Facebook login sorunu session kaydedilmiyor.

Arkadaşlar merhaba. Facebook ile bağlanma üzerine kod yazıyorum. meta-data, internet izni, com.facebook.LoginActivity falan herşey tamam durumda. Butona tıkladığım zaman istiyor da erişim iznini. İzin verince ana ekrana gelince kaydedilmiyor. DialogListener'de onComplete metoduna düşmüyor. Kodları paylaşacağım, yardımlarınız için şimdiden teşekkür ederim.
