위의 로그와 함께 많은 오류보고가 Fabric에보고되었는데,이를 이해하고 해결책을 찾을 수 있습니까? 많은 장치에서 테스트를했지만 위의 로그를 생성 할 수 없습니다. 7 일 이내에 Fabric console에 약 300 개의 오류보고가 있습니다. 방금 새 업데이트에서 CrashlyticsNdk()을 사용하도록 설정했습니다. 누구든지 문제를 식별 할 수 있도록 도와 줄 수 있습니까?

감사합니다.

Answer 1

, 내 JNI 코드

이전 코드

char signToken[endingNumber - startingNumber]; 
    int at = 0; 
    for (int i = startingNumber; i < endingNumber; i++) { 
     signToken[at] = cstr[i]; 
     at++; 
    } 
    signToken[at] = '\0'; 

새로운 코드

char signToken[endingNumber - startingNumber + 1]; 
    int at = 0; 
    for (int i = startingNumber; i < endingNumber; i++) { 
     signToken[at] = cstr[i]; 
     at++; 
    } 
    signToken[at] = '\0'; 

에서 버그를 발견 한

부분 문자열에 대한 간단한 로그인입니다. 여기서 문자열 크기는 strin의 길이와 같습니다. g하지만 크기를 N + 1로 업데이트 한 후 문자열의 길이가 +1 인 경우 문제가 해결되었습니다.

Answer 2

이전 버전이 있거나 gralloc.rk30board.so 파일에 문제가 있다고 생각되면 업데이트해야합니다. 시도하십시오 This 희망이 도움이 될 것입니다. :) 나는 긴 디버깅 후 내 자신의 질문에 대답하고 여기
