    Looks like you have a String input parameter that you didn't fill in, and the server doesn't interpret it as an empty string but just as a null, which is illegal for your SOAP service. Fix: set the string to something of length > 0. –  Oct 27 '11 at 06:36
  • Check out the parameter name in webmethod and android request.addProperty("parameter name", pXmlString) should match – Kalai.G Mar 05 '13 at 17:19

This error comes when you have not provided the correct URL, Method Name or Soap Action of the web service where you have hosted your web service. Other reason might be related to your hosting of webservice on tempuri, check it carefully will solve your problem

In my case the problem was the NameSpace, I was missing the "/" at the end of the namespace.
