After a long time thinking about my problem, I had the following idea: maybe the problem is related to the fact that I'm removing the fragment that has the ViewPager, but I'm not removing the fragments used by the ViewPager. Then, these fragments continues in the FragmentManager and something strange happens when the new ViewPager tries to use them.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
