위치 검색 지도 앱

주요 기능

• POI 기능 사용해 retrofit을 통해 가져온 response 바디를 Gson으로 파싱해서 사용
• 검색화면에서 받아왔던 데이터를 intent로 넘겨받아 GoogleMap을 통해 마커로 지도 위치 표현
• 본인의 위치 데이터를 POI API를 통해 현재 내 위치 정보를 가져와 Gson으로 파싱해 데이터를 다시 한 번 마커를 통해 뿌려줌
  
  

사용 기술

• GoogleMap poi
• Coroutine
• Retrofit
• OkHttp

새 프로젝트를 생성하고 사용자 인증 정보 만들기 항목에서 API키를 생성한다.
애플리케이션 제한사항에서 'Android앱'을 선택하고 앱 패키지명과 SHA-1 서명 인증서 디지털 지문을 입력한다.

cmd 창에서 "C:\Program Files\Android\Android Studio\jre\bin\keytool" -list -v -keystore "%USERPROFILE%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android 의 명령어를 입력하면 SHA-1 코드가 나타난다.

생성된 API Key를 AndroidManifest.xml 파일의 application 태그 안에 아래와 같이 추가해준다.
