Installing the Android SDK doesn't automatically include all the minimum required packages for developing. While individual developer needs vary, this guide discusses the packages that will generally be required for developing with Xamarin.Android.
This guide describes both the default settings of the Android SDK, which should work for most setups; and how to change these defaults in Visual Studio for Mac or Visual Studio if needed.
This article illustrates how to update the Java Development Kit (JDK) version on Windows and Mac.
