Work Description ✏️

  • FCM 푸시 알림 기능을 세팅했습니다. (기존 Firebase Analytics 세팅 위에 Messaging 추가)

  • SDK 배선: firebase-messaging 의존성 추가, POST_NOTIFICATIONS 권한 및 FCM 수신 서비스·기본 알림 메타데이터(아이콘/틴트/채널) 매니페스트 등록

  • 알림 코어 (core/notification, Analytics와 동일한 인터페이스/Hilt 패턴)

  • NotificationChannels — 기본 알림 채널 생성 (앱 시작 시)

  • MoballMessagingService(@androidentrypoint) — onNewToken(토큰 갱신 재등록) / onMessageReceived(알림 표시)

  • MoballNotifier — 알림 빌드·표시, 탭 시 MainActivity 실행

  • FcmTokenRegistrar — FCM 토큰 조회·서버 등록 진입점

  • RequestNotificationPermissionEffect — Android 13+ 런타임 알림 권한 요청

  • 토큰 동기화 타이밍: 신규 로그인(LoginViewModel) / 자동 로그인(SplashViewModel) 성공 직후 syncToken() 호출

  • 알림 리소스: 상태바용 흰색 야구공 아이콘(ic_notification), 액센트 컬러, 채널 문자열 추가

Screenshot 📸

Uncompleted Tasks 😅

  • 토큰 서버 등록 API 연동 — 백엔드 엔드포인트 미확정. UserService~Repository까지 뼈대만 준비했고, UserRepositoryImpl.registerFcmToken()의 실제 호출은 TODO(#알림)로 주석 처리(현재 no-op). 백엔드 나오면 경로 확인 + 주석 한 줄 해제
  • 서버 → 클라이언트 알림 payload 스펙 확정 (data-only vs notification, title/body 키)
  • 알림 탭 딥링크 (현재는 MainActivity만 실행 — 펍 상세/일정 등 이동 필요 시 확장)

Summary by CodeRabbit

  • 새로운 기능
    • 푸시 알림 수신 및 시스템 알림 표시 기능을 추가했습니다.
    • Android 13 이상에서 알림 권한을 요청합니다.
    • 로그인 및 자동 로그인 후 기기 알림 토큰을 동기화합니다.
    • 알림 채널을 자동으로 생성하고, 알림 선택 시 앱을 열 수 있습니다.

📝 Walkthrough

Walkthrough

FCM Messaging 의존성과 알림 구성을 추가했다. 앱 시작 시 채널을 생성하고 Android 13 이상에서 권한을 요청한다. FCM 메시지를 시스템 알림으로 표시하며, 로그인 완료 후 FCM 토큰을 조회하고 등록한다.

Changes

FCM 알림 런타임 구성

Layer / File(s) Summary
알림 의존성 및 시스템 구성
app/build.gradle.kts, gradle/libs.versions.toml, app/src/main/AndroidManifest.xml
Firebase Messaging 의존성, 알림 권한, FCM 서비스, 기본 아이콘·색상·채널 메타데이터를 추가했다.
채널 초기화 및 권한 요청
app/src/main/java/com/moball/app/MoballApp.kt, app/src/main/java/org/app/core/notification/NotificationChannels.kt, app/src/main/java/org/app/core/notification/NotificationPermission.kt, app/src/main/java/org/app/presentation/main/MainScreen.kt
앱 생성 시 기본 알림 채널을 생성한다. 메인 화면 진입 시 Android 13 이상에서 알림 권한을 요청한다.

FCM 메시지 수신 및 표시

Layer / File(s) Summary
메시지 처리 및 알림 생성
app/src/main/java/org/app/core/notification/MoballMessagingService.kt, app/src/main/java/org/app/core/notification/MoballNotifier.kt
FCM 메시지의 notification 또는 data 페이로드에서 제목과 본문을 읽는다. MoballNotifier가 권한과 기본 채널을 확인한 후 MainActivity 실행 인텐트를 포함한 알림을 표시한다.

FCM 토큰 서버 계약

Layer / File(s) Summary
토큰 API 계약 및 데이터 계층 연결
app/src/main/java/org/app/data/remote/dto/PostFcmTokenRequest.kt, app/src/main/java/org/app/data/remote/service/UserService.kt, app/src/main/java/org/app/data/remote/datasource/api/UserRemoteDataSource.kt, app/src/main/java/org/app/data/remote/datasource/impl/UserRemoteDataSourceImpl.kt, app/src/main/java/org/app/data/repository/api/UserRepository.kt, app/src/main/java/org/app/data/repository/impl/UserRepositoryImpl.kt
FCM 토큰 POST 요청과 저장소 메서드를 추가했다. 저장소 구현은 현재 API 호출 없이 토큰 일부를 로그로 기록하고 성공을 반환한다.

인증 완료 후 토큰 동기화

Layer / File(s) Summary
토큰 조회 및 인증 흐름 연결
app/src/main/java/org/app/core/notification/FcmTokenRegistrar.kt, app/src/main/java/org/app/presentation/onboarding/login/LoginViewModel.kt, app/src/main/java/org/app/presentation/onboarding/splash/SplashViewModel.kt
FcmTokenRegistrar가 토큰을 조회하고 등록한다. 로그인 성공과 자동 로그인 성공 후 동기화를 호출한다.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to e4ff4

FCM token synchronization currently does not contact the server but still reports success, so users may fail to receive server-triggered notifications even after enabling notifications or logging in. Merge should wait for the registration contract and real API call to be enabled, or for this limitation to be explicitly accepted; token logging and permission-request behavior also need follow-up.

scope의 소유 수명을 명시하세요.

부모 없이 생성한 SupervisorJob()에는 명시적인 취소 경로가 없습니다. 앱 수명 작업이면 @ApplicationScope로 지정한 CoroutineScope를 DI로 주입하세요. 호출자 수명에 종속되는 작업이면 register를 suspend 함수로 변경하고 소유자의 viewModelScope 등에서 호출하세요.

In `@app/src/main/java/org/app/data/repository/impl/UserRepositoryImpl.kt`:
- Line 56: Update the FCM token logging in UserRepositoryImpl so it records only
the registration status and removes token.take(12) and any token-derived value
from the Timber.d message.
- Around line 51-57: Update registerFcmToken in UserRepositoryImpl so it no
longer returns success after only logging; until the backend endpoint is
available, explicitly return a failure, and once the API contract is ready,
enable userRemoteDataSource.postFcmToken(token).checkSuccess() to perform the
registration.

In `@app/src/main/java/org/app/presentation/main/MainScreen.kt`:
- Around line 81-82: Update MainScreen and RequestNotificationPermissionEffect
to preserve the notification permission request state with rememberSaveable
across configuration changes. Pass the state into
RequestNotificationPermissionEffect and update it immediately before launching
the permission request, while retaining the existing Android 13+ and one-time
request behavior.
