Android Studio 2.4 Preview 1 发布
Android Studio 2.4 Preview 1 发布了，这是一个早期的构建版本，所以在未来几周会有更多的更新。
Incremental dex’ing. Dex’ing is now done at a per class level. This allows for more incrementality and will result in faster incremental builds. You should also expect improved build speeds for applications using legacy multi-dex (minSdkVersion < 21).
Dependency resolution at execution time. In previous versions, dependency resolution occurs during Gradle configuration time. By moving dependency resolution to execution time, you should expect improved configuration times for large projects.
