Android's mobile operating system is based on the Linux kernel and is the world's best-selling Smartphone.

There are currently over 200,000 apps available for Android that are made accessible through the Android Market, which is the online app store run by Google.

The apps are primarily written in Java.

The Android operating system, including the Linux kernel, contains approximately 12 million lines of code.

In this there are: 3 million lines of XML, 2.8 million lines of C, 2.1 million lines of Java, and 1.75 million lines of C++.

Android Inc. was founded in Palo Alto, California in October, 2003 by Andy Rubin, Rich Miner, Nick Sears, and Chris White.

Their goal was to develop a "smarter mobile device that was more aware of its owner's location and preferences.”

They operated secretively, admitting only that they were working on software for mobile phones.

Google acquired Android Inc. in August, 2005, making Android Inc. a wholly owned part of Google Inc.

Nick Sears was the only original founder that did not stay with Android Inc. after the acquisition.

At this point in time, many assumed that Google was planning to enter the mobile phone market with this move.

Once at Google, Rubin led a team to develop a mobile device platform powered by the Linux kernel.

Google marketed the platform to handset makers and carriers with the intent of providing a flexible, upgradable system.

This caused speculation about Google's intention to enter the mobile communications market to build.

On October 21st, 2008, Android 1.0 became available to the public.

"Today's announcement is more ambitious than any single 'Google Phone' that the press has been speculating about over the past few weeks. Our vision is that the powerful platform we're unveiling will power thousands of different phone models.“ -Eric Schmidt, former Google Chairman/CEO

Android has support for multi-touch which was originally made available in handsets such as the HTC Hero.

The feature was originally disabled at the kernel level (possibly to avoid infringing Apple's patents on touch-screen technology at the time).

Google has since released an update for the Nexus One and the Motorola Droid which enables multi-touch.
