The next major version of Android, which will probably be unveiled at Google I/O next week, will remove the Dalvik runtime and replace it with ART -- the new Android Runtime. The main purpose of ART is to improve performance and smoothness of both third-party Android apps and the core apps and interface. Brian Carlstrom, a member of Google's Dalvik engineering team, announced the Dalvik-ART switch-over with this rather amusing patch note: 'Dalvik is dead, long live Dalvik! DO NOT MERGE.'
