Research direction
Explore Android's Wi Fi Direct and Bluetooth APIs for local multiplayer. Review existing network code in Unciv (likely using KryoNet or similar). Consider implementing a simple server hosted on one device that other devices connect to via local IP. Check comments in issue #14475 for any prior discussion or proposed approaches.
