I'm writing gesture order recognition project，want to realize automatic focusing hand function，but i don't know how to realize, will you provide advice, it is best to provide the relevant code, and how about android platform?
Here is a good starting point:
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3231510/
It describes focus algorithms and helps you go into the field.
However, you should know that usually, the functions needed to control the camera to provide auto-focus are not available for camera phones. They are usually embedded as OS drivers or even in-camera embedded software.
Some search pointed me to this:
