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:

In addition to @user26409021 's answer, If you have added a ItemFragment, The message in the ItemFragment is;

Activities containing this fragment MUST implement the {@link OnListFragmentInteractionListener} interface.

And You should add in your activity;

public class MainActivity extends AppCompatActivity
    implements NavigationView.OnNavigationItemSelectedListener, ItemFragment.OnListFragmentInteractionListener {

//the code is omitted

 public void onListFragmentInteraction(DummyContent.DummyItem uri){
    //you can leave it empty
}

Here the dummy item is what you have on the bottom of your ItemFragment
