It started with an idea to allow users to connect within polygon geofences anywhere on earth. Getting this system to work on Android with all the backend code takes a lot of time. The system itself loads polygon geofences 180° E and W longitude and 90° N and S latitude. And it uses perimeter-based loading system that crosses the antimeridian, equator and north and south poles.

I also built the entire user-based infrastructure from ground up in Java. That includes account settings, sign up, forgot and reset password, and verification codes with multiple settings.

But the framework itself is still more complex, allowing for very stable long-term Android applications. It includes dynamic configurations parsed from the database on the backend and then used on the backend and Android app via the commons library. Dynamic user messages. A full commons REST framework with REST processing that's in the commons library.

Overall it's a large system. And in fact, I'm getting close to publishing it so that users can build their own 100% Java full-stack Android applications: enterpriseandroidfoundation.com
