Проблема с инъекционной деятельностью (Dagger2)

0 голосов
/ 16 февраля 2020

Я пытался внедрить свою активность, и по какой-то причине она, похоже, не работает. Кажется, это не работает, если я расширяю свою деятельность из DaggerAppCompatActivity или напрямую внедряю HasAndroidInjector в свою деятельность.

Ошибка
