关于Android的KSoap2的使用

直接对SoapObject传入NameSpace 和 MethodName之后，生成的报文类似于：

...

...(省略其他)

<n0:MethodName xmlns:n0="....">

....(参数省略)

.....

</n0:MethodName>

有些webservice对这种报文能够正确的识别和解释。但是有的不能（能够访问到相应的方法，但是不能设置相应的参数的值）。

经过对KSoap2的源代码的分析，最后找到了适合项目需求的解决方案：

修改源代码文件的org/ksoap2/serialization/SoapSerializationEnvelop.java中的writeBody（）方法，如下：

public void writeBody(XmlSerializer writer) throws IOException
	{
		// allow an empty body without any tags in it
		// see http://code.google.com/p/ksoap2-android/issues/detail?id=77
		if (bodyOut != null) {
            multiRef = new Vector();
            multiRef.addElement(bodyOut);
            Object[] qName = getInfo(null, bodyOut);
