摘要
Android操作系统目前已经广泛运用于各种移动设备。Android显示系统架构是Android的核心架构之一,在开发和测试过程中发现,Android 2.3上时常有界面冻结的情况出现,而在Android 4.0版本上,这种情况却很少出现。基于Android 4.0,通过对其显示系统核心SurfaceFlinger代码进行深入分析研究,找到了其改进点,相应地得出了Android 2.3 SurfaceFlinger现有设计所必然会导致的屏幕冻结的问题所在。
Android operating system has been widely used in a variety of mobile devices, Android display system architecture is one of the core architectures of Android, it is found in developing and testing process that Android 2.3 UI often frozen in running, but in Android 4.0 version, this situation rarely happens. Based on Android 4.0, through in-depth analysis and study on its display system core SurfaceFlinger code, we find out the points of improvement, and correspondingly discover the root of the frozen screen problem which is inevitably caused by the existing Android 2.3 SurfaceFlinger design.
