Bonsoir,

Voilà j'ai une base de données qui contient cette table (image attachée).

J’ai ensuite créé ce script PHP qui permet d’interroger ma base de données.

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

<?php require_once "connect.php"; ?>
			<?php
				mysql_connect ($host,$user,$pass);
				mysql_select_db ($db);
				mysql_query("set names utf8");
				$sql = "SELECT * FROM people WHERE birthyear>'".$_REQUEST['year']."'";
				$result = mysql_query ($sql) or die(mysql_error());
					while( $row = mysql_fetch_assoc ($result) ) {
							print(json_encode($row));
					}
			mysql_close();
			?>

Ensuite via ce code JAVA:

je me connecte à ma page web via le protocole HTPP, puis je converti JSON pour les afficher dans le logcat sous le "tag".

Après teste, depuis mon androphone (samsung galaxy s), il arrive à se connecter à la page PHP puis la page renvoie cela :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

{"id":"1","name":"john","sex":"0","birthyear":"20"}{"id":"2","name":"toto","sex":"0","birthyear":"10"}{"id":"20","name":"john","sex":"0","birthyear":"20"}

Mais lors de l'affichage dans mon logcat il me met une erreur de parsing (image attachée).
