onAttach(Activity) deprecated: where I can check if the activity implements callback interface

Question

Before API 23 I used Fragment\'s onAttach methods to get my listener instance, then the reference is cleaned inside onDetach. ex:

@Override
public void onAtt         


        

Answer 1

Well, what is deprecated is onAttach(Activity activity); method, but the whole flow remains. so you may do nothing really as onAttach(Activity activity); is going to be still supported long enough.
