摘要(Abstract)
ndroid是一种基于Linux的自由及开放源代码的操作系统。主要使用于移动设备，如智能手机和平板电脑，由Google（谷歌）公司和开放手机联盟领导及开发。尚未有统一中文名称，中国大陆地区较多人使用“安卓”或“安致”。Android操作系统最初由Andy Rubin开发，主要支持手机。2005年8月由Google收购注资。2007年11月，Google与84家硬件制造商、软件开发商及电信营运商组建开放手机联盟共同研发改良Android系统。随后Google以Apache开源许可证的授权方式，发布了Android的源代码。第一部Android智能手机发布于2008年10月。Android逐渐扩展到平板电脑及其他领域上，如电视、数码相机、游戏机、智能手表等。2011年第一季度，Android在全球的市场份额首次超过塞班系统，跃居全球第一。 2013年的第四季度，Android平台手机的全球市场份额已经达到78.1%。 [1] 2013年09月24日谷歌开发的操作系统Android在迎来了5岁生日，全世界采用这款系统的设备数量已经达到10亿台。中文名 安卓 原版名称 Android 开发商 Google、开放手持设备联盟 发行商 Google 发行日期 2008年9月23日 制作人 安迪·鲁宾 最新版本Android 9.0 Pie（派） 最新预览版本 Android Q Beta1 发行阶段 正式版 编程语言C/C++（底层） Java等（应用层） 系统家族类Unix,Linux 源码模式 自由及开放源代码软件 内核类型宏内核(Linux内核) 软件许可 Apache License、 GPL等
