A few weeks ago I started a new Xamarin.Forms project and everything worked fine.
Now I wanted to continue working, but I always get the following errors when I try to build:
Error retrieving parent for item: No resource found that matches the given name 'android:TextAppearance.Material.Widget.Button.Inverse'. App1.Droid \GitHub\App1\App1\App1.Droid\obj\Debug\resourcecache\49D36360DD564E3F3469C621394FA704\res\values-v23\values-v23.xml 6
Error retrieving parent for item: No resource found that matches the given name 'android:Widget.Material.Button.Colored'. App1.Droid \GitHub\App1\App1\App1.Droid\obj\Debug\resourcecache\49D36360DD564E3F3469C621394FA704\res\values-v23\values-v23.xml 25
And this also happens in a completely new project! I just started to use Xamarin.Forms and Xamarin in general and would really appreciate your help.
