I'm attempting to build my first F# Android project in Visual Studio 2017 (Community Edition).

Immediately after creating a new project by using the F# - Android - Blank App template, the error window in Visual Studio displays the following message:

  
The project Foo is missing Android SDKs required for building. Double-click on this message and follow the prompts to install them.

No amount of double-clicking on the message causes prompts to appear.

I can't find an obvious place to download the Android SDK from:

The SDK manager that I remember from a while ago seems to have disappeared from the Android developer website.

I've installed Android Studio, which seemed to download some Android SDKs, but Visual Studio still can't seem to find whatever it's looking for.
