인프런 커뮤니티 질문&답변

안녕하세요.

혹시 잘 안되시는게 있으신가요?

전체 코드를 깃허브/구글드라이브에 올리시고 어떤 부분에서 안되시는지 설명해주시면 살펴보겠습니다~

notifiaction 관련 build.gradle에서 implement 추가하신거 지워보세요!

안녕하세요. 정말 죄송한데. 깃허브 사용법 보면서도 잘모르겠어서요.

 with(NotificationManagerCompat.from(this)){
            notify(123, builder.build())

notfity(123, builder.build()) 여기서 빨간 줄그어지면서 에러가 나는거 같습니다.
