You can't use connector compiled for Scala 2.11 with Spark 3.2.0 that is compiled with Scala 2.12. You need to use appropriate version - right now it's 3.1.0 with coordinates com.datastax.spark:spark-cassandra-connector_2.12:3.1.0

P.S. Please note that although basic functionality will work, more advanced functionality won't work until the SPARKC-670 is fixed (see this PR)

Tried to apply BOM to sync dependencies
Tried to upgrade/downgrade android build plugin

So, after few days of digging around I have found a solution. So, to make it work I had to:

Downgrade Android Gradle Plugin to 3.5.3 version
Downgrade Gordon plugin to 1.0.6 version
Migrated fabric-crashlytic to firebase-crashlytic. With adding plugin of the last as well, otherwise, errors occur.

All other updates could be set, but this 3 items have to be sticked to the versions mentioned.
