You need to ask for parameters to facebook in order to get your data. Here I post my function where I get the facebook data. The key is in this line:

parameters.putString("fields", "id, first_name, last_name, email,gender, birthday, location"); // Parámetros que pedimos a facebook

Hope it helps you.

btnLoginFb.registerCallback(callbackManager, new FacebookCallback() {

        @Override
        public void onSuccess(LoginResult loginResult) {

            System.out.println("onSuccess");
            progressDialog = new ProgressDialog(LoginActivity.this);
            progressDialog.setMessage("Procesando datos...");
            progressDialog.show();
            String accessToken = loginResult.getAccessToken().getToken();
            Log.i("accessToken", accessToken);

            GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {

                @Override
                public void onCompleted(JSONObject object, GraphResponse response) {
                    Log.i("LoginActivity", response.toString());
                    // Get facebook data from login
                    Bundle bFacebookData = getFacebookData(object); 
                }
            });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id, first_name, last_name, email,gender, birthday, location"); // Parámetros que pedimos a facebook
            request.setParameters(parameters);
            request.executeAsync();
        }

        @Override
        public void onCancel() {
            System.out.println("onCancel");
        }

        @Override
        public void onError(FacebookException exception) {
            System.out.println("onError");
            Log.v("LoginActivity", exception.getCause().toString());
        }
    });

                Log.i("profile_pic", profile_pic + "");
                bundle.putString("profile_pic", profile_pic.toString());
