Android Jelly Bean

Android 4.1 JellyBean:

Jelly Bean came out in 2012. Biggest changes included"Google Now", an AI assistant antipates your needs and better, more intractive notifications. Jelly Bean also allows "voice typing", a built-in speech-to-text engine that does not rely on Internet or data.

For jelly bean , work was made on optimizing the operating system's visual performance and responsiveness through a series of changes reffered to as "project butter". graphical output is now triple buffered, vsync is used across all drawing operations, and the CPU is brought to full power when touch input is detected preventing the lag associated with inputs made while the processor is in a low power stste. these changes allow the operating system to run at a full 60 frames per second on capable hardware.
Following 4.1. two more Android releases were made under the Jelly Bean codename; both of these releases focused primarily on performance improvements and changes to Android platform itself, and contained relatively few user facing changes. Along Android 4.1, Google also began to decouple APLs for its services on ANdroid into a new system level component known as Google Play services , served through Google Play Store. This allows the addition of certain forms of functionality without having to distribute an upgrade to the operating system itself addressing the infamous "fragmentation" problems experienced by the Android ecosystem.
