Don't forget to submit your ADC2 apps by midnight PST on Monday, August 31! Remember that this is Pacific time in the US (GMT - 7) so be sure to convert the deadline into your local timezone.
Also, even if you've already submitted your apps, please double check and make sure that your app is in the "Submitted" state in the UI! If it says "Unsubmitted", it will NOT be considered as an entry.
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 If your apps depend on unpublished APIs, they might not work on some of these phones.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.
London-based Acrossair recently rolled out its own take on the Augmented Reality (AR) story, by releasing an application that allows New Yorkers to point their iPhone camera at any city street and get an overlay of how close and in which direction the nearest subway stations are.
Hold the phone flat and it shows all the subway lines in coloured directional arrows.Raise the iPhone and it will point you to the nearest subway station, with distances shown.
You can see a quick demo video here:
Acrossair is clearly pitching itself against media darling Layar and, with its nifty new applications, muscling itself into position to grab some of the AR limelight.
Competition is clearly hotting up, not only in the US but also in Japan, where Tonchidot launched its own iPhone app, Sekai Camera that adds a social networking dimension to AR.
This definitely remains an area to keep close tabs on, with new smartphones enabling new consumer applications that were perhaps unthinkable until only a few years ago.
