Hong Kong is the last location of Android Developer Lab World Tour, and I attended this event yesterday (March 5, 2010)

Just got this error from Mac version of Eclipse with Android SDK while compiling an android application.

To solve the problem, simply go to ./android and delete debug.keystore. The key will be expired automatically after one year of usage and you have to delete the old key so that new key will be created automatically.

I am using an iPhone application called AppSales that used to be an opensource project here:
http://code.google.com/appsales-mobile/
that tracks my iPhone apps revenue from my iPhone. But since last few days (28 July 2009), I could not get the data from iTune anymore. Then I found that the webpage that for accessing the data is changed. I checked google code for an update. Surprisingly the AppSales project cannot be accessible anymore. I hope it is only an error in google code.
