About

This repository is a guide on how to open a minecraft java server on an android device, with root access.
Using Termux to manage the server, Ngrok to share localhost, and Magisk to edit the host file.

prerequisites

• A smartphone with at least 4Gb of ram
• Magisk-root solution for android devices
• Termux-a terminal for android devices
• Ngrok-a solution to share your localhost
• Minecraft_server.jar-file to open the server

Starting

In termux you will need the following packages:

• openjdk17
• wget

pkg install openjdk-17 wget
pkg update 

Permission for termux to access internal and external memory

termux-setup-storage

Setup Ngrok

Be sure of your CPU architecture.
If it is arm64

wget https://bin.equinox.io/c/bNyj1mQVY4c/ngrok-v3-stable-linux-arm64.tgz

If it is arm

wget https://bin.equinox.io/c/bNyj1mQVY4c/ngrok-v3-stable-linux-arm.tgz

After downloading, unpack with

tar xvzf ~/ngrok-v3-stable-linux-arm"architecture".tgz

Add your ngrok authtoken

./ngrok config add-authtoken <token>

Ngrok installed

Edit hosts file

In magisk settings enable systemless hosts and restart your smartphone
Open termux and give root access permission

su

Edit the hosts file using text editor

nano /data/adb/modules/hosts/system/etc/hosts

Add these lines at the end of the file

8.8.4.4 dns.google.com
52.217.137.128 s3.amazonaws.com
3.136.132.147 tunnel.us.ngrok.com
54.161.241.46 update.equinox.io

Note: you can change the ip's, just use a website to look up the ip from those DNS.

Open minecraft server

Create a folder inside your internal memory and place the server.jar file in it
Now with all the steps done, go back to termux

Joining the server

Now just copy the ip that is in the ngrok tab, in the Forwarding line

Example: 0.tcp.sa.ngrok.io:16040

You now have a minecraft server open
