Welcome to the Android Open Source Project!

Android is an open-source software stack for a wide range of mobile devices and a corresponding open-source project led by Google. Open software platform for mobile development. Google's Android and Apple's iOS are operating systems used primarily in mobile technology, such as smartphones and tablets. Android, which is Linux-based and partly open source, is more PC-like than iOS, in that its interface and basic features are generally more customizable from top to bottom.  Android was founded in Palo Alto, California in October 2003 by Andy Rubin, Rich Miner, Nick Sears and Chris white who work at “Google” to develop. Android was bought by “Google” in 2005. The primary purposes of Android are to create an open software platform available for carriers, OEMs, and developers to make their innovative ideas a reality and to introduce a successful, real-world product that improves the mobile experience for users.
