java - KSoap2 + Android + .net Ws = Null -

i'm having issues using ksoap2 in android project while conecting .net webservice. long call ws witouth parameters works fine, when try add parameters, servers never gets them. here's code

import java.util.vector;  import org.ksoap2.soapenvelope; import org.ksoap2.serialization.propertyinfo; import org.ksoap2.serialization.soapobject; import org.ksoap2.serialization.soapprimitive; import org.ksoap2.serialization.soapserializationenvelope; import org.ksoap2.transport.androidhttptransport;  import android.app.activity; import android.os.bundle; import android.widget.arrayadapter; import android.widget.listview; import android.widget.textview; import android.widget.toast;  public class servicioweb extends activity {  soapobject response;  public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.main);    // string namespace = "http://tempuri.org/";     string namespace = "idbn.ws";     string method_name = "getclientesbyname";     //string soap_action = "http://tempuri.org/getclientesbyname";     string soap_action = "idbn.ws/getclientesbyname";     //string url = "http://www.ws.idbnar2.com.ar/wsclientes.asmx";     string url = "http://www.ws.idbnar2.com.ar/wsclientes.asmx";     soapobject request = new soapobject(namespace, method_name);    propertyinfo pi = new propertyinfo();     pi.setname("nombre");     pi.setvalue("riquelme");     pi.settype(int.class);     request.addproperty(pi);      soapserializationenvelope envelope = new soapserializationenvelope(soapenvelope.ver11);     envelope.dotnet = true;     envelope.setoutputsoapobject(request);     androidhttptransport androidhttptransport = new androidhttptransport(url);     listview lista = (listview)findviewbyid(r.id.lista);      try     {         androidhttptransport.call(soap_action, envelope);         response = (soapobject)envelope.getresponse();         string[] clientes = getstringarrayresponse(response, null);         lista.setadapter(new arrayadapter<string>(this, android.r.layout.simple_list_item_1,clientes));     }     catch(exception e)     {         toast toast = toast.maketext(this, e.getmessage(), toast.length_long);         toast.show();     } }  public string[] getstringarrayresponse(soapobject node, vector<string> strings) {     boolean isfirstcall = false;     if (strings == null) {         isfirstcall = true;         strings = new vector<string>();     }     int count = response.getpropertycount();     (int = 0; < count; i++) {         object obj1 = node.getproperty(i);         if (obj1 instanceof soapobject) {             // don't recurse empty objects             if (((soapobject)obj1).getpropertycount() > 0) {                 // recurse node process nodes/primitives                 getstringarrayresponse((soapobject)obj1, strings);             }         } else if (obj1 instanceof soapprimitive) {             strings.add(((soapprimitive)obj1).tostring());         }     }     // make original caller     if (isfirstcall) {         return (string[])strings.toarray(new string[strings.size()]);     }     return null; } } 

i harcode server side, return string + parameters send it.. , it's hardcoded part, seems parameters add soap objets never receives server.

allready try : -) removing "http://" namespace on webservice -) not using "envelope.dotnet = true;" -) adding property directly request

any idea wha'ts wrong???

these lines confuse me:

propertyinfo pi = new propertyinfo(); pi.setname("nombre"); pi.setvalue("riquelme"); pi.settype(int.class); request.addproperty(pi); 

why use string ("riquelme") value integer?

what happens when run code? try setting envelope.debug = true. trying setting breakpoint , inspecting value of envelope.requestdump , envelope.responsedump. way can see sent , received.
