just playing with Xamarin... I've made a simple WebView app, only one view that has a WebView component and loads an external HTML page.
When I compile the app for release, setting "Linking: Sdk Assemblies Only" I get a 18MB APK! 
By reading the guide page here at developer xamarin.com>"application_package_sizes" the APK should be very much smaller!
What I'm doing wrong?
