Erreur "android.os.NetworkOnMainThreadException"
Bonjour,
Débutant en Java, je réalise une application Android qui relève de l'intranet de mon école.
Seulement voilà, je n'arrive pas à récupérer la réponse du serveur, mon getResponseCode() crash dans tous les sens, incapable de l'afficher/récupérer.

Quelqu'un saurait-il m'indiquer comment corriger ce problème ?
Merci d'avance pour votre aide.
