Answer 1

The key hash you're passing to the Facebook SDK isn't stored with your developer account.

W/fb4a(:):BlueServiceQueue(10494): com.facebook.http.protocol.ApiException: Key hash rhDpGcyTNP33kRZOYIKdOcoevoM does not match any stored key hashes. 

Go to developers.facebook.com/apps/ and add it in the android section (key hash rhDpGcyTNP33kRZOYIKdOcoevoM)
