Menu
I have one Activity. The Activity has two Fragments. Fragment A is Menu. Fragment B is Detail.
I try to Make other Fragment C in Fragment B, so, There are 3 Fragment in the Activity. And I try to Replace Fragment B to Fragment D.
I guess Fragment B and C is dead. BUT these Fragments is alive. Just Fragments are onDestroyView() state. I want onDestroy() or onDetach().
What do I do for Fragments.onDestroy() or onDetach()? I can't destroy or change the Activity.

If you are using dynamic fragments, set up via a FragmentTransaction , you could run a transaction to replace() the old fragment with the new one.
To detach an added Fragment from an Activity, you use: getFragmentManager(). beginTransaction(). detach(mFragment). commit().
Use replace() to replace an existing fragment in a container with an instance of a new fragment class that you provide. Calling replace() is equivalent to calling remove() with a fragment in a container and adding a new fragment to that same container. transaction. commit();
If you don't remove manually these fragments, they are still attached to the activity. Your activity is not destroyed so these fragments are too. To remove (so destroy) these fragments, you can call:
fragmentTransaction.remove(yourfragment).commit() Hope it helps to you
