강의 듣다가 아래와 같은 오류가 발생하고 에뮬레이터 상에서 사진처럼 저런 에러가 발생했습니다
저 부분 말고 나머지 기능은 전부 다 실행이 되는데 어떻게 해결해야 될까요..
구글링을 해봐도 해결방법을 모르겠어서 남깁니다 ㅠ

검색해 보니 minSdkVersion 21 이상으로 설정하면 해당 에러가 사라지는 것 같습니다.

해결했습니다!
마지막으로 하나만 더 질문하려고하는데
Plugin project :firebase_core_web not found. Please update settings.gradle.
Plugin project :cloud_firestore_web not found. Please update settings.gradle.
