Kotlin IllegalAccessError Problem

[HarryTylenol]

I got IllegalAccessError when my RecyclerAdapter is Kotlin.
It says "Illegal class access", "declaration of 'My Adapter Class' appears in ...base.apk:classes2.dex"

But when I change my class to java, It works fine.

java.lang.IllegalAccessError: Illegal class access: 'cupid.android.ui.adapter.HomeFragmentAdapter' attempting to access 'com.ahamed.multiviewadapter.BaseDataManager' (declaration of 'cupid.android.ui.adapter.HomeFragmentAdapter' appears in /data/app/cupid.android-1/base.apk:classes2.dex)

Thanks for raising this issue. There is an open PR #23 to fix this. I am currently reviewing the PR and soon release a new version.
