2. Introduction:
Android is a Linux-based mobile phone operating system
developed by Google. Android is unique because Google is
actively developing the platform but giving it away for free to
hardware manufacturers and phone carriers who want to use
Android on their devices.
Beyond the Phone:
A modified version of Android is used in the Google TV, the
Barnes & Noble Nook e-Reader, the Samsung Galaxy Tab, and
countless other devices. Parrot makes both a digital photo
frame and a car stereo system powered by modified versions
of Android.

3. What is Android?
Android is a Linux-based operating system for mobile devices such as smart phones
and tablet computers, developed by Google in conjunction with the Open Handset
Alliance. Android was initially developed by Android Inc, whom Google financially
backed and later purchased in 2005. The unveiling of the Android distribution in
2007 was announced with the founding of the Open Handset Alliance, a consortium of
86 hardware, software, and telecommunication companies devoted to advancing
open standards for mobile devices. Google releases the Android code as open-source,
under the Apache License. The Android Open Source Project (AOSP) is tasked with the
maintenance and further development of Android.
Android has a large community of developers writing applications ("apps") that
extend the functionality of the devices. Developers write primarily in a customized
version of Java, and apps can be downloaded from online stores such as Google Play
(formerly Android Market), the app store run by Google, or third-party sites. In June
2012, there were more than 600,000 apps available for Android, and the estimated
number of applications downloaded from Google Play was 20 billion.
Android became the world’s leading Smartphone platform at the end of 2010. For the
first quarter of 2012, Android had a 59% Smartphone market share worldwide. At the
half of 2012, there were 400 million devices activated and 1 million activations per
day.

4. Foundation:
Android, Inc. was founded in Palo Alto, California, United States
in October 2003 by Andy Rubin (co-founder of Danger),Rich
Miner (co-founder of Wildfire Communications, Inc.),Nick Sears
(once VP at T-Mobile),and Chris White (headed design and
interface development at WebTV) to develop, in Rubin's words
"...smarter mobile devices that are more aware of its owner's
location and preferences". Despite the obvious past
accomplishments of the founders and early employees, Android
Inc. operated secretly, revealing only that it was working on
software for mobile phones. That same year, Rubin ran out of
money. Steve Perlman, a close friend of Rubin, brought him
$10,000 in cash in an envelope and refused a stake in the
company.

5. Google acquisition:
Google acquired Android Inc. on August 17, 2005, making Android Inc. a
wholly owned subsidiary of Google. Key employees of Android
Inc., including Andy Rubin, Rich Miner and Chris White, stayed at the
company after the acquisition. Not much was known about Android Inc. at
the time of the acquisition, but many assumed that Google was planning to
enter the mobile phone market with this move.
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, upgradable
system. Google had lined up a series of hardware component and software
partners and signaled to carriers that it was open to various degrees of
cooperation on their part.

6. Speculation about Google's intention to enter the mobile
communications market continued to build through
December 2006. Reports from the BBC and The Wall
Street Journal noted that Google wanted its search and
applications on mobile phones and it was working hard
to deliver that. Print and online media outlets soon
reported rumors that Google was developing a Google-
branded handset. Some speculated that as Google was
defining technical specifications, it was showing
prototypes to cell phone manufacturers and network
operators.
In September 2007, InformationWeek covered an
Evalueserve study reporting that Google had filed several
patent applications in the area of mobile telephony.

7. Android Open Source Project:
The Android Open Source Project (AOSP) is led by Google, and is
tasked with the maintenance and development of Android. According
to the project "The goal of the Android Open Source Project is to
create a successful real-world product that improves the mobile
experience for end users.” AOSP also maintains the Android
Compatibility Program, defining an "Android compatible" device "as
one that can run any application written by third-party developers
using the Android SDK and NDK", to prevent incompatible Android
implementations. The compatibility program is also optional and free
of charge, with the Compatibility Test Suite also free and open-source

8. Open Handset Alliance:
On November 5, 2007, the Open Handset Alliance, a
consortium of several companies which include Broadcom
Corporation, Google, HTC, Intel, LG, Marvell Technology
Group, Motorola, Nvidia, Qualcomm, Samsung Electronics, Sprint
Nextel, T-Mobile and Texas Instruments unveiled itself. The goal of
the Open Handset Alliance is to develop open standards for mobile
devices. On the same day, the Open Handset Alliance also unveiled
its first product, Android, a mobile device platform built on the
Linux kernel version 2.6.
On December 9, 2008, 14 new members
joined, including ARM Holdings, Atheros Communications, Asustek
Computer Inc, Garmin Ltd, Huawei
Technologies, PacketVideo, Softbank, Sony Ericsson, Toshiba
Corp, and Vodafone Group Plc.
