Introduction to Android operating system

Andy Rubin has created two mobile operating system companies: Danger and Android. Danger 500 million dollars to Microsoft, this year became KIN,ANDROID4 tens of millions of dollars sold to Google. Android is the name of the Linux platform based open source mobile operating system, announced on November 05, 2007 by Google, which consists of operating systems, middleware, user interfaces, and application software. It uses the Software heap layer (Software stack, also known as software Overlay) architecture, mainly divided into three parts. The bottom layer is based on Linux kernel work, developed by C language, only provides basic function, middle tier includes library library and virtual machine Machine, developed by C + +. The top layer is a variety of applications, including call procedures, SMS programs, and so on, the application software by the company's own development, in Java as part of the writing program. There are no proprietary barriers that have previously hindered the innovation of the mobile industry, claiming to be the first truly open and complete mobile software to be built for mobile terminals.

Android Google, through a deep partnership with software, hardware developers, equipment manufacturers, telecom operators and others, hopes to build an open ecosystem in the mobile industry with the help of a standardized, open mobile phone software platform.

Android, as an important part of Google's corporate strategy, will further advance the corporate goal of "providing everyone with information anytime, anywhere." Many mobile phone users around the world are using a variety of phones based on Android. Google's goal is to make (mobile communications) independent of devices and even platforms. For this purpose, Android will complement, rather than replace, Google's long-standing mobile development strategy: to develop both attractive and mobile services and to promote them by partnering with handset manufacturers and mobile operators around the world.
