Android -- Passing a string to an already created webservice

I'm trying to create an Android app that will pass a string to this (http://www.yodaspeak.co.uk/webservice/yodatalk.php?wsdl) webservice and then receive the string that it returns. I know I should be using the ksoap2 library, but I am unsure as to how to go about 开发者_开发问答even attempting to start going about this problem. I am very new to both Java and Android, so any code examples will not go unappreciated, but what I really need is some sort of explanation as to their use. Thank you so much in advance.

The ksoap2-android project site has a wiki including a page with bunch of links on it as well as a mailing list and more documentation.

I had written a (very) simple code example to demonstrate how to work with KSOAP2 in Android.
