The version history of the Android operating system began with the release of the Android beta in November 2007. The first commercial version, Android 1.0, was released in September 2008. Android is a mobile operating system developed by Google and the Open Handset Alliance, and has seen a number of updates to its base operating system since its original release. These updates typically fix bugs and add new features. Since April 2009, each Android version has been developed under a codename based on a dessert or sweet treat. These versions have been released in alphabetical order: Cupcake, Donut, Éclair, Froyo (frozen yogurt), Gingerbread, Honeycomb, Ice Cream Sandwich, and Jelly Bean. The pre-release versions of Android were dubbed Astro and Bender, but these names could not ultimately be used for trademark reasons. The most recent update to the Android OS was Jelly Bean v4.1, which was released in June 2012.

Google’s Hugo Barra and Dave Burke announce the latest Android OS update, Jelly Bean, at Google I/O in San Francisco. The new OS features offline voice typing, an update to notifications, an enhanced camera app, and better touch-screen responsiveness.
