Android Indoor SDK

I followed the tutorial to set up the Indoor SDK for Android from here:

The tutorial does not specify where most of the code should go (unlike the iOS tutorial) so most of it is in onCreate…but I’m receiving compile errors. I think the tutorial may be outdated.

Additionally, I’ve tried to get this portion working but cannot locate the LocationExtensionsKt class:
LocationPosition coffeeMachine = new LocationPosition(3.1, 7.2, 0.0);
if (LocationExtensionsKt.distanceTo(position, coffeeMachine) > 5) {
// Start brewing coffee
