                                           Android, a mobile operating system is developed by google and based on the Linux kernel. Android has a user interface based on direct manipulation, which makes it’s primary design touchscreen. Some of the touchscreen devices are smartphones and tablet computers. For other devices like android televisions, android auto cars and android wear, the user interfaces are specialized. Android uses touch inputs, with a virtual keyboard, tapping, swiping, pinching and reverse pinching are some of the actions used to manipulate on screen objects.


Android is a very widely used operating system. From July 2013, the google play store had over one million Android applications published and over 50 billion applications downloaded.

The operating system’s success has made it a target for patent litigation as part of the so-called “smartphone wars” between technology companies
