Installing MusicBot on Android requires manual setup, some technical knowledge, and of course time.
Android is not officially supported primarilly due to lack of contributors who use the environment.
The following steps may be completely incorrect or wildly out-of-date!

Install Steps

First, install Termux on your device.

After your terminal is installed, you can run the following commands to start getting setup:

# Update system packages first.
pkg update
pkg upgrade

# Install system dependencies.
pkg install glib libffi cmake python git ffmpeg deno

# Switch to your home directory.
cd ~

# Clone the dev branch of MusicBot into a folder called 'MusicBot'.
git clone https://github.com/Just-Some-Bots/Musicbot.git MusicBot -b dev

# Now enter the MusicBot directory.
cd MusicBot

# Install python dependencies for MusicBot.
python -m pip install -U -r requirements.txt

Following this setup, you can configure the bot and then run the bot with ./run.sh

Since Termux and Android are not officially supported, it is recommended to cofigure your DebugLevel option to EVERYTHING while getting set up and troubleshooting.
