Location Fragment mit Map - Camera zoomt nicht in die Map? C#

Hei Leute
Ich habe ein Fragment dass mit einer Map verknüpft ist.
In dieser Map soll die App automatisch zur Position hineinzoomen.
Doch irgendwie gelingt es mir nicht dass die kamera selbstständig zur position hineinzoomt.
Der Code ist ähnlich aufgebaut wie in Java also die die nur Java können können hier auch helfen!

Hier mal der code:
Fällt jemanden was auf?

loccat wird auch nichts angezeigt.....
Entweder ich bekomme gar keine GPS Positionen rein
Oder etwas mit dem Camera Code ist falsch

Hier ist mein überarbeitetert Code aber immernoch das selbe:

        }


        public void OnProviderDisabled(String provider)
        {
            //Not implemented
        }

        public void OnProviderEnabled(String provider)
        {
            //Not implemented
        }

        public void OnStatusChanged(String provider, Availability status, Bundle extras)
        {
            //Not implemented
        }


        //Wenn man auf einen Marker klickt
        private void MapOnMarkerClick(object sender, GoogleMap.MarkerClickEventArgs markerClickEventArgs)
        {

            //Not implemented
        }


    }
}

Also ich bin der Meinung dass einfach keine GPS Positionen reinkommen
