What is Android Operating System?

Android is the world's most popular mobile operating system (OS). With Android you can use all the Google apps you know and love, plus there are more than 700,000 apps and games available on Google Play to keep you entertained, alongside millions of songs and books, and thousands of movies. Android devices are already smart, and will only get smarter, with new features you won't find on any other platform, letting you focus on what's important and putting you in control of your mobile experience.

Android is a Linux-based OS designed primarily for touchscreen mobile devices such as smartphones and tablet computers.

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.
