아래는 캡쳐본이랑 MainActivity 전체코드입니다.

회원가입을 하면 아래 계정이 회원가입은 되는 것을 Firebase에서 확인했지만,

토스트메시지가 안떠요 ("ok", uid 확인 등 아무것도 안뜹니다)

안녕하세요

저 Toast 메세지가 안나오는 문제가 가끔 에뮬레이터 문제일때가 있습니다.

에뮬레이터를 처음 만드셨던 것 처럼, 새롭게 만들어서 진행해보시겠어요?

(새롭게 만들어도 안되시면 한번 더 질문 남겨주세요)

그리고 System UI ~ 이 메세지는 에뮬레이터 성능 이슈인데 신경쓰지 않고 진행하셔도 무관하지만 해결하고 싶으시면 아래의 글들을 참고해주세요.
