So guys I know that there exist a lot of similar question in here, but none of them have been able to resolve my issue.

I’m trying to send a custom Object User from an Android device to a WCF service, but no matter what I do the webservice receive a null.

Here's the code for the object im trying to send:

public class User implements KvmSerializable {

private int id; 
private String userName;
private String mac;
private int proppertyCount = 3;


public User(int _id, String _userName, String _mac)
{
    this.id =_id;
    this.userName = _userName;
    this.mac = _mac;
}

public User()
{

}


public int getId() {
    return id;
}
public void setId(int id) {
    this.id = id;
}
public String getUserName() {
    return userName;
}
public void setUserName(String userName) {
    this.userName = userName;
}
public String getMac() {
    return mac;
}
public void setMac(String mac) {
    this.mac = mac;
}

@Override
public Object getProperty(int arg0) {

    switch(arg0)
    {
        case 0: return id;

        case 1: return userName;

        case 2: return mac;

    }
    return null;
}

@Override
public int getPropertyCount() {

    return proppertyCount;
}

@Override
public void getPropertyInfo(int index, Hashtable arg1, PropertyInfo info) {

    switch(index)
    {
    case 0:
        info.type = PropertyInfo.INTEGER_CLASS;
        info.name = "CategoryId";
        break;
    case 1:
        info.type = PropertyInfo.STRING_CLASS;
        info.name = "Name";
        break;
    case 2:
        info.type = PropertyInfo.STRING_CLASS;
        info.name = "Description";
        break;
    default:break;
    }

}

@Override
public void setProperty(int index, Object value) {
    switch(index)
    {
    case 0:
        id = Integer.parseInt(value.toString());
        break;
    case 1:
        userName = value.toString();
        break;
    case 2:
        mac = value.toString();
        break;
    default:
        break;
    }

}

My method to pass the object through ksoap2:

        private static String SOAP_ACTION = "http://nordahl.org/IWcfFoodAndAllergi/";
    private static  String METHOD_NAME;
    private static final String NAMESPACE = "http://nordahl.org/";
    private static final String URL = "http://192.168.0.18/WcfFoodAndAllergi.svc";

    public void InsertUser(User _user)
    {

        METHOD_NAME = "InsertUser"; 
        SOAP_ACTION = SOAP_ACTION + METHOD_NAME;
        SoapObject result;
        int retInt = -1;

            SoapObject req = new SoapObject(NAMESPACE, METHOD_NAME);



            PropertyInfo p = new PropertyInfo();

            p.setName("User");
            p.setNamespace(NAMESPACE);
            p.setValue(_user);
            p.setType(_user.getClass());
            p.setType(_user.getClass());

            req.addProperty(p);

            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
            envelope.dotNet = true;
            envelope.implicitTypes = true;
            envelope.setAddAdornments(false);
            envelope.setOutputSoapObject(req);    

            envelope.addMapping(NAMESPACE, "User", new User().getClass());

            HttpTransportSE ht = new HttpTransportSE(URL); 

            try{
                    ht.debug= true;
                    ht.call(SOAP_ACTION, envelope);
                    result = (SoapObject)envelope.getResponse();
            }
            catch (Exception e)
            {
                e.printStackTrace();


            }
    }

And finally my wsdl file:
