What is Android:
Android is a mobile operating system (OS) based on the Linux kernel
and currently developed by Google.

mobile devices such as smartphones and tablet computers, with specialized user interfaces for televisions (Android TV),
cars (Android Auto), and wrist watches (Android Wear).
The touch inputs are - swiping, tapping, pinching, and reverse pinching to manipulate on-screen
objects, and a virtual keyboard. Android although designed for touchscreen, has also been used in game consoles, digital cameras,
regular PCs, and other electronics. As of 2015, Android has the largest
installed base of all operating systems.

An April–May 2013
survey of mobile application developers found that 71% of them create
applications for Android; another 2015 survey found that 40% of full-time professional
developers see Android as the "priority" target platform, which is
more than iOS

store has had over one million Android applications ("apps")
published, and over 50 billion applications downloaded.

code name
and released in alphabetical order, beginning with Android 1.5
"Cupcake"; the earlier versions 1.0 and 1.1 were not released under
