Android Workshop

Android is a Linux based operating system for mobile devices such as smartphones and tablet computers. It is developed by the Open Handset Alliance led by Google.[9][10]

Google purchased the initial developer of the software, Android Inc., in 2005.[11] The unveiling of the Android distribution in 2007 was announced with the founding of the Open Handset Alliance, a consortium of 84 hardware, software, and telecommunication companies devoted to advancing open standardsfor mobile devices.[12][13][14][15] Google releases the Android code as open-source, under the Apache License.[16] The Android Open Source Project (AOSP) is tasked with the maintenance and further development of Android.[17]

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.[18] As of October 2011 there were more than 400,000 apps available for Android, and the estimated number of applications downloaded from the Android Market as of December 2011 exceeded 10 billion.[19][20] Apps can be downloaded from third-party sites or through online stores such as Android Market, the app store run by Google.

Android was listed as the best-selling smartphone platform worldwide in Q4 2010 by Canalys[21][22] with over 200 million Android devices in use by November 2011.[23] According to Google's Andy Rubin, as of December 2011 there are over 700,000 Android devices activated every day.[24]
