The automatic AVD creation feature is great, but it will only work for a single Android project. Since the AVDs are named based on the characteristics (screen res, etc.) it is likely that two different Android projects will collide on the same AVD. This could be quite problematic when either (or both) projects have the "Reset emulator state at start-up" setting enabled. I believe this should be easily overcome by adding a Hudson project name element to the AVD name.
