Des suggéstions ?

Bonjour,

Et si tu utilisais KSoap (si possible), ce ne serait pas plus simple ?
Un tuto sur l'utilisation de KSoap : Appel d’un Webservice depuis Android avec KSoap

Sinon ne peux-tu pas nous montrer un message d'erreur, quelque chose qui nous donne une piste de réflexion ?

Merci Viish,

J'ai aucune erreur c'est juste que je ne reçoit pas le résultat.
Si tu pouvais vérifier si j'ai mis la bonne url.

En effet, l'émulateur Android ne reconnait pas localhost comme la machine hébergeant l'émulateur. Essayes plutôt avec 10.0.2.2 à la place.

Tu as bien remplacé

Code:

private static final String URL = "http://localhost:8080/MonServiceWEB/services/AddNumber";

par

Code:

private static final String URL = "http://10.0.2.2:8080/MonServiceWEB/services/AddNumber";
