Question

大家好，我有一個小問題，使用kso​​ap2。

我用ksoap與網絡服務進行通信，但它給了我下面的錯誤，請幫助朋友..因爲我是Android新手。代碼和例外記錄如下。它給了我例外的代碼try塊的第一行。 請看一看，並幫助

代碼是...

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

private static TextView tv; 

private final String SOAP_ACTION = "action";

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
