What is Android?

阅读更多

          Android(安卓)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。

          Android 不同,Android对所有人开放,而不只是一家厂商。你可以在摩托、三星、LG等几十个厂商的手机上运行Android。对于开发者来说,这一点意义重大,它意味着你写的手机应用可以无需修改地运行在几十个不同厂商出产的手机上。 

   

         Android的优点:

      1,Android是一个多任务操作系统,最近运行过的程序都常驻后台,而在内存管理上则由系统选择性的自动杀掉占用内存的近期非活跃进程

      2,运行速度也是Google手机 的强项之一,尽管其核心处理器的频率以及内存搭配并非最顶级的配置,但在Android平台中有着畅快淋漓的速度表现

     3.界面美观

   

         Android的缺点:

    1.碎片化严重

    2.容易崩溃和死机

    3 .安全和隐私:由于手机与互联网的紧密联系,个人隐私很难得到保守。除了上网过程中经意或不经意留下的个人足迹,Google这个巨人也时时站在你的身后,洞穿一切,因此,互联网的深入将会带来新一轮的隐私危机。

       

         Android开发的优点:

     1.系统自带大量封装好的控件,而且可以自定义控件

     2.系统携带大量的库函数.
