I'm going crazy.
I try to hide the home button on Android with Xamarin.Forms (should be build in). On iOS it wasn't a problem with a custom renderer. This doesn't work with Android. Not find any event, where to set home button attributes. So I created a DependencyService for doing this. When I call the method for hideing the home button with a button on the page, than it works perfect. The home button is hidden. But where to call this automatically? If I call it in OnAppearing of the page, the values are overwritten by Xamarin.Forms. I couldn't find any other place to call the functions. Also the custom renderer for NavigationPage hasn't a good event for this. So I could hide the home button but only by hand in a button event.
Any help is appreciated.
