Android(安卓)是移动和便携设备中应用最广的操作系统。笔者从一个Android应用开发者的角度,简要介绍了Android系统的来源及主要优点,详细说明了其进程管理机制特别是进程优先级与进程分类和进程回收机制之间的关系,提出了进程保护概念,并归纳了常用的进程保护方法,提出了一种行之有效的进程保护方案,并详细分析、解读了该方案的原理、实现方法以及核心源代码。

Android is the most widely used operating system in mobile and portable devices.From the perspective of an Android application developer,the author briefly introduces the origin and main advantages of Android system,explains in detail the relationship between its process management mechanism,especially the process priority,process classification and process recovery mechanism,puts forward the concept of process protection,summarizes commonly used process protection methods,and proposes an effective process protection scheme.The principle,implementation method and core source code of the scheme are analyzed and interpreted in detail.
