That didn't take long at all. Probably the complete opposite, actually. But, while Google I/O is still going strong, and we're covering everything that slips out of the conference, Google and the Android Team have officially made the Android 2.2 Software Developer's Kit (SDK) available for download.
Which, if you're into that kind of thing, means you can head on over to the Android site, find what you're looking for, and start up the download and get to that whole developing thing. The initial download is only 18 megabytes, so not bad at all. You'll get some tools, that don't tell you any specific platforms at the moment. But, then you pull from another application that you can tell which platform you want, which means you can still develop for Android 1.5.
We know there's a few developers out there, so go ahead and take a grab at it, and let us know what you think! Of course, if you're working on anything in particular, by all means, let us know!
