The time has come! The submission site for Android Developer Challenge 2 is now open. You can now submit applications for the Challenge at http://market.android.com/adc. Full instructions are also available on the site.
The key thing to remember is that all submissions must be entered by 11:59:59pm Pacific Time in the United States on August 31, 2009. If your applications are not submitted by that time, they won't be eligible for participation. Please carefully note what time that is in your local time zone.
It's very important that your apps only use published APIs. Some users might be judging your submissions on new phones you haven't seen or tested. If your apps depend on unpublished APIs, they might not work on some of these phones. Please note that you won't be able to submit new versions of your apps after the deadline!
Since you'll be competing against developers around the world for users' attention, it is important to focus on the fit and finish of your app. Your apps will be judged by users as a final product and not just a cool demo.
As a final note, if you've uploaded a version of your app to Android Market, you'll need to use a different Android package name for the version you submit to the Challenge.
I look forward to see all the great apps and innovations from you all.
