경기대학교 컴퓨터 공학도로서 코틀린(안드로이드 스튜디오)실력 향상을 위한 프로젝트로서 당근마켓을 모티브로 중고거래 어플을 제작해보는 여름방학 프로젝트
-
-
2017년 구글 I/O에서 공식언어로 지정된 코틀린을 이용하여 어플을 개발하며 코틀린 언어 공부 및 실력 향상.
기존 중고거래어플의 대면거래시 범죄의 취약함이 드러남에 따라 비대면으로 거래할 수 있도록 기획함
-
안드로이드 스튜디오를 사용하여 회원, 상품, 채팅을 FireBase를 연동하여 구현
FrontEnd 부분은 BottomNavigation을 이용하여 Activity와 Fragment를 적절히 섞어 사용.
-
현재 구글맵을 통해 사물함 마커를 찍어놨고, 추후에 사물함 예약등 비대면거래 플랫폼 추가 예정

-
- 중고거래마켓 어플 구현 (회원가입/로그인/상품등록 및 삭제/채팅/지도/회원정보관리)
-
- FireBase 연동을 이용한 로그인 및 회원가입 구현
- Activity와 Fragment별로 각 항목을 나누어 구현
- 이메일 인증을 통한 회원가입
-
- 개발 툴 : Android Studio
- DB : Firebase-Authentication, Firebase-RealtimeDatabase, Firebase-FireStore, Firebase-Storage
- API : Marshmallow
- GoogleMap API 사용
-
-
매일 한 기능씩 할당량을 정해놓은 후, 일주일에 주말을 제외한 3~5일 미팅을 가지며 프로젝트 진행
-
