I have seen many crash reports are reported on Fabric with above log, is there anyway to understand it and find the solution for it? I have tested on many devices but I am not able to produce above log. There are approx 300 crash reports on Fabric console within 7days. I have just enabled CrashlyticsNdk() in new update. Can anyone help me to identify the issue.

Thank you.

Answer 1

here I am answering my own question after long debugging, I have found a bug in my JNI code

old code

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

new code

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

it's simple login for a substring, where I have taken string size equal to a length of string but it's length of string+1 after updating size to N+1, I have resolved my issue.

I think you have an older version or have issues in file gralloc.rk30board.so you need to update it. try This Hope this will help you. :)
