You should be used new facebook sdk 3.0 and

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
        if (Session.getActiveSession().isOpened()) {
            // Request user data and show the results
            Request.executeMeRequestAsync(Session.getActiveSession(), new Request.GraphUserCallback() {

                @Override
                public void onCompleted(GraphUser user, Response response) {
                    // TODO Auto-generated method stub
                    if (user != null) {
                        // Display the parsed user info
                        Log.v(TAG, "Response : " + response);
                        Log.v(TAG, "UserID : " + user.getId());
                        Log.v(TAG, "User FirstName : " + user.getFirstName());

                    }
                }

            });
        }
    }
