I understand that Firebase does not support android devices that do not have google services installed. I'm trying to build a native android app on a Clover Till (https://docs.clover.com/). I need realtime database and authentication. The rest of the firebase features would be nice however I can get by with just the database and authentication.
It seems like realtime database is working but authentication is not. Am I correct in saying that firebase auth needs google services to work in android? If so, what are my options? Could I build a hybrid app to get around this? Thanks
