如何在android中为数据库调用soap的web服务。
我的Web服务在C＃中的ASP.NET中。
为什么NewDataSet和Table值没有显示在android中的soap web服务中 请回答。

我的网络服务结果是：

好的..首先，当您为网络侧或服务器端进行编码时使用 AsynTask
的好习惯所以我告诉你如何正确地执行你的代码。
public class ExampleClass extends Activity {
SoapObject result;
SoapSerializationEnvelope envelope_test = new SoapSerializationEnvelope(
SoapEnvelope.VER11);

确定您的所有NameSpace，方法名称.URL是正确的
