Thanks for reporting this, @keepup.

May I know how this issue could be replicated so that we can identify what's causing this? Could you also confirm if your implementation is using the IL2CPP scripting backend?

[mrichards]

Hi @keepup & @AjayC-Bsw, it looks like the version of Crashlytics for Android didn't get updated with this release of our Unity SDK. The following workaround should resolve the problem:

Open Assets/Firebase/Editor/CrashlyticsDependencies.xml. Change the version of com.google.firebase:firebase-crashlytics-ndk:18.0.1 to 18.2.4.

This will cause the dependency resolver to download the correct version of the Crashlytics Android SDK, which includes the missing method identified in the error message. Subsequent builds should work as expected.

Our next release will include the correct dependency version, so this workaround will not be required in the future.

[solinvictus1313]

The workaround seems to work nicely. I still have to check the actual crash reporting functionality after this upgrade, but this brings me a lot closer. Thanks a lot @mrichards

We've just released a new version, 8.6.1, which has the correct Assets/Firebase/Editor/CrashlyticsDependencies.xml file. Thanks for bringing this issue to our attention.
