  • 3. What is Android?Android is a Linux-based operating system for mobile devices such as smart phonesand tablet computers, developed by Google in conjunction with the Open HandsetAlliance. Android was initially developed by Android Inc, whom Google financiallybacked and later purchased in 2005. The unveiling of the Android distribution in2007 was announced with the founding of the Open Handset Alliance, a consortium of86 hardware, software, and telecommunication companies devoted to advancingopen 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 themaintenance and further development of Android.Android has a large community of developers writing applications ("apps") thatextend the functionality of the devices. Developers write primarily in a customizedversion 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 June2012, there were more than 600,000 apps available for Android, and the estimatednumber of applications downloaded from Google Play was 20 billion.Android became the world’s leading Smartphone platform at the end of 2010. For thefirst quarter of 2012, Android had a 59% Smartphone market share worldwide. At thehalf of 2012, there were 400 million devices activated and 1 million activations perday.

Foundation:Android, Inc. was founded in Palo Alto, California, United Statesin October 2003 by Andy Rubin (co-founder of Danger),RichMiner (co-founder of Wildfire Communications, Inc.),Nick Sears(once VP at T-Mobile),and Chris White (headed design andinterface development at WebTV) to develop, in Rubins words"...smarter mobile devices that are more aware of its ownerslocation and preferences". Despite the obvious pastaccomplishments of the founders and early employees, AndroidInc. operated secretly, revealing only that it was working onsoftware for mobile phones. That same year, Rubin ran out ofmoney. Steve Perlman, a close friend of Rubin, brought him$10,000 in cash in an envelope and refused a stake in thecompany.
  • 5. Google acquisition:Google acquired Android Inc. on August 17, 2005, making Android Inc. awholly owned subsidiary of Google. Key employees of AndroidInc., including Andy Rubin, Rich Miner and Chris White, stayed at thecompany after the acquisition. Not much was known about Android Inc. atthe time of the acquisition, but many assumed that Google was planning toenter the mobile phone market with this move.At Google, the team led by Rubin developed a mobile device platformpowered by the Linux kernel. Google marketed the platform to handsetmakers and carriers on the promise of providing a flexible, upgradablesystem. Google had lined up a series of hardware component and softwarepartners and signaled to carriers that it was open to various degrees ofcooperation on their part.

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 anEvalueserve study reporting that Google had filed several patent applications in the area of mobile telephony.
