Android Studio 0.8.1(Beta)支持Android L

New intention action to override resources

Automatic platform component downloading during Gradle sync when a required platform is missing. For example, if your build.gradle file requires API 19, but your SDK install does not have Android 4.4 installed, you will get a fix link in the Gradle Sync window which offers to install it:

When you click on it, you'll first get a license agreement dialog, and then it will continue to install the missing component and restart the sync. 

This is not specific to missing Android SDK versions; it will also install missing build tools versions, or missing Android or Google Maven repositories.

Gradle Sync Caching. We now cache the synced Gradle model across IDE invocations, so if you exit the IDE and restart, the IDE should be ready to use much more quickly.
