Struggling to swap my Android SDK to 25.2.3

I had to build anew machine and have (tried) to follow instructions as per Mobile | Meteor Guide

BTW, I am using Meteor 1.6.1.1 also trying Meteor 1.7

But can’t seem to swap out my Android SDK version to 25.2.3
I downloaded the zip, and replaced it in the tools directory.

See below… still refers to 25.3.x … so my changes don’t seem to have been picked up

Does anyone have any specific line by line instruction on how to do this, please?

BTW, I got this workings as per https://github.com/meteor/meteor/issues/8464 many moons ago… just strugglinig to get this going on a new OSX machine.

I tried to uninstall the latest Android Studio and reinstall an older version eg 3.0.1
