Bonjour,

J'aimerais implémenter un AlertDialog dans un Service, de manière à lui faire afficher un message d'urgence.

Lorsque j'essaie d'afficher l'AlertDialog avec ma classe Service, j'ai l'erreur suivante dans le LogCat :

Quelqu'un saurait-il m'indiquer d'où peut venir le problème ?

Merci d'avance pour votre aide.
