and Fragments. That's fine; everyone starts from zero, but a different resource is probably a better bet for you. – Ben P. Nov 13 '18 at 17:52

That's not what FragmentActivity is used for. FragmentActivity is used to add the support library API for fragments and loaders to Activity. It does not turn a fragment into an activity.

If you have an existing fragment and want to use it as an activity, it's probably easiest to wrap the fragment in a very lightweight activity. The activity won't have much logic except for onCreate() where you'll set a layout that contains a fragment tag.
