mapView показывает только логотип Google

Question

Я пытаюсь показать вид карты в своей активности, и он не показывает ничего, только логотип Google

Я попытался изменить ключ API и создать другие ключи, но он не работает, и я уверен, что я включилслужбы API, я скопировал код из примеров Google для карт, так что я думаю, что мой класс Java хорошо подходит, я думаю, что это что-то в ключах API Google, но я создал его несколько раз и создал новый проект, и не работает
