This is a total shot in the dark. I have an APK that is a plugin to another APK and running into an issue with okhttp3 obfuscated on Android 8.0. Get an IncompatibleClassChangeError for kotlin.collections.AbstractList. A couple methods are removed at runtime looks like. Wondering if anyone has ever seen this on Android 8.0 and figured how to work around it. Later versions of Android don't have an issue.
