oh hey, I stopped the android thing when I started making that contest project and I realized I could make a truly high quality pc project, but I believe what I was doing was using the larger images only, and then shrinking it to screensize , designing it for Motorola Droid screen, and allowing the other phones to widen or shorten the sides (it was a landscape game). they have that special resolution independent pixel, that's the same size on any screen, but I wasn't using that because I hadn't gotten to the UI yet, and I'd rather the game characters be tiny on small screens, than have the player have less play space
if you need more specifics I'll fire up eclipse and see if I can find the old files
also, if you have any trouble with specifics, like getting accelerometer, or touch values, or simulating imagepoints, and I do find my eclipse files, I'll be happy to help with any questions.
it's been a month or so though, so I'm a little rusty
