java.lang.RuntimeException: Cannot serialize: [] ----KSoap android

Question

I want to access wcf webservice as below code:

void farmCreate(String userName,
        String authToken) {
    String resultData = null;
    Hashtable<String, String> responseHashTable = new Hashtable<String, String>();
    try {
        FarmClass farm = new FarmClass();
        StringBuilder sb = null;
        SoapObject request = new SoapObject(Controller.NAMESPACE,  "MethodName");
        request.addProperty("aaaa", userName);
        request.addProperty("aaaa", authToken);
        request.addProperty("aaaa", farm);
        request.addProperty("aaaaa", "Add");

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);

          MarshalDate md = new MarshalDate();
            md.register(envelope);

            MarshalFloat md1 = new MarshalFloat();
            md1.register(envelope);

        HttpTransportSE androidHttpTransport = new HttpTransportSE(Controller.URL6767);
        androidHttpTransport.call(Controller.SOAP_ACTION + "method name", envelope);


        //new MarshalBase64().register(envelope);
        Object result = (Object) envelope.getResponse();

        resultData = result.toString();



    } catch (Exception e) {
        // TODO: handle exception
        e.printStackTrace();
        System.out.println("error is occured :-" + e.getMessage());
    }


}

But in response, generate one error as below :-

To serialize any object, you should implement Serializable. Try implementing Serializable class for FarmClass.
