Just a couple quick tidbits from the I/O keynote in case you missed them: Google will be publishing factory image previews of the "L" release of Android for the Nexus 5 and Nexus 7 (presumably 2013 only) tomorrow morning, that being June 26th. We're guessing anyone can download them, so long as you're comfortable flashing an image to your device.
You can see a few more features and APIs in the L here.
The preview SDK for "L" should be going up today, too, and that SDK includes more than 5,000 new APIs, a truly massive number. Three of the big ones Google teased are Bluetooth 4.1, USB audio, and burst photo mode (so third party apps can now take burst shots). Pretty neat stuff. Now, get back to a more exciting post - there's a lot going on today!
