Make sure Android Studio is not installed on your computer. If it is, uninstall it and run the Visual Studio installer again until all Android SDK errors go away.


Android Studio


Android SDK



Make sure Visual Studio is closed and install the most recent stable version of Xamarin for Visual Studio . I found it here: https://store.xamarin.com/account/my/subscription/downloads. (Trying to install it through VS didn't work for me under Tools -> Android -> Settings -> Xamarin for Visual Studio Updates.)



Make sure you have Java SDK version 7 installed on your machine. You also must use the 32-bit version even if you have a 64-bit machine. This was key!


Java SDK



Install the Android SDK. Standalone version, not Android Studio + Android SDK.


Android SDK



Install the Android NDK.


Android NDK



Restart your computer and open Visual Studio. Go to Tools -> Android -> Settings and set the correct paths to Android SDK, NDK and Java SDK.


Android SDK


NDK


Java SDK



You should be good to go with creating a new project.





I did it, but not done

You absolutely do NOT have to uninstall Android Studio... In fact you can use Android Studio to update the Android SDK, just point both IDEs at the some Android SDK location. Also the latest Android SDK version (and Xamarin's tools) work fine w/ Java 64-bit.
