Bonjour tout le monde

je veux récuperer les donnes de mysql et l'afficher dans un listView

j’essaye de récupérer le données avec un code que je trouve dans un tutorial sur internet mais j'ai rien recu rien dans l'emelateur

et d’après le logcat : j’espère que j'ai deux problèmes 1- HttpResponse reponse = client.execute(requete);
2- JSONArray jArray = new JSONArray(stringB.toString());
lorsque je fait le test de code php sur le navigateur sous http://192.168.56.1/testAff/testAff.php il affiche correctement

Est ce que quelqu'un peut m'aider svp

Et merci d'avance
