i think json response wrong..

you need generate response this..

{"result":"sucess","data":[{"serv_name":"painting service"}, {"serv_name":"plumbing service"},{"serv_name":"electrical service"}, {"serv_name":"carpentry services"},{"serv_name":"aluminium works"}, {"serv_name":"house cleaning"},{"serv_name":"home appliance"}, {"serv_name":"glazing cleaning"},{"serv_name":"yard maintenance"}, {"serv_name":"water tank cleaning"},{"serv_name":"electronics services"}, {"serv_name":"upholstery services"},{"serv_name":"dry cleaners"}, {"serv_name":""}],"msg":" sucessfull"} 

then can parse response using below code..

string responce = json.getstring("data"); jsonobject servicejson = new jsonobject(responce); jsonarray jarray = servicejson.getjsonarray("data"); system.out.println("*****jarray*****" + jarray.length()); for(int i=0; i<jarray.length(); i++){    jsonobject json_data = jarray.getjsonobject(i);    string servicename = json_data.getstring("serv_name");    log.e("testing", "responce" + servicename); } log.e("testing", "responce" + responce);
