auxiliary information: Android is a mobile operating system based on the Linux kernel and currently developed by Google. With a user interface based on direct manipulation, Android is designed primarily for touchscreen mobile devices such as smartphones and tablet computers, with specialized user interfaces for televisions, cars, and wrist watches. The OS uses touch inputs that loosely correspond to real-world actions, like swiping, tapping, pinching, and reverse pinching to manipulate on-screen objects, and a virtual keyboard. Despite being primarily designed for touchscreen input, it has also been used in game consoles, digital cameras, regular PCs, and other electronics. As of 2015, Android has the largest installed base of all operating systems. As of July 2013, the Google Play store has had over one million Android applications published, and over 50 billion applications downloaded. An April‚ÄìMay 2013 survey of mobile application developers found that 71% of them create applications for Android; another 2015 survey found that 40% of full-time professional developers see Android as the "priority" target platform, which is more than iOS or other platforms.
