当我想用httpTransport调用webservice时，它会显示这个错误。（我的web服务是用microsoft c＃web应用程序创建的）

答案 0 :(得分：0)
我遇到了类似的问题，我想这个问题是因为我们用来连接网站的URL。所以我通过更改我的网站网址解决了这个问题，就像这个“http://www.example.com/index.php/api/v2_soap/?wsdl/”。
示例：
HttpTransportSE androidHttpTransport = new HttpTransportSE（http://www.example.com/index.php/api/v2_soap/?wsdl/，900000000）; androidHttpTransport.call（“”，env）;
