This question have been asked before but I am looking for solution for Unity platform. I tried to export project , had it opened on Android Studio but Gradle sync failed there too.

I have been using GoogeAds and Firebase in my project. The project builds well for IOS but for Android it gives me error "Deprecated Gradle features were used in this build, making it incompatible with Gradle 6.0".

I tried to delete everything in Plugins folder (except Template.gradle) but still got the same error.

So neither I am able to debug it on Android studio nor it is building on Unity. Any help or direction will be very beneficial.

I am using unity 2018.4.5f1

Thanks
