short notice about Android

Android is a mobile operating system developed by Google, based on the
Linux kernel and designed primarily for
touchscreen mobile devices such as
smartphones and tablets . Android's user interface is mainly based on direct manipulation, using touch gestures that loosely correspond to real-world actions, such as swiping, tapping and pinching, to manipulate on-screen objects, along with a virtual keyboard for text input. In addition to touchscreen devices, Google has further developed
Android TV for televisions, Android Auto for cars, and Android Wear for wrist watches, each with a specialized user interface. Variants of Android are also used on game consoles, digital cameras , PCs and other electronics.
