What are the reason for the naming conventions of version of Android?

As it turns out, all Android operating systems are named after desserts. And, just in case that wasn't nerdy enough for you, Google put these sugary names in alphabetical order. Here's the edible Android timeline: Cupcake, Donut, Eclair, Froyo, Gingerbread and finally -- at least for now -- Honeycomb.

Which OS platform has a convention of naming the versions after desserts?

Google operating systems are always named after a sweet, like Cupcake, Donut, KitKat or Nougat. A Google spokesperson once said, "Android powers over one billion smartphones and tablets. Since these devices make our lives so sweet, each Android version is named after a dessert".
