Nobody?
I have another maybe stupid questions. Im new to FB SDK, so excuse me please.
Is possible to get, number of friends player selected in the FB.Mobile.AppInvite dialog? In callback function i found just “callback_id” : “int” and “didComplete” : “bool”.

Or, can someone help me with this AppRequest callback from old fb sdk 6.x get working on new sdk 7.4.0. I found this code here:Unity3d Tutorials - How to - Learn Unity: How to invite friends using Facebook SDK for Unity3D
Sorry for my english, thank you.

private void RequestCallback(FBResult result)
    {
        if (result != null)
        {
            var responseObject = Json.Deserialize(result.Text) as Dictionary<string, object>;
            IEnumerable<object> objectArray = (IEnumerable<object>)responseObject["to"];

            if (objectArray.Count() >= 3)
            {
                // do something
            }
        }
    }
