Answer 2

Based on answer from @Ketan Mehta (https://stackoverflow.com/a/17397931/624109) that uses a deprecated API, you should use the following code:

@Override
public 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.newMeRequest(Session.getActiveSession(), new GraphUserCallback()
        {
            @Override
            public void onCompleted(GraphUser user, Response response)
            {
                if (null != user)
                {
                    // Display the parsed user info
                    Log.v(TAG, "Response : " + response);
                    Log.v(TAG, "UserID : " + user.getId());
                    Log.v(TAG, "User FirstName : " + user.getFirstName());

                }
            }
        }).executeAsync();
    }
}
