How to implement OnFragmentInteractionListener

Question

I have a wizard generated app with navigation drawer in android studio 0.8.2

I have created a fragment and added it with newInstance() and I get this error:

Answer 1

I'd like to add the destruction of the listener when the fragment is detached from the activity or destroyed.

@Override
public void onDetach() {
    super.onDetach();
    mListener = null;
}

and when using the new onStart() method with Context

@Override
public void onDestroy() {
    super.onDestroy();
    mListener = null;
}
