Android SDK missing

I have 26 installed according to the SDK Manager in Android Studio.

However, when I’m following the quickstart guide, Unity complains that I don’t have it installed.

Any advice appreciated. This is on Ubuntu 20.04, thanks!

There are different possible solutions, but probably the easiest way is to make sure that UNity is using that SDK.

1.Uncheck using the SDK from Unity in Edit → Preferences → External tools
2.Add the path to the Android Studio SDK in the SDK field
