Android Studio 0.4.6 发布，主要更新内容如下：
Bug fixes. This is primarily a bug fix release from Android Studio 0.4.5 released five days ago. In particular, the Gradle sync editor notifications should be fixed now, as well as issues around switching language levels.
Source and documentation attachments. If you have plain Java library dependencies (for example on Guava or Joda-time), the Gradle sync will now automatically discover the associated source code and use those for the libraries, which makes javadoc popups work in code completion, which makes parameter documentation and suggested parameter names better, and so on. (Source attachments for AAR libraries is not yet working.)
Improvements to the project, activity and fragment templates:
The Blank Activity template no longer includes a fragment by default; there is a separate navigation type which will include it:
There is a new option to add Google+ login to the Login Activity template (New > Activity)
Similarly, there is a new "+1" fragment template.] (New > Android Component)
Some additional clipart is included in the Asset Studio wizard
