Failed to export signed app due to lint warnings

I want to export a signed app, but after the error Lint comes up every time to stop me. How to clean it up. It's a lint-go-play-services error, so I tried Properties -> Android -> Android Lint -> Ignore All. but no effect. help me

This is mistake

This class should be publicly available (android.support.v7.internal.widget.ActionBarView.HomeView)

Problem. Ensures that classes registered in the manifest file are instantiable Id: Instantiatable

Actions, services, broadcast receivers, etc. registered in the manifest file must be "instant" by the system, which means the class must be public, it must have an empty public constructor, and if it is an inner class must be static inner class.
