The author has integrated automated glass into Minecraft for Android, but the Connected Glass mod does not replace vanilla glass blocks, but gives alternative ones.
You can get a new glass in the game with the help of crafting or creative inventory. In Minecraft, all standard glass options, both transparent and colored blocks, will be available on the phone.
You will no longer need to use commands in Minecraft PE, as the Connected Glass mod will connect glass blocks located nearby automatically. Thus, you can at least glass the entire map, because everything will be simple and convenient in Minecraft on a tablet. Enjoy it!
