API google maps

bonjour j'ai une petit soucis avec this dans ma fonction :

Code:

---

public void desabonnementGPS() { //Si le GPS est disponible, on s'y abonne locationManager.removeUpdates(this); }

---

voici l'erreur :

-------------------------------------------------------------------------------------------------------------------------
