+0

il n'y a pas de description .. 10-18 17: 26: 54.584: ERROR/System (34): java.lang.SecurityException Il n'y a pas d'erreur quand j'exécute mon application mais quand mon application démarre sur émulateur je vois le message suivant : L'application s'est arrêtée de manière inattendue. Veuillez réessayer. – rockenpeace

La trace de la pile est pleine de ClassCastExceptions se projetés par le fil 49 de votre fichier BasicWebServiceActivity.java. La trace indique que la ligne incriminée est dans la méthode getListFromXML(). Je copiais votre code dans un éditeur de texte et pour moi la ligne 49 était:

NodeList nodeListText=((Document) elementMain).getElementsByTagName("text");

Ici vous caster des éléments comme des documents qui est l'origine du problème

Vous transtypez élément au document lorsqu'ils ne sont pas des cas de documents.

NodeList nodeListText=((Document) elementMain).getElementsByTagName("text"); 

NodeList nodeListValue=((Document) elementMain).getElementsByTagName("value");
