Answer 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

Answer 2

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();
