My friend and I have a Minecraft world on our Xbox that we would like to transfer to my android device is this possible and if so how?
No. Xbox stores Minecraft worlds in a different format than Pocket Edition. Maybe if you were a developer, but otherwise no.
If you wanted to play in that world on your Android, Minecraft now supports cross-platform multiplayer.
Unfortunately, at this time the only cross-platform capable versions are Windows 10 and Pocket Edition.
