3. Introduction

4. Android is a mobile operating system developed by Google,
based on a modified version of the Linux kernel and other open
source software and designed primarily for touchscreen mobile
devices such as smartphones and tablets. In addition, Google
has further developed Android TV for televisions, Android
Auto for cars, and Wear OS for wrist watches, each with a
specialized user interface. [1]

5. History

6. Android Inc. was founded in October 2003 by Andy Rubin, Rich
Miner, Nick Sears, and Chris White. The intentions of the company
is to develop an advanced operating system for digital cameras. The
company then decided that the market for cameras was not large
enough for its goals, and by five months later it had diverted its
efforts and was pitching Android as a handset operating system that
would rival Symbian and Microsoft Windows Mobile.

8. In July 2005, Google acquired Android Inc. for at least $50 million. Its key
employees, including Rubin, Miner and White, joined Google. At Google,
the team led by Rubin developed a mobile device platform powered by
the Linux kernel. Google marketed the platform to handset
makers and carriers on the promise of providing a flexible, upgradeable
system.

9. Google's intention was to enter the mobile communications market continued to
build through December 2006. But the arrival of 2007's Apple iPhone with
Touchscreen Displays meant that Android "had to go back to the drawing
board". Google later changed its Android specification that "Touchscreens will
be supported", although "the Product was designed with the presence of discrete
physical buttons as an assumption, therefore a touchscreen cannot completely
replace physical buttons". By 2008, both Nokia and BlackBerry announced
touch-based smartphones to rival the iPhone 3G, and Android's focus eventually
switched to just touchscreens. The first commercially available smartphone
running Android was the HTC Dream announced on September 23, 2008.

10. Android has been the best-selling OS worldwide on
smartphones since 2011 and on tablets since 2013. As of
May 2017, it has over two billion monthly active users, the
largest installed base of any operating system, and as of
June 2018, the Google Play store features over 3.3 million
apps.

11. Android Versions

each Android version is named after a dessert"
