httpclient - android HttpGet/HttpPost parameters allways arrive as null to the server -


i'm trying send data server seems send null values, idea? idea add new customer through mobile application database hosted in server.

here's code:

    protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_nuevo_insert);      //etresponse = (edittext) findviewbyid(r.id.etresponse2);     etnombre = (edittext) findviewbyid(r.id.etnombre);     etapellido = (edittext) findviewbyid(r.id.etapellido);     etedad = (edittext) findviewbyid(r.id.etedad);      nombre = etnombre.gettext().tostring();     apellido = etapellido.gettext().tostring();     edad = etedad.gettext().tostring();      }       public void insertar(view view) {     // call asynctask perform network operation on separate thread     // working in localhost can't put localhost in address,     // must put ip address or crush     new httpasynctask().execute("http://192.168.1.34/android/insertcustomer.php");     }      public static string get(string url) {     inputstream inputstream = null;     string result = "";     try {         // create httpclient         httpclient httpclient = new defaulthttpclient();          // make request given url         httpresponse httpresponse = httpclient.execute(new httpget(url+ "?nombre=" +    nombre + "&apellido=" + apellido + "&edad="+ edad));          // receive response inputstream         inputstream = httpresponse.getentity().getcontent();          // convert inputstream string         if (inputstream != null) {         result = convertinputstreamtostring(inputstream);         } else {         result = "no ha funcionat!";         }      } catch (exception e) {         log.d("inputstream", e.getlocalizedmessage());      }         return result;     }      private class httpasynctask extends asynctask<string, void, string> {      @override     protected string doinbackground(string... urls) {         return get(urls[0]);     }      // onpostexecute displays results of asynctask     @override     protected void onpostexecute(string result) {         string s = "";         toast.maketext(getbasecontext(),getresources().getstring(r.string.rebut), toast.length_long).show();     jsonarray jarray;     try {         jarray = new jsonarray(result);         (int = 0; < jarray.length(); i++) {         jsonobject json = jarray.getjsonobject(i);          s = s + "nom: " + json.getstring("firsname") + " "             + json.getstring("lastname") + "\n" + "edat: "+ json.getint("age") + "\n\n";         }         etresponse.settext(s);     } catch (jsonexception e) {         // todo auto-generated catch block         e.printstacktrace();     }  } }

this php file:

    <?php         $con = mysql_connect('localhost', 'root', '');          if(!$con){          die("no se ha podido realizar la conexion: ".mysql_error());          }          mysql_select_db("testdatabase", $con);          $nombre = $_get['nombre'];         $apellido = $_get['apellido'];         $edad = $_get['edad'];          print_r($nombre."-".$apellido."-".$edad);          $result = mysql_query("insert customer(firsname, lastname, age) values         ('$nombre', '$apellido', '$edad')");          mysql_close($con);  ?>

if getting null value means mean u r passing wrong type parameters or url may wrong check out
