This class should be public (android.support.v7.internal.widget.ActionBarView.HomeView)
On the "v7-appcompat" library:
preferences -> Android Lint Preferences
Search for "Instantiatable" and set to Warning.
If you are using Eclipse:
Project > Clean > OKOr Try:
Preferences -> Android Lint PreferencesSearch for Instantiatable and set as Warning.

This worked for me.
Go to appcompat_v7 library -> Properties -> Android Lint Preferences -> Instantiatable -> Select "Warning" severity.
Instantiatable Summary: Ensures that classes registered in the manifest file are instantiatable
Priority: 6 / 10 Severity: Warning Category: Correctness
Activities, services, broadcast receivers etc. registered in the manifest file must be "instiantable" by the system, which means that the class must be public, it must have an empty public constructor, and if it's an inner class, it must be a static inner class.
