Android SDK - Where to download the correct version

I’m running through the ToDos tutorial and I’m at the running on mobile section. I’m trying to install the Android Studio SDK Tools however I can’t figure out how to download the old version of the SDK. Meteor points to a page that as far as I can tell just gives me the versions, no download links though. Can someone help me out?

Make sure to select the correct version of the Android Studio SDK Tools:

Meteor or later: Android SDK Tools v.25.2.x
