I managed to run MCServer under Android with some trick's.

That's awesome I didn't know an app existed that allowed you to install Linux on Android. We previously did have an actual app for Android, but lately it doesn't compile anymore.

Yea, it's using a chroot method to run linux, and this is not emulation, speed is the same as android on the same device (the one of developer of linuxonandroid app said this to me).
And, I know that android builds are broken, so I came with nice solution ^^
