The Android 4.1 SDK has been released to the Android Developer Network as well.

Android 4.1 also adds triple buffering in the graphics pipeline, for more consistent rendering that makes everything feel smoother, from scrolling to paging and animations.

Android 4.1 reduces touch latency not only by synchronizing touch to vsync timing, but also by actually anticipating where your finger will be at the time of the screen refresh. This results in a more reactive and uniform touch response. In addition, after periods of inactivity, Android applies a CPU input boost at the next touch event, to make sure there’s no latency.

But with this quick update of Android operating system when most devices are still waiting for an upgrade to an older operating system will add to the Android fragmentation which has been plaguing the system for long time. And its for sure that this is going to add to the agony of the developers who have to support so many devices with different operating systems at the same time.
