causing a java.IllegalStateException error, No Activity, only when navigating to Fragment for the SECOND time

Question

I am getting a very puzzling bug that I have no idea how to even begin working through.

I have a simple app with one activity, the views are implemented with Fragme

Answer 1

Please check number 32 of this link :

Child FragmentManager retained after detaching parent Fragment

Steps:

1. Download and copy this class to your project
2. extend every Fragment with the support v4 one(best practice)
3. use that class instead of FragmentStatePagerAdapter
