什么是webService呢？，它是一种基于SAOP协议的远程调用标准，webservice可以将不同操作系统平台，不同语言，不同技术整合到一起。我们在PC机器java客户端中，需要一些库，比如XFire,Axis2,CXF等等来支持访问WebService，但是这些库并不适合我们资源有限的android手机客户端，做过JAVA ME的人都知道有KSOAP这个第三方的类库，可以帮助我们获取服务器端webService调用，当然KSOAP已经提供了基于android版本的jar包了，那么我们就开始吧：

首先下载KSOAP包：ksoap2-android-assembly-3.0.0-jar-with-dependencies

注意：使用3.5.0的jar包时，间隔一段时间访问时，第一次总是出错，建议使用3.0
的可避免此情况

主要针对的是：含有请求头时，去除body标签里的id、root属性,子标签的i:type属性
