Dan Morrill, a ‘Developer Advocate’ has posted some information on the official Google Android Blog, including the link to submit your project to the Android Developer Challenge. It should be noted that you can submit as an individual, team, or as a corporation. Dan is very excited about the challenge and offers some interesting tidbits about it. For instance, you can submit your application now, and then again later should you refine it.
The submission period is open until March 3, 2008, so you don’t need to rush to submit your application just yet. March 3 is definitely a hard deadline though, so you must have your applications submitted by then. If you choose to submit now, you can always re-submit a later version of your application closer to the end.
