    <p>I am trying to use ksoap2 to access methods in a wcf soap service from android. I was able to successfully pass simple type parameters to the method, it worked fine. But when I try to pass objects, the wcf method is receiving 0 for all the object values.</p> <p>I have used the same SOAP service with a WP7 app and it runs fine.</p> <p>I have 2 methods in my service, ksoapadd and addParam. addParam takes in two integer and returns their sum(this works). ksoapadd takes in an object of class testadd which has two integer elements and ksoapadd returns their sum(this gets and sends 0).</p> <p>I think it has something to do with the namespace but I can't figure out how to resolve it. I have been doing trial and error to get the soap request right, but no luck yet.</p> <p>Can anyone help me figure out what to do? I have tried many options which somehow helped other people with similar problem but with no avail. </p> <p>here is my wsdl:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; -&lt;wsdl:definitions xmlns:wsx="http://schemas.xmlsoap.org/ws/2004/09/mex" xmlns:wsa10="http://www.w3.org/2005/08/addressing" xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:wsaw="http://www.w3.org/2006/05/addressing/wsdl" xmlns:msc="http://schemas.microsoft.com/ws/2005/12/wsdl/contract" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsap="http://schemas.xmlsoap.org/ws/2004/08/addressing/policy" xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy" xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/addressing" xmlns:tns="http://tempuri.org/" xmlns:wsam="http://www.w3.org/2007/05/addressing/metadata" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" targetNamespace="http://tempuri.org/" name="Service1"&gt;

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
