AlertDialog dans API Google Maps
Bonjour à tous.
Je suis actuellement en train de réaliser une application de géo-localisation.
J'ai pour cela suivi le tutoriel android suivant : http://developer.android.com/resourc...o-mapview.html
Je n'ai aucun soucis pour ajouter mes marqueurs sur la carte qui permettent de savoir ou je suis passé mais le soucis arrive lorsque je souhaite clicker sur un marqueurs android qui doit m'afficher une boite de dialogue.
L'erreur se produit à l'appel de la méthode onTap().
J'obtiens l'erreur suivante :

Cela fait maintenant un bon moment que je cherches sur les différents forum mais je ne trouve toujours pas la solution.
Je m'adresse donc à vous.
Je vous remercie d'avance pour votre aide précieuse. :)
