设备上的android应用程序连接到php脚本

Question

my english is not that good so i will try to explain my problem:

i have a group of .php files in a server (external webserver). i installed the android application on my tablet running android 3.2.1 and i need to:

1) call a php file that do the conection to the db (mysql database) 2) do some stuff on the db (always using the php files that do the work

i have download the tutorial from http://download.androidhive.info/download.php

i have tried in all the ways to make it work for my case but without any result.

maybe i'm just missing something...something really stupid (as always) that is making my connection fail. thansk in advance and i would love some advices (not just for the android java files but also for the php files)

<?php

/*
 * All database connection variables
 */

define('DB_USER', ""); // db user
define('DB_PASSWORD', ""); // db password (mention your db password here)
define('DB_DATABASE', "androidhive"); // database name
define('DB_SERVER', ""); // db server
?>

I think it's better to make the tests on localhost before, with WAMP or XAMPP.
And delete your database connection data before someone get into your database.
