insert and remove fragments into viewpager properly

Question

I\'m making an adroid application with viewpager and fragments. I want to make an option to add or remove fragment pages to the pager dynamically. I have a custom FragmentPagerA

Answer 1

I can remove any fragment except the 0.

For me it works if just use a >= condition whitin the removeItem's for-loop:

     if (i >= pos){
          fm.beginTransaction().remove(fragments.get(i).getFragment()).commit();
      }
