It seems you need to import the support library

go to your app>build.gradle in dependencies

dependencies
implementation 'com.android.support:design:27.1.1'


Can you please post the layout xml files for @layout/navigation_action & @layout/content_scan.
I think you are having some vector drawables issues for pre-lollipop devices within these layout files.
