microg/GmsCore ? reverse-engineered prompt

I want to build an open-source replacement for Google Play Services for my Android phone. The goal is to be able to run regular Android apps that depend on Google's services, but without having the official Google software installed.

My main priorities are getting core features to work, like push notifications, location services for maps and other apps, and authentication so I can log into things. Basically, I'm trying to re-create the 'microG' framework. It's a pretty big Java project for Android, and it seems to have a lot of different modules for things like Firebase, maps, and safety checks. You'll need to set up the build to create the core services framework that can be installed on an Android system to make other apps function correctly.
