ksoap2 101 如何

Question

下面的代码似乎使我的应用程序崩溃

不知道为什么

帮助赞赏。

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();
    }

我可以从浏览器调用 Web 服务，

下面是 LogCat 数据

Answer 1

您需要下载j2se版本而不是j2me版本。

Answer 2

当我尝试调试我的应用程序时也出现了同样的错误。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 构建路径中除 Android #.# 之外的所有条目（其中 #.# 是您在项目中使用的版本号）。然后我清理了项目（Project，Clean），一切似乎都正常。

Answer 4

事实证明这是一个程序员错误，

我调用了一个不存在的 webmethod。

没有名为 MyFunction 的方法
