Android is a Linux-based operating system for mobile devices such as smartphones and tablet computers. It is developed by the Open Handset Alliance led by Google.

Google purchased the initial developer of the software, Android Inc., in 2005.The unveiling of the Android distribution in 2007 was announced with the founding of the Open Handset Alliance, a consortium of 86 hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices. The Linux kernel manages the hardware and provides security, resource/file/process management, networking and drivers. A range of libraries sit on top of this kernel to provide functionality such as media playback, 2D/3D graphics, font rendering, data management, and web page rendering.

Android was listed as the best-selling smartphone platform worldwide.

 Foundation of  Android

Android originally began as a product of Android Inc. in 2003 and was founded by a group of people including Andy Rubin, a co-founder of Sidekick phone manufacturer Danger, and Nick Sears, a former vice president at large US mobile phone carrier T-Mobile. In 2005, Google bought the company, and although they knew little about Android’s inner operations, it caused people to speculate whether Google was interested in getting into the mobile phone market.

Key employees of Android Inc., including Andy Rubin, Rich Miner and Chris White, stayed at the company after the acquisition. Not much was known about Android Inc. at the time of the acquisition, but many assumed that Google was planning to enter the mobile phone market with this move.

Android consists of a kernel based on the Linux kernel, with middleware, libraries and APIs written in C and application software running on an application framework which includes Java-compatible libraries based on Apache Harmony. Android uses the Dalvik virtual machine with just-in-time compilation to run Dalvik dex-code (Dalvik Executable), which is usually translated from Java bytecode.

The main hardware platform for Android is the ARM architecture. There is support for x86 from the Android x86 project and Google TV uses a special x86 version of Android.

Security

Android applications run in a sandbox, an isolated area of the system that does not have access to the rest of the system’s resources, unless access permissions are explicitly granted by the user when the application is installed. Before installing an application, the Play Store displays all required permissions: a game may need to enable vibration or save data to an SD card, for example, but should not need to read SMS messages or access the phonebook. After reviewing these permissions, the user can choose to accept or refuse them, installing the application only if they accept.
