final String SOAP_ACTION = "http://tempuri.org/MyFunction";
    final String METHOD_NAME = "MyFunction";
    final String NAMESPACE = "http://tempuri.org/";
    final String URL = "http://localhost:23250/WS1.asmx";
    final SoapObject requestObject = new SoapObject(NAMESPACE, METHOD_NAME);
    requestObject.addProperty("UserIdentifier", "");
    requestObject.addProperty("PhoneIdentifier", "");

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    envelope.dotNet = true;
    envelope.setOutputSoapObject(requestObject);

    try
    {
        HttpTransport androidHttpTransport = new HttpTransport(URL);
        androidHttpTransport.call(SOAP_ACTION, envelope);
        SoapObject response = (SoapObject)envelope.getResponse();
        String result =  response.getProperty(0).toString();
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }

Answer 1

您需要下载j2se版本而不是j2me版本。

Answer 2

在我尝试调试我的应用程序时出现了同样的错误。我能够通过重新链接KSOAP2 SE库而不是使用me版本来纠正它。

Answer 3

我遇到了同样的错误，我必须清除Java Build Path中的所有条目，除了Android＃。＃（其中＃。＃是你在项目中使用的版本号）。然后我清理了项目（项目，清洁），一切似乎都有效。

Answer 4

原来这是一个程序员错误

我正在调用一种不存在的网络方法。

没有名为MyFunction的方法
