回答1:

my base URL is here: http://myapiname.azurewebservices.net

and feed method is like that :

public interface Iinterface{
   @GET("/feeds/json/v3/attribute/"+attribute)
   Call<ArrayList<result>>getresult();
}

And working perfectly. Please add http or https and try again

You do not have a protocol section. Prepend http:// or https:// depending on which applies to your url --

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("http://test-test.domainname.com")
        // ... other retrofit options
        .build();

In my case, my base url contained space character. (eg. http://myapiname.azure webservices.net )

I fixed this Error by removing space in my base URL.

Illegal URL Exception in retrofit is triggered when your passed url is not really existed or not fix with url standard.
