Google’s new Android Runtime (ART) technology is doubling the app performance over Dalvik, which is what is used today. The next “L” version of Android uses a new software foundation that doubles software performance said Google at the I/O conference.
ART will replace Dalvik, which runs apps written for Android smartphones and tablets. ART roughly doubles the performance of Android apps. Developers do not have to make a change, the app code gets the performance for free.
Google launched a prototype of ART in 2013 with the release of Android 4.4 KitKat, but it was not activated by default due to compatibility issues. ART has shorter pauses for memory-scrubbing garbage collection, according to CNET.
ART supports the 64-bit ARMv8 architecture, the 64-bit x86-64 architecture from Intel and Advanced Micro Devices, and the MIPS64 architecture from MIPS. ART and Dalvik are virtual machines, which are software layers that runs application software.
