Android (Android) is an open source mobile device operating system based on Linux, mainly used in smartphones and tablets. The Android system was originally developed and produced by Andy Rubin and others. The initial purpose of developing this system was to create an advanced operating system for digital cameras; but later it was found that the market demand was not large enough, and the smartphone market grew rapidly. So Android was transformed into an operating system for smartphones. It was acquired by American technology company Google in August 2005.
