Issue in android programming json to listview -

i have been using following code in order create listview:

public class androidjsonparsingactivity extends listactivity {   // url make request private static string url = "http://api.androidhive.info/contacts/";  // json node names private static final string tag_contacts = "contacts"; private static final string tag_id = "id"; private static final string tag_name = "name"; private static final string tag_email = "email"; private static final string tag_address = "address"; private static final string tag_gender = "gender"; private static final string tag_phone = "phone"; private static final string tag_phone_mobile = "mobile"; private static final string tag_phone_home = "home"; private static final string tag_phone_office = "office"; 

this 1 above works, if change into:

private static string url = "http://kondicioner.al/app/json.php";      // json node names     private static final string tag_contacts = "contacts";     private static final string tag_id = "id";     private static final string tag_name = "emer";     private static final string tag_email = "mbiemer";     private static final string tag_address = "telefon";     private static final string tag_gender = "adresa";     private static final string tag_phone = "ora";     private static final string tag_phone_mobile = "per";     private static final string tag_phone_home = "dyqan";     private static final string tag_phone_office = "statusi"; 

it won't work now.i don't understand may problem, it's supposed work, same structure same thing... thanks

the json structures different.

this how first structure looks (i have retained 1 record brevity):

{    "contacts":[       {          "id":"c200",          "name":"ravi tamada",          "email":"ravi@gmail.com",          "address":"xx-xx-xxxx,x - street, x - country",          "gender":"male",          "phone":{             "mobile":"+91 0000000000",             "home":"00 000000",             "office":"00 000000"          }       }    ] } 

and how second structure looks like:

{    "contacts":[       {          "id":"12",          "emer":"albana",          "mbiemer":"",          "telefon":"",          "adresa":"",          "ora":"10:13:44",          "per":"",          "dyqan":"",          "statusi":"",          "orari_transportit":"",          "data":"15\/4\/2013"       }    ] }
