Amazon Fire Tablet: Unable to register application.. please check to ensure you have the mobile_app integration

I’m trying to install Home Assistant on my son’s Amazon Fire tablet. Is this error caused because the Amazon tablet doesn’t have google services installed? If so, what specific components are needed to get this app installed on his tablet?

I know there’s an Amazon Fire Toolbox that lets you install google services on this kind of tablet. However, I didn’t want to do this unless that’s the only way to do it.

The only way I was able to get Home Assistant to install and work correctly was installing Google services via Amazon Fire Toolbox. It worked like a charm.
