At the Google I/O conference a month ago, we demonstrated the next version of the Android Development Tools (ADT) plugin. Today we’re happy to announce that version 11 is done and available for download!

ADT 11 focuses on editor improvements. First, it offers several new visual refactoring operations, such as “Extract Include” and “Extract Style,” which help automatically extract duplicated layout fragments and style attributes into reusable layouts, styles, and themes.

Second, the visual layout editor now supports fragments, palette configurations, and improved support for custom views.

Last, XML editing has been improved with new quick fixes, code completion in more file types and many “go to declaration” enhancements.

ADT 11 packs a long list of new features and enhancements. Please visit our ADT page for more details. For an in-depth demo, check out the video of our Android Development Tools session at Google I/O, below.

Please note that the visual layout editor depends on a layout rendering library that ships with each version of the platform component in the SDK. We are currently working on a number of improvements to this library as well, which we plan to release soon for all platform versions. When we release the updates, some new features in ADT 11 will be “unlocked” - such as support for ListView previewing - so keep an eye on this blog for further announcements.
