Jelly Bean function Decryption: Butter plan improve fluency

Another important enhancement of the Jelly bean is called the Butter Plan (Project Butter). Like its name, butter plans to make the operating system run faster with a new, more efficient framework that supports up to 60fps of animation. Android 4.1 also makes applications more responsive and can be used to get your fingers to touch them when the screen is refreshed. Butter Program (Project Butter) So how does this improvement work? Let's take a look at the message from the Android Developer website: To ensure consistent frames, Android 4.1 The system framework for rendering and animation will be in the form of vertical synchronization (VSync). Everything follows a 16-millisecond cycle, including applied rendering, touch action, picture composition and realistic refresh, and so on, so there will not be any frame number ahead or behind. Android 4.1 also adds triple buffering to the graphics pipeline, making scrolling and flipping more consistent and smoother. Android 4.1 is not just a vertical sync to reduce the latency of touch response, but also to advance your finger's next touch position when the screen is refreshed. This makes the touch operation more sensitive and consistent. In addition, during idle time, the Android system will allow the CPU input to boost when the next touch occurs to ensure there is no delay. The vertical sync (vsync) butter Project (Project Butter) brings us a major improvement in the Android system, and Google is finally starting to deal with the age-old and important issue of Android's fluency.
