 # android-map-notification
+## Step 1. Splash Screen
+### 구현 기능 목록
+
+1. 초기 진입 화면 추가
+2. Firebase의 Remote Config 설정
+   - 서비스 상태 나타내는 매개변수 각각 등록
+     - 매개변수 이름: serviceState, serviceMessage
+3. 매개변수 serviceState 값 = ON_SERVICE
+   - 초기 진입 화면 -> 지도 화면
+4. 매개변수 serviceState 값 != ON_SERVICE
+   - 지도 화면 진입 X
+   - serviceMessage 값 -> 초기 진입 화면 하단에 표시
+5. 상태 관리
+   - 서버 상태
+   - UI 로딩
+6. MVVM 아키텍처 패턴 적용
