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. In November 2007, Google established the Open Handheld Device Alliance with 84 manufacturers, developers, and telecom operators to jointly develop and improve the Android system. Subsequently, Google released the Android version with the Apache free open source license. The original code allowed manufacturers to launch smartphones equipped with Android, and Android gradually expanded to tablet computers and other fields.
