If you know a thing or two about Android, and a free trip to the next TED conference is your kind of thing, then the app developers at Snaptic may have just the contest that you've been looking for.

The competition in question, Snaptic's "Move Your Apps" developer challenge, calls on Android developers to create new applications that move users to move. Co-sponsored by the non-profit HopeLab — which works to improve the quality of life for young people with chronic illness — the challenge will reward coders who come up with unique ways of promoting activity via Android apps.

The competition, which will run through May 21st, promises one lucky winner an all-expense paid trip to the exclusive TEDGlobal 2010 conference, to be held in Oxford, England from July 12 - 16, 2010. TED — Technology, Entertainment, Design — describes itself as "bring[ing] together the world's most fascinating thinkers and doers, who are challenged to give the talk of their lives."

The contest is open to all developers who meet the following criteria:

• Meet the challenge and build an Android app (.apk) that inspires and tracks physical movement.
• Use a Snaptic intent or something from the Snaptic API
• App is already in the Android market? It must have under 5,000 downloads at the time of submission.
• If you're under 18, we need you to get us a signed consent form.
• Register by May 18th, 2010, submit by May 21st, 2010!

Entries will be judged by a committee of seven, with scoring based on an even split between the application's technical features, its appeal to users, and how well it meets the goal of inspiring movement. Winners will be announced on May 27th.

More information about the challenge, including official rules, documentation, and technical support from Snaptic, is available from Snaptic's website.
