我们很高兴的通知 Android 3.0 完整的 SDK 已经可以下载（需翻墙），这是最终版的，你现在可以用它来开发 Android 3.0 平台的应用了，新的 API 级别是 11 。
关于 Android 3.0 的用户和开发详情请看：Android 3.0 Platform Highlights.
同时我们也将计划更新 SDK Tools (r11) 和 ADT 插件(10.0.0)，主要改进包括：
- UI Builder improvements in the ADT Plugin:
- New Palette with categories and rendering previews. (details)
- More accurate rendering of layouts to more faithfully reflect how the layout will look on devices, including rendering status and title bars to more accurately reflect screen space actually available to applications.
- Selection-sensitive action bars to manipulate View properties.
- Zoom improvements (fit to view, persistent scale, keyboard access) (details).
- Improved support for <merge> layouts, as well as layouts with gesture overlays.
- Traceview integration for easier profiling from ADT. (details)
- Tools for using the Renderscript graphics engine: the SDK tools now compiles .rs files into Java Programming Language files and native bytecode.
