Firebase dynamic link (다이나믹 링크) (3/4)

• 이제 기본적인 설정 및 테스트를 완료하였으므로 구현 코드를 보자

• 상황에 따라 호출되는 포맷이 다르므로 주의하도록 한다.

 

• 앱이 설치되어 있고 웹링크를 통해 호출된 경우 :

https://appname.page.link/?link=https://com.company.appname/testlink?param=XXXXXX ...

 

• 앱이 설치되어 있지 않아 스토어에서 설치된 후 실행된 경우 :

com.company.appname://google/link/?deep_link_id=https://com.company.appname/testlink?param=XXXXXX ... &match_message=Link is uniquely matched for this device.
