Answer 1

This is know issue look here

This is a bug in the nested fragments. Basically, the child FragmentManager ends up with a broken internal state when it is detached from the activity.

A short-term workaround is to add the following code in your fragment.

@Override
public void onDetach() {
super.onDetach();

try {
     Field childFragmentManager = Fragment.class.getDeclaredField("mChildFragmentManager");
     childFragmentManager.setAccessible(true);
     childFragmentManager.set(this, null);
     } catch (NoSuchFieldException e) {
        throw new RuntimeException(e);
     } catch (IllegalAccessException e) {
        throw new RuntimeException(e);
    }
}
