Can't Read Rss Xml , With Simple Xml And Retrofit

I have searched a lot, but I can't assign my XML with My Classes and I take an Error from Retrofit when I am trying to Deserialize the XML. This is the XML that I call from my Int

Solution 1:

Eventually I changed my Callback and it Worked . I had to use the Model Class Rss in the Callback for example :

publicinterfaceApiService {
     @GET("/?feed=single_gallery_feed")
     void getGadgets(@Query("paged")int page, Callback<Rss> gadgetsCallback);
}

And the Callback inside MainActivity:

RestClientrestClient=newRestClient();
        Callbackcallback=newCallback() {
            @Overridepublicvoidsuccess(Object o, Response response) {
                Categories_ = (Categories)o;
            }

            @Overridepublicvoidfailure(RetrofitError error) {
                Toasttoast= Toast.makeText(getApplication(), "Something went wrong!!", Toast.LENGTH_SHORT);
                toast.show();
            }
        };
        restClient.getApiService().getCategories(callback);
