Google's Android 3.0 Honeycomb gets SDK update and first public preview
Important new features include a collection of new themes, widgets, notifications and other UI elements designed for the larger-screen devices Honeycomb is meant to run on. You'll also find improvements to 2D and 3D graphics and animation, and support for multicore processors. Less thrilling, but still important, are new Bluetooth APIs, enterprise encryption and password features, and a new DRM framework.
This update doesn't contain the final APIs, but it's close enough to the final system image that developers can use it to start testing their apps and playing with the new UI. Check out Engadget's hands on video with a build of the preview release after the break.
