Settings up Android SDK?

I’m trying to set up the Android SDK to develop a Cardboard VR game in Unreal, but even after following the steps in the quick start guide, I still get a message saying I’m missing stuff (with a link to that guide). I was hoping to get some help setting up for Android development. Thank you!

Update: I’m trying an install using NVidia Codeworks, because apparently I need that too, which wasn’t in the quick start.

The Unreal Documentation is no longer accurate, especially the quick start section. You have to gooogle NVPack, and get the NVidia Codeworks download and use those file paths. There is documentation for this, it’s just hidden in a different area.
