Some of those desserts may have been abandoned codenames. Sometimes you'll see a flan--not sure if that's what Froyo was called at first. And, of course, you may also see a key lime pie, which became KitKat. But on that screenshot, I can see Cupcake, Donut, Eclair, Froyo, Gingerbread, Honeycomb, Ice Cream Sandwich, Jellybean, and KitKat. Not sure why they throw a basic Android logo in there as well. The one that looks like a stacked diamond I think is a petit four, but I have no idea why that's there.
