Seven comes right after six.
Conspicuously absent from yesterday's Android Nougat announcement shenanigans was any mention of which version number we'd be jumping to next. If you've been following Android for a while, you'll know that version numbers have been somewhat... inconsistent... in past eras (lookin' at you, ICS/Jelly Bean/KitKat). And so there's been speculation that Nougat might get a number other than the super-obvious 7.0.
Fret no more, Android fans: Google has let slip in (of all places) its YouTube video description for the Nougat unveiling that it is indeed Android 7.0.
"On June 30th, 2016 we unwrapped our latest treat, Android 7.0 Nougat."
Which is the obvious choice after 5.0 in 2014 and 6.0 in 2015. (And it also tallies with a small uptick in traffic from 7.0 that we've been seeing in our server logs this month.)
So there we have it: Android 7.0 Nougat.
