Confirmábamos ye ago the new version of Android would like KitKat name. However, there were some doubts, as if the company itself would have used this name under license from the chocolate or just what had taken without permission. KitKat, the brand, has reached an agreement with Android.
The proof of that is found in the KitKat Twitter page, then customized the bottom of the page, the bottom of the image, and self-image of the user, with the Android 4.4（Lenovo A820 ） KitKat logo. This logo is neither more nor less than Andy become a chocolate divided into bars. It seemed crazy that Google had taken the name KitKat without the permission of the company, because it would have been a lot of legal trouble. However, now it is very clear that they had reached an agreement.
Moreover, not only Google could have opted for the name KitKat, but above could be the brand of chocolates which paid for the new face of Google operating system for smartphones and tablets. In fact, this is more than likely. The worldwide advertising is really expensive, and it seems logical that a company that now dominates the online advertising market, we have given this a KitKat. Chances are that the agreement between Google and KitKat involves the latter has to pay the company's Mountain View for the use of the name.
This could set a precedent for the future. The next version of Android will start with the letter L. We could find ourselves with something like Lacasitos Android 5.0（Lenovo A830 ）, Android 7.0 or Nutella. Obviously, these are all speculations, but it is clear that open the door to a new type of advertising and sponsorship.
