Google introduced Android Jelly Bean on Google I/O 2012 in San Francisco.
Boasting a new Google search experience on Android, Project butter is the marquee addition to Android 4.1 Jelly Bean. Based on Linux kernel 3.0.31 and API level 16, Jelly Bean was an update with the primary aim of improving the functionality and performance of the user interface. The performance improvement involving the Project Butter uses touch anticipation, triple buffering, extended Vsync timing and a fixed frame rate of 60 fps to create a fluid and "buttery-smooth" UI.
