Android (/æn.drɔɪd/; AN-droyd) is a Linux-based operating system designed for touch screen mobile devices such as smart phones and tablet computers. Android was originally developed by Android, Inc., with financial support from Google, which then bought it in 2005.
The operating system was officially released in 2007, in conjunction with the establishment of the Open Handset Alliance, a consortium of hardware, software and telecommunications companies aimed at advancing mobile open standards. The first Android phone went on sale in October 2008.
The Android user interface is generally a direct manipulation, using touch gestures similar to real actions, such as shifting, tapping, and pinching to manipulate objects on the screen, as well as a virtual keyboard to write text.
In addition to touch screen devices, Google has also developed Android TV for television, Android Auto for cars, and Android Wear for watches, each with a different user interface. Android variants are also used on portable computers, game consoles, digital cameras, and other electronic equipment.
Android is an open source operating system, and Google is releasing its code under the Apache License. Open source code and licensing licenses on Android allow software to be freely modified and distributed by device makers, wireless carriers and app developers. In addition, Android has a large number of application developer communities (apps) that extend device functionality, commonly written in the customized version of the Java programming language.
In October 2013, there are over a million apps available for Android, and about 50 billion apps have been downloaded from Google Play, the main Android app store. A survey in April-May 2013 found that Android is the most popular platform for developers, used by 71% of mobile app developers. In Google I / O 2014, Google reports that there are more than one billion monthly active Android users, up from 583 million in June 2013.
The factors above have contributed to the development of Android, making it the most widely used smartphone operating system in the world and beat Symbian in 2010. Android is also an option for technology companies that want low-cost, customizable, and lightweight operating systems for high-tech devices without having to develop from scratch.
The open nature of Android has also encouraged the emergence of a large number of app developer communities to use open source code as the basis for app-making projects, by adding new features to advanced users or operating Android on devices officially released using other operating systems.
In November 2013, Android dominated the global smartphone market, led by Samsung products, with a percentage of 64% in March 2013. In July 2013, there were 11,868 different Android devices with different versions. The success of this operating system also makes it a target of patent litigation "smart phone war" between technology companies.

Until May 2013, a total of 900 million Android devices have been activated worldwide, and 48 billion apps have been installed from Google Play.
