大家好我使用ksoap2时遇到了一些问题。

我使用ksoap与Web服务进行通信，但它给了我以下错误，请帮助朋友..因为我是Android新手。代码和异常日志cat如下所示。它在我的代码中try块的第一行给出了异常。请看看并帮助

代码是......

/***********************************************

 private  final String SOAP_ACTION = "action";
 private  final String METHOD_NAME = "login";
 private  final String NAMESPACE = "namspace";
 private  final String URL =  "url";

 private Object resultRequestSOAP = null;

Answer 1

SoapObject userRequest=new SoapObject(NAMESPACE, METHOD_NAME);
     String email = userName.getText().toString();
     String pass = password.getText().toString();


     userRequest.addProperty("email", email); // login-account
     userRequest.addProperty("password", pass); // login-password
     request.addProperty("UserLogin", userRequest); // login-account
