How to control gpio from Android application

Orion

As it says in the title is there a way to control the gpio from android application?
If you could point me to a tutorial or example code that would be great.

Im fairly new to programing with android so i have a few questions:
1. where do i find this code? do they exist in the android source code?
2. if they are not in the android source code, where should i create these files?
3.why name it luobo? or is this just the name of the person who created the program?
