Google Introduces New “ART” Android Runtime for KitKat 4.4 OS

Google has introduced “ART,” a new Android runtime being introduced experimentally for the recent KitKat 4.4 release. It is a preview of a work in progress in KitKat that can be turned on in Settings > developer options. Google says the release has been made to obtain early developer and partner feedback.

ART has been developed as an alternative to “Dalvik,” which is the virtual process machine that makes it possible to run apps on Android. Google emphasizes that Dalvik must remain the default runtime or developers risk breaking their Android implementations and third-party applications.
