/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.targets(506,2): error XA5207: Could not find android.jar for API level 28. This means the Android SDK platform for API level 28 is not installed. Either install it in the Android SDK Manager (Tools > Open Android SDK Manager...), or change the Xamarin.Android project to target an API version that is installed.
