Android : Android "Handler" class missing in Intellij IDEA 13.1.4

I've recently moved from Eclipse + ADT to IntelliJ IDEA. My current project is using:

Gradle 2.1

JDK 1.7.0_67

MinSdk 15

TargetSdk 19

When I attempt to import the Android "Handler" class, it is simply not there.

The only "Handler" I see there is the "java.util.logging" class, which is not what I need.

I have triple checked my project structure and that the appropriate API (19) is set as the project and module API level.

I'm obviously missing something here and any help would be greatly appreciated.

Thanks in advance!
