android facebook login Graphuser details

Question

i have a buttonLoginLogout Button which is a facebook login button (i imported the facebook sdk into my project) and this is my methods in my mainActivity:

its takes from LoginUsingActivityActivity sample from facebook activity, i didnt see a GraphUser or oncompleted mehod, so how can i get the user detailes that connected via facebook...

i tried to add "void onCompleted" method (in the end as you can see), however i cant override it and i cant get the user details, and when i login to facebook (and the login succeed) it doesnt get to the oncompleted method...

how can i get the GraphUser that logged into facebook successfully?

Also, i added the onCompleted method here, it wasn't here and it says that it is not override another moethod..

thanks alot

write this in a method:

final Session session = Session.getActiveSession();
    if (session != null && session.isOpened()) {
        // If the session is open, make an API call to get user data
        // and define a new callback to handle the response
        Request request = Request.newMeRequest(session, new Request.GraphUserCallback() {
            @Override
            public void onCompleted(GraphUser user, Response response) {
                // If the response is successful
                if (session == Session.getActiveSession()) {
                    if (user != null) {
                        user_ID = user.getId();//user id
                        profileName = user.getName();//user's profile name
                        userNameView.setText(user.getName());
                    }   
                }   
            }   
        }); 
        Request.executeBatchAsync(request);
    }

and make sure that this method is called only after a successfully login. that mean u should call it from the onActivityResult.
