As far as I remember, to interact with API Vkontakte or Facebook requires that the user has allowed Your "app" to obtain any information of the user. This is done through a pseudo authorization through API (http://developers.facebook.com/docs/authentication/).
Up to this point in the API is void or defaultnya record.
The user has the app installed and has logged in. - Jace95 commented on October 8th 19 at 03:38
