Admob in fragments

Question

I created an empty project with appcompact and tried to add to it the AdMob block

fragment_main.xml

Answer 1

You have

View rootView = inflater.inflate(R.layout.fragment_main, container,
                false);
return rootView; // remove this
adView = new AdView(getActivity()); // this is unreachable coz you have return above.

The return at the end of onCreateView is fine
