通过观察变量 urlc.getResponseCode() 的响应代码，同时从 localhost 更改 ip，使用以下代码确保 web 服务的 url 可访问 后，固定，外部，最后到 10.0.2.2
public static boolean isNetworkAvailable() {

对我来说，我得到了这个提示“不是下面缺少的字符 s”

是的，在跟踪 LogCat 之后，如果服务被 SoapUi 测试成功，我没有检查 th tomcat 服务器日志，你应该在每次更改测试中监控所有日志，我什至一开始忘记启动数据库服务所以小心:)
肥皂电话
public SoapObject SoapCall(Vector<PropertyInfo> propertyInfo)
{
Integer parametersSize = propertyInfo.size();
//Initialize soap request + add parameters
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
for(int i=0;i<parametersSize;i++)
{
request.addProperty(propertyInfo.get(i));
}
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
//envelope.dotNet = false; if service of type asmx .NET
envelope.setOutputSoapObject(request);
Log.d("App Log c ","c");
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try {
System.out.println(androidHttpTransport.getPort());
// Make the soap call.
//this is the actual part that will call the webservice
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
//Log.i("App Log 1 ", response.toString());
} catch (Exception e) {
e.printStackTrace();
}
// Get the SoapResult from the envelope body.
SoapObject result = (SoapObject)envelope.bodyIn;
Log.i("App Log 2 ", result.toString());
Log.i("App Log 2 ", result.getProperty(0).toString());
return result;
}
Vector<PropertyInfo> vectorProperyInfo = new Vector<PropertyInfo>();
PropertyInfo userProp = new PropertyInfo();
userProp.setName("userName");
userProp.setValue(username);
userProp.setType(String.class);
vectorProperyInfo.addElement(userProp);
PropertyInfo passProp = new PropertyInfo();
passProp.setName("pass");
passProp.setValue(password);
passProp.setType(String.class);
vectorProperyInfo.addElement(passProp);
SoapObject result = soapUtil.SoapCall(vectorProperyInfo);
if (result != null && result.getProperty(0).toString().equals("1")) {
return "LOGIN_SUCCESS";// for a student
}
P.S我的数据库是Oracle，webservice是soap并使用axis2-1.2 bin并在Android 4.0上测试上述错误响应代码为500 Internal Error
