Android 10 에서만 Crash 되는 JNI Bug

0 추천

안녕하세요.
현재 안드로이드 APP 을 마켓에 올려 운용중입니다.
TargetSDK 는 28 이구요.
매번 발생하는 버그는 아니지만, 특정 상황에서 계속 나오는데 JNI 버그라 추적에 한계가 있어 도움 요청드립니다. 버그 발생 조건은 안드로이드 10 사용자 폰에서만 나타나고, 이러한 유형의 버그가 대부분 리포트 됩니다.아래 로그를 공유해 드리니 , 고수님들 확인 및 답변 부탁드립니다.

다른 건 모르겠고, Cause: null pointer dereference인 걸로 봐서는, 레퍼런스를 해제하려다가 해당 instance가 null이 되어서 생기는 문제 같습니다. 액티비티나 프레그먼트가 종료될 때 널이 될 가능성이 있는 녀석이 있는지 확인해 보세요. 예를 들면 앱이 백그라운드에 있을 때 프로세스가 죽었다던가.
