如何在Android应用程序中将数据插入服务器

I am developing an android application where the user data should be pushed onto the server .How can i do that ? I was able to get data from the server but unable to insert it. Code snippet would be good.I have tried this but it doesn't work.

Java Code :

String data="xyz.org/json.php"+"?"+"&"+URLEncoder.encode("data", "UTF-8") + "="+"order";
URL url;
url = new URL(data);
URLConnection conn = url.openConnection(); 
conn.setDoOutput(true);

In json.php :

$data = urldecode($_GET['data']);
if($data=="order")
{
   $query="insert into xyz values('$x','$y','$z')";
   $query_run=mysql_query($query);
}

you need a httppost or httpget dependance on the your url method for that you can use Httppost and get follow this url you get some idea and also check this url for asynctask beacuse you have to put all the network related you have to put in the asynctask.
