Name Confirmed for upcoming new version of Android called Android KitKat

Android KitKat

Prepare for a sweet new treat

Android is the operating system that powers over 1 billion smartphones and tablets. Since these devices make our lives so sweet, each Android version is named after a dessert: Cupcake, Donut, Eclair, Froyo, Gingerbread, Honeycomb, Ice Cream Sandwich, and Jelly Bean. As everybody finds it difficult to stay away from chocolate we decided to name the next version of Android after one of our favorite chocolate treats, Kitkat®!
