Google has released an unfinished SDK for the upcoming Honeycomb incarnation of Android, a release intended for touch tablets as well as smartphones.
According to Xavier Ducrohet, Google's Android SDK tech lead, Honeycomb is "specifically designed to give developers the tools and capabilities they need to create great applications for tablets and similar devices", and the "preview" SDK is a way for developers to test their applications on the new OS and get familiar with Google's new APIs and revamped user interface.
Honeycomb uses what Google insists on calling a "holographic" UI, and there's a new "interaction model" that involves stuff such as multitasking, notifications, and widgets. Google offers a short demo here:
In addition to a new UI framework, Google's preview SDK includes a new animation framework, hooks for multicore processors, additional Bluetooth APIs, and a set of enterprise-centric administrative policy tools. Alongside the SDK, Google has also released updates for Android's SDK Tools, Native Development Kit, and Android Development Tools (ADK) Plugin for Eclipse.
