Background

A friend and i were discussing if it was possible and after some moderate research and multiple days of testing different alternatives i came up with the next guide

Clarifications

Why a PRoot container? i tried to run raw java binaries on termux without the container and they are just a pain to deal with, also, termux only officialy supports java 17 through their repos which won't even let you play on the latest minecraft version
I will be using a program called playit.gg because it allows you to use your phone as a Minecraft server that can be accessed from anywhere (i like things simple). If you do not install this program, You will not be able to access your server through any device outside of the phone’s LAN network unless you use another method for Port forwarding. Feel free to share alternatives for Port forwarding!

Recomendations: Connect a Keyboard to your phone, Make an Account on Playit.gg beforehand

Instructions

Step 1. Install Termux

Step 2. Create a Fedora PRoot Container inside termux

(Command Extracted from AnLinux, playstore)

pkg install wget openssl-tool proot tar -y && hash -r && wget <https://raw.githubusercontent.com/EXALAB/AnLinux-Resources/master/Scripts/Installer/Fedora/fedora.sh> && bash fedora.sh

And enter the Container by typing:

./start-fedora.sh

NOTE: I choose Fedora because it is what i like the most.

(Optional) Step 2.1 Tweak dnf for Speed

For this, open a terminal and type:

printf 'max_parallel_downloads=10\\nfastestmirror=true' >> /etc/dnf/dnf.conf
