I want to extend the NavigationPage functionality by making it possible to add a background image to the navigation bar(iOS)/action bar(Android).
Therefore I have extended the NavigationRenderer for the NavigationPage.
I could do this for iOS, because the NavigationRenderer has access to the UINavigationBar.
But for Android I can't find out how to get the ActionBar from the NavigationRenderer.
How do I access the ActionBar in Android when extending the NavigationRenderer?
