Android 4.1 Jelly Beans New features detailed

The conference is over, Android's new generation of 4.1, code-named Jelly Bean (jelly beans) of the system has been officially published, in addition to the new architecture, new notice bar and search function, in fact, the new system has many new features, in the press conference can not complete the display, Now we have to analyze these new features, so that you see 4.1 version of the system will not be worth looking forward to. 1. Faster, smoother and more sensitive in the speech, in addition to hear the word jelly beans, there is a project Butter, this is the new system's most important enhancement project. First of all, the new system uses a newer processing architecture, the support for multi-core processors is finally coming, the dual-core and quad-core processors appearing in Android devices will be better tuned to perform strong performance. Second, in the new system, the frame speed of special effects animation to 60fps,4.1 version of the system will also optimize the best performance and very low touch latency, provide a smooth, intuitive user interface. To ensure consistent frame speed, all graphics and animations in the 4.1 version of the Android framework will be unified vsync timing, application rendering, touch events, picture composition, display refresh operations will be locked in 16 millisecond response, all frames are not advanced or backward. Android 4.1 also adds three times buffers to make the rendering feel smoother. The touch delay not only follows the VSync timing, but also makes advance rendering prior to the touch operation, in addition to allocating more processing power when the CPU is idle to handle the touch events to ensure that the touch is not delayed. The SDK development tool will also provide a new tool systrace that allows developers to determine the cause of the rendering disruption by directly mobile data from the Linux kernel.
