Tabbed Template

This is a bare bones tabbed template mobile app using NativeScript and Angular. It has been stripped down from the actual app I am working on.

I have been working on it in Android.

It was building and running in NativeScript 6.5.0 and I have migrated to NativeScript 8.1.5 and am trying to get it building and running but stuck.

Fork/clone and

ns run android

This is how it should look.

This is the error message I am now stuck on
