How does stacktraced native crashes make sense? How can I understand where to fix?

News & General Discussion

Hello.
We have just implemented a module to download our mini games from Firebase Storage with web requests.
Upon testing it we noticed that only one of our test phones (Samsung A71) crashed.
From Android Logcat we were able to get the native crash log and immediately stacktraced it to get more ideas on the potential fixes.
But we are stuck now because we couldn’t be able to comprehend this crash log easily.
What does cause this crash?
What must I do more to uncover what casuses it?

That’s below “backtrace” column.

It crashed within “UnityEngine::Analytics::SuitePerformanceReportingConfigkUnitTestCategory::Fixture::ConfigChanged”

But that looks like a part of test reporting function, so the actual problem could’ve appeared above that point.
For example in “SuiteBitUtilitykUnitTestCategory::TestMath_HighestBit32”

To lcate the problem, assuming you can’t attach a debugger to it, you’d need your application to LOG a ton of messages, and the last one before the crash will be close to the problematic part of it.

How can we attach a debugger? I don’t know how to use debuggers specifically with this native crashes? I have only used Logcat to understand this problem.
And thank you for this insight. If I couldn’t handle it with attaching a debugger, I would try to log messages before the functions.

See here “Debugging on android devices”

Basically, your ide should allow you to attach to an android device, if you connected it via usb, enabled developer mode (stay awake, usb debugging), and if you’re using a development build. I beleive it should also work on IL2CPP build.

If that works, then you should be able to debug the application step by step from your PC.

If it doesn’t, well, you’ll have to read debugging messages.
