Introduction
Android
is a Linux-based operating
system designed primarily for touchscreen mobile devices such as smartphones and tablet
computers. Initially developed by Android, Inc., which Google backed financially
and later bought in 2005,Android was unveiled in 2007 along with the founding of the Open Handset
Alliance: a consortium of hardware, software, and telecommunication companies devoted to
advancing open
standards for mobile devices.
The first Android-powered phone was sold in October 2008.
Android
is open source
and Google releases the code under the Apache License.
This open source code and permissive licensing allows the software to be freely
modified and distributed by device manufacturers, wireless carriers and
enthusiast developers. Additionally, Android has a large community of
developers writing applications ("apps") that extend the functionality of
devices, written primarily in a customized version of the Java programming language.In October 2012, there were approximately 700,000 apps available for Android,
and the estimated number of applications downloaded from Google Play, Android's
primary app store, was 25 billion.
