The update was originally thought to be a major one (rumors at the time referred to it as Android 5.0), and it seems like a quite a treat for Android users despite the minor version bump. So what has Google brought to the table this time around?
When Google announced Android 4.1 JellyBean, Dave Burke, Android engineering Director, talked about Project Butter.
In JellyBean this is the project to make the UI fast, fluid, and smooth.
First up on the list of additions to Jelly Bean is Project Butter, meant to make the Jelly Bean experience (naturally) “buttery smooth.” The Android team did so by bumping up Jelly Bean’s framerate to 60 FPS, and implemented vsync and triple buffering to tighten up the experience.
Developers also have access to a new tool called systrace in the Jelly Bean SDK that displays what the rendering engine is up to.
That all sounds great, but when can we get it? Google will begin their over-the-air updates to the Galaxy Nexus, Nexus S, and Motorola Xoom in the middle of July, and SDK is available today to developers looking to get their feet wet.
Google has added a new system trace tool aptly named systrace, which appears to show the time for each step taken in drawing a frame to the framebuffer. Systrace is now a part of the Android SDK as well.
