Since the announcement of Android Developer Challenge 2 in May, Android phones continue to be deployed in countries worldwide. Android phones are currently available in over 20 countries, with more on the way. As I've mentioned earlier, we'll be including real-world users of these phones to help review and score your submissions. It is important to remember that your apps will be reviewed by judges around the world on actual devices; thus, be sure to make it extremely easy for users/judges to access your apps with minimum setup.
Some of you have been asking for clarifications on what we mean by "open only to applications that have not been published". To be specific, applications that are available on Android Market before August 1, 2009 will not be eligible to participate in the contest. Users have already been providing comments for apps that are currently available on Android Market, so it wouldn't make sense for them to "judge" the same apps again in this contest. In addition, apps that include or that are based on open source projects are fully welcomed, as long as the application itself is not on Android Market until August 1, 2009.
If you want to find out more details about ADC 2, you can find everything at the ADC 2 page along with the Terms and Conditions. For the moment, the most important thing to know is that ADC 2 submissions will be due August 31. I can't wait to see what you all come up with this time.
Happy coding -- and good luck!
