Answer 1

This might be late but Retrofit allows you to use dynamic URLs while making the network call itself using @Url annotation. I am also using Dagger2 to inject the Retrofit instance in my repositories and this solution is working fine for me.

This will use the base url

provided by you while creating the instance of Retrofit.

@GET("/product/123")
fun fetchDataFromNetwork(): Call<Product>

This ignore the base url

and use the url you will be providing this call at run time.

@GET()
fun fetchDataFromNetwork(@Url url : String): Call<Product> //

Answer 2

Retrofit2 library comes with a @Url annotation. You can override baseUrl like this:

API interface:

public interface UserService {  
    @GET
    public Call<ResponseBody> profilePicture(@Url String url);
}

And call the API like this:

Retrofit retrofit = Retrofit.Builder()  
    .baseUrl("https://your.api.url/");
    .build();

UserService service = retrofit.create(UserService.class);  
service.profilePicture("https://s3.amazon.com/profile-picture/path");
