I believ this might be fixed in 2255, but the root cause is probabky a missing piece of the Android SDK

I’m referencing the one that ship with Visual Studio Mac. It look “green” in the preferences dialog. The first time it complain the folder “tools” was not present so I install it, then this happened.
