♨️onFailure: 통신실패 : CLEARTEXT communication to localhost not permitted by network security policy

http 요청을 막은 것. https 는 해당 없음

내 AVD 에서는 서버 주소를 (localhost ) 요청하는게 불가능함

따라서 ipv4 주소를 적어준뒤 :포트번호 해줌

그래도 이 오류가 떠서 찾아보고 일케 설정해주니 통신은 성공

타입이.. 타임스탬프라서 오브젝트로 변환하는 과정에 오류가 남

이제 이걸 timestamp 로 바꿔줄건데......험난한 여정...
