摘要

Android一词的本义指“机器人”，同时也是Google于2007年11月5日宣布的基于Linux 平台的开源手机操作系统的名称，该平台由操作系统、中间件、用户界面和应用软件组成，号称是首个为移动终端打造的真正开放和完整的移动软件。目前，最新版本为Android 4.0 Ice Cream Sandwich。

Android早期由原名为"Android"的公司开发，谷歌在2005年收购"Android.Inc"后，继续对Android系统开发运营，它采用了软件堆层（software stack，又名软件叠层）的架构，主要分为三部分。底层以Linux内核工作为基础，由C语言开发，只提供基本功能；中间层包括函数库Library和虚拟机Virtual Machine，由C++开发。最上层是各种应用软件，包括通话程序，短信程序等，应用软件则由各公司自行开发，以Java作为编写程序的一部分。Android 作为Google企业战略的重要组成部分，将进一步推进“随时随地为每个人提供信息”这一企业目标的实现。全球为数众多的移动电话用户正在使用各种基于Android 的电话。谷歌的目标是让（移动通讯）不依赖于设备甚至平台。出于这个目的，Android 将补充，而不会替代谷歌长期以来奉行的移动发展战略：通过与全球各地的手机制造商和移动运营商结成合作伙伴，开发既有用又有吸引力的移动服务，并推广这些产品。

2011年初数据显示，仅正式上市两年的操作系统Android已经超越称霸十年的塞班系统，使之跃居全球最受欢迎的智能手机平台。Android的主要竞争对手是苹果公司的iOS以及RIM 的Blackberry OS[2]。
