J'ai eu un problème avec l'analyse, quand je PHP basé sur le service Web. Je suis resté coincé à partir de 2 jours. Je ne peux pas obtenir de sortie dans Activity. Lorsque je l'ai imprimé dans Handler, j'ai réussi à imprimer la variable.
voici logcate:SAX parser soulever une erreur

Il semble que votre xml n'est pas bien formaté (pourrait avoir des caractères spéciaux). Je recommanderais loggest le XML et assurez-vous que vous obtenez le xml correct. – kosa
Pourriez-vous afficher le code XML que vous essayez d'analyser? –
Si votre xml est bien formé, je voudrais jeter un oeil ici: http://stackoverflow.com/questions/8827006/sax-expatparserparseexception. – javanna
