Android

what is ardroid 

Android (stylized as 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 ondirect 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 notebooks, game consoles, digital cameras, and other electronics

The main hardware platform for Android is the ARM (ARMv7 and ARMv8-A architectures), with x86 and MIPS architectures also officially supported in later versions of Android. The unofficial Android-x86 project provided support for the x86 architectures ahead of the official support.^[6][90] MIPS architecture was also supported before Google did. Since 2012, Android devices with Intelprocessors began to appear, including phones^[91] and tablets. While gaining support for 64-bit platforms, Android was first made to run on 64-bit x86 and then on ARM64. Since Android 5.0 "Lollipop", 64-bit variants of all platforms are supported in addition to the32-bit variants.

Software stack

On top of the Linux kernel, there are the middleware, libraries and APIs written in C, and application softwarerunning on an application framework which includes Java-compatible libraries. Development of the Linux kernel continues independently of other Android's source code bases.
