Android named the next version of its popular mobile OS KitKat, after the chocolate bar. The next version of Android will be called KitKat after the Nestle chocolate bar, and not Key Lime Pie, as was predicted for months, Google said Tuesday. The news was an unexpected twist to many Android fans, who had expected the next big release would be numbered Android 5.0 and would be called Key Lime Pie, in keeping with Google's pattern of picking an Android update named after a sweet treat, starting with the next letter in the alphabet.
