Answer 1

I suggest using AndroidX instead of the old support library since it ensures better compatibility throughout libraries and api levels.

To start with that, add the following to your build.gradle

 implementation 'androidx.legacy:legacy-support-v4:1.0.0'

Also use the assistant: Refactor > Migrate to AndroidX

There might come up some errors at first but they should be fixed by replacing com.android etc with androidx instead and here are many posts to that topic.

Also you could try to directly address the Button using this inside the xml:

android.support.design.widget.FloatingActionButton

Hope this helps :) Good luck!
