Android N version number seemingly revealed by Samsung15
Samsung recently released a new SDK (software development kit) for its MultiWindow feature - found on many Galaxy devices - mentioning that this comes with "Android N (7.0) compatibility." Since Samsung is one of Google's most important partners, it probably knows more about Android N than us, so we're inclined to believe that 7.0 is Android N's correct version number.
Of course, we can't say that the version number of Android N is of great importance. What matters more is the confectionery-themed name that this iteration of Android will have - because that's what's going to show up more prominently in marketing materials. Google has plenty of names to choose from, including Nougat, Nutella, Nanaimo bar, Nut roll, Neapolitan ice cream, and so on.
