Android Developer Challenge 2 open for submissions

Tweet

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 If your apps depend on unpublished APIs, they might not work on some of these phones.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.

Android Developer Challenge: Round I Results are In

Tweet

The last few weeks were both extremely intense and rewarding. Based on feedback from the judges, it was apparent that large number of applications were compelling, innovative and well implemented. The quality of these entries clearly reflects the creativity and hard work that developers have invested in building their apps.

In addition to developers' participation and contributions, over 100 industry judges around the world spent weeks reviewing these submissions. I want to thank all the developers and judges who have worked incredibly hard over the last few months, making the Android Developer Challenge such a success.

Many of the top submissions took advantage of the geo and social networking capabilities of Android. These applications allow friends to share their personal experiences and favorite content such as vacations, photos, shows, music, cooking recipes, restaurants, and much more as they relate to certain locales. I've also seen applications that connect people during emergency situations and others that allow users to share information on how they can reduce their carbon footprint. One developer even turned a real city block into a playing field where gamers can role-play and chase after villains.

Furthermore, some of these applications provide rich interactive experiences by combining web services and mash-ups to bring together data that's on the web with data that's on the mobile device. One application combined weather, pollen and allergy information in the context of a map that is relevant to a user's location.

Though many applications use a traditional "download" model for data, many also enable users to publish content, such as photos or even voice memos, for others to use on other mobile devices or the web.

This is just a brief snapshot of the many impressive applications I've seen. The 50 highest scoring applications will receive $25,000 each and go on to compete in the final round. We plan to publish a list of these applications as soon as we receive the developers' consent. The real winners, however, are the consumers who will benefit from the work of these talented developers.

The Android Developer Challenge is proceeding nicely. We're excited about the interest people have shown so far and have enjoyed talking to everyone working on new Android Apps.

As a quick reminder, the first phase of the challenge will be ending on April 14. In the Android Developer Challenge I, the 50 most promising entries received by April 14 will each receive a $25,000 award to fund further development. Those selected will then be eligible for even greater recognition via ten $275,000 awards and ten $100,000 awards.

Keep working on your applications, and be sure to post in the forums if you have any questions!

Android at Google I/O and Developer Days

It was great to connect with everyone at the Google I/O event in San Francisco and at our recent Developer Days across the globe. We enjoyed meeting all of the Android developers and answering your questions - both at our booth and at the fireside chats.

For those of you who were unable to attend, all of the sessions are available on video:
