Как настроить FirebaseAdapter в Android Studio?

Я пытаюсь читать данные в реальном времени из Firebase в пользовательский ArrayAdapter. Судя по моим исследованиям, FirebaseListAdapter имеет встроенную функциональность для решения этой проблемы. Однако я не могу заставить свой код распознавать класс FirebaseListAdapter. Как заставить FirebaseListAdapter работать?
