android.content.res.Resources$NotFoundException
android.content.res.ResourcesImpl.getResourcePackageName
After upgrading Crashlytics from 2.6.6
It was happening for me as well. I couldn't reproduce it but after analyzing Crashlytics log history I realized it started happening after I moved to app bundle. So I moved back to apk and now I am not getting these issue anymore.
