Ошибка выполнения для задачи ': app: processFirebaseDebugGoogleServices'

Question

Когда я создаю свое приложение в студии android, оно выглядит так.

Build Output :


FAILURE: Build failed with an exception.

What went wrong:
Execution failed for task ':app:processFirebaseDebugGoogleServices'.
File google-services.json is missing. The Google Services Plugin cannot function without it.
Searched Location:
D:\Github\ScreenStream-master\app\src\firebase\google-services.json

Я уже добавил com.google.gms: google -services: 4.3.3.
