We’ve just scheduled Android Developer Labs for Melbourne (January 31), Sydney (February 3), and Auckland (February 8). The material is not introductory; it’s aimed at people with existing apps who want to make them better in the era of Ice Cream Sandwich and tablets. You’ll want to show up with the SDK installed, and a couple of devices.
If this describes you, drop by the ADL page and sign up. You should hurry, because these are not large-scale events and there are more qualified people than there are seats.
