Its actually possible to mod on Android, I actually made an account just for this unfortunately my comment doesn't get approved by mods and im lazy to rewrote it again (yea I had tried to mod it on android a year ago) 

Btw you just need Godot ver 3 on android and download bdcc-main zip on github, unpack it and link the unpacked file on the godot. The rest is tutorial you can follow that rahi provided, or just look into someone's mod
