With Android Lollipop deployment is upon us, we at mytechgarbage will take a look at what would be the most significant change under the hood, ART. ART or Android Run Time is the new Runtime system used by Android Lollipop to replace the Dalvik that was used since the creation of Android. To anyone with Developer option enabled on their KitKat Android, ART is not new as it was an option earlier where user can toggle between Dalvik and ART. In Lollipop, there is no option to disable ART as it is the only available Runtime.
What will ART bring?
Since the early incarnation of Android, Dalvik is the one and only way to run apps on Android. Dalvik is essentially a Virtual Machine system and would be great on limited resources device. Dalvik has went through multiple upgrades such as JIT in version 2.2, but it is still not efficient enough to use the current available extra CPU and Memory. ART in the other hand, would be able to utilized the extra CPU core and memory available and bring Android to the 64bit age.
