Cześć,
Probuje ściągnąc za pomocą retrofita i wyświetlic używającGlide randomowy obraz z lorem.picsumw recyclerView. Ustawiam base URL, dodaje annotacje jako rozmiar obrazu (200). Nie wiem gdzie jest błąd. Dla statycznej tablicy ze stringami w postaci linkow dziala, takze zakladam, ze adapter jest dobrze napisany. Bede wdzięczny za każdy hint.

public interface ApiService {
@GET("200/")
Call<List<Pictures>> getFile();
