[Android] 버전 맞추기, 구현 가능했던 build 설정들

Kotlin releases | Kotlin

kotlin의 버전이 너무 낮다는 오류가 떴다. android 쪽은 Firebase나 NaverMap 같이 외부 api를 쓸 경우 버전 때문에 생기는 에러가 꽤 많은 편이다. 계속 최신 문서 보면서 버전 업데이트 해줘야 한다.

• kotlin 부분 com.kotlin.android ... 이런식으로 되어 있는 부분 변경
• jvm target 인식 못해서 숫자 "11" 넣어서 변경
• minSdk 숫자로 변경 (23) 외부 api들과 충돌되었던 부분이다.
