java.lang.IllegalStateException: Fragment no longer exists for key f1: index 3

Question

I want to understand this exception in order to implement a proper fix.

There\'s a ViewPager and it uses a FragmentStatePagerAdapter to instantiate 2 fragments via g

Answer 1

very good ! Since is repeat pager.setAdapter(adapter); when call restoreState cause exception:

Fragment no longer exists for key f0: index 0

we can Release Fragment RootView

    public void onDestroyView() {
    super.onDestroyView();
    if (isRecyclerRootViewAlways()) {
        mRootView = null;//<--
    }
    mMyFragmentLifecycle.onFragmentDestroyView(this);
}
