Ошибка при вызове .ASP.Net Веб-сервис с Android

Question

Я работаю над Android-приложением, которое необходимо сделать для вызова веб-службы в веб-службу ASP.Net. Я использую клиент KSOAP2, и это работает, но внезапно перестало работать.

Я изменил все последние изменения, которые я сделал без успеха.

Вот Android код

private final String NAMESPACE = "http://www.domain.com/"; 
     private final String URL = "https://www.domain.com/WebServices/LicenseActivationService.asmx"; 
     private final String SOAP_ACTION = "http://www.domain.com/"; 
     private String LOG_TAG = "ACTIVATION"; 
     private String methName = "ActivateLicense"; 
    String resultJSON = ""; 
       ActivationDTO activation = new ActivationDTO(); 
       activation.setLoginEmail(mEmail); 
       activation.setLoginPassword(mPassword); 
       activation.setDeviceId(getDeviceId(mcontext)); 


       //convert the activation object to a JSON String so it can be sent to the 
       //web service 
       Gson gson = new Gson(); 

       String jsonActivationRecord = gson.toJson(activation); 

       //make web service call 
       // Create request 
       SoapObject request = new SoapObject(NAMESPACE, methName); 
       // Property which holds input parameters 
       PropertyInfo paramPI = new PropertyInfo(); 
       // Set Name 
       paramPI.setName("serializedUserInfo"); 
       // Set Value 
       paramPI.setValue(jsonActivationRecord); 
       // Set dataType 
       paramPI.setType(String.class); 
       // Add the property to request object 
       request.addProperty(paramPI); 
       // Create envelope 
       SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
         SoapEnvelope.VER11); 
       envelope.dotNet = true; 
       // Set output SOAP object 
       envelope.setOutputSoapObject(request); 
       // Create HTTP call object 
       HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 

       try { 
        // Invoke web service 
        androidHttpTransport.call(SOAP_ACTION+methName, envelope); 
        // Get the response 
        SoapPrimitive response = (SoapPrimitive) envelope.getResponse(); 
        // Assign it to static result 
        resultJSON = response.toString(); 

       } catch (Exception e) { 
        e.printStackTrace(); 
       } 




       // TODO: register the new account here. 
       return resultJSON; 
      } 

А вот часть ASP.Net Web Service

[WebService(Namespace = "http://www.domain.com/")] 
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] 
[System.ComponentModel.ToolboxItem(false)] 
public class LicenseActivationService : System.Web.Services.WebService 
{ 


    [WebMethod] 
    public string ActivateLicense(string serializedUserInfo) 
    { 

     ActivationDto activationDTO = JsonConvert.DeserializeObject<ActivationDto>(serializedUserInfo); 
     String result; 


     if (activationDTO == null) 
     { 
      //return invalid input 
      activationDTO.IsActivated = false; 
      activationDTO.Result = "Input is empty"; 
      result = JsonConvert.SerializeObject(activationDTO); 
      return result; 
     } 

}

Что я мог отсутствовать или быть где я мог бы представил Жук. Последовательно сообщение об ошибке такое же

W/System.err: SoapFault - faultcode: 'soap:Server' faultstring: 'Server was unable to process request. ---> Object reference not set to an instance of an object.' faultactor: 'null' detail: org.kxml2.kdom.Node@432babe8

Answer 1

Это не должно составить, так как не все пути кода возвращают строку в вашем веб-службы.

Инициализировать переменную результата в веб-службе и вернуть результат вне вашего оператора if.

 [WebMethod] 
public string ActivateLicense(string serializedUserInfo) 
{ 

    ActivationDto activationDTO = JsonConvert.DeserializeObject<ActivationDto>(serializedUserInfo); 
    String result = ""; 


    if (activationDTO == null) 
    { 
     //return invalid input 
     activationDTO.IsActivated = false; 
     activationDTO.Result = "Input is empty"; 
     result = JsonConvert.SerializeObject(activationDTO); 

    } 
    return result; 

}
