error: failed linking references. -> QueuedJob

Question

I was studying the Android Material Design using Kotlin and everything was going fine until I tried to use the android.support.design.widget.FloatingActionButton.

Answer 1

Go to build.gradle(app) and add this in dependency:

implementation 'com.android.support:appcompat-v7:28.0.0'

Right now my compileSdkVersion is 28, so it is 28.0.0.

Try and change according to that.
