Google Announces Android 4.1 Jelly Bean and Project Butterby Brian Klug on June 27, 2012 1:49 PM EST
Back at Mobile World Congress, both Anand and I heard rumblings that UI performance would be a huge emphasis in the next major release of Android. I remember being told that the goal would be to make performance smooth as butter, everywhere. Today, Google has made that official with Android 4.1 Jelly Bean, and Project Butter.
There are a number of improvements we're going to be going over in detail soon, but probably the most visible to end users will be those improvements to UI performance with butter. Google mentioned three key things - changes to Vsync, triple buffering (which was not enabled for the OpenGL ES UI render path in the past), and improvements to the CPU governor. The end result is that the SoC will change perf states based on touch input to dramatically increase touch responsiveness.
