어쩌면 여기에 내 소스 코드가 필요할 수 있습니다.

정보 메시지를 읽는 동안 나에게 이것에 대한 아이디어를 제공 Conscrypt하고 연구를하고 conscryptgradle.app 에 설치해야한다는 것을 알았습니다.
implementation 'org.conscrypt:conscrypt-android:2.2.1'작동합니다.
답변
OkHttp는 Conscrypt 보안 라이브러리와 호환되지만이를 사용하는 것은 선택 사항입니다. 스택 추적은 무섭지 만 Conscrypt 종속성을 찾을 수 없다는 경고 일뿐입니다. 이 경우 OkHttp는 플랫폼의 기본 TLS 구현으로 폴백해야합니다.
에서 OkHttp의 README :
OkHttp는 플랫폼의 내장 TLS 구현을 사용합니다. Java 플랫폼에서 OkHttp는 BoringSSL을 Java와 통합하는 Conscrypt도 지원합니다. OkHttp는 Conscrypt가 첫 번째 보안 제공 업체 인 경우 다음을 사용합니다.
Security.insertProviderAt(Conscrypt.newProvider(), 1);
간단히 말해 네트워크 요청이 작동하면이 스택 추적을 무시하는 것이 안전 할 것입니다.
