With the image loaded in the Android project 'Resources/icon.png' as 'AndroidResource' or 'EmbeddedResource' and loaded like this:
this.Icon = "icon.png";
It just does not change anything. What am I missing?
EDIT: I tried this with a ContentPage (a NavigationPage), DetailPage (a NavigationPage) and MasterPage.
EDIT EDIT: Just found it,
