Andy Rubin: Google activates 300,000 phones every day

For Google, the royalties and sales shares of the platform is not as important as having it out there, seamlessly integrating into their online offering. As such, they don't even have these numbers, they just see how many people connect.
For them it basically means: "we have 300k more people every day who are surfing our cloud".

So I'm guessing that "activation" just means a new device (that can access mobile internet) being sold to an end user through a retail channel?
Math: 14.1 million / (1/4 * 365) days ~= 150,000 phones
There are many devices, though, that don't use Google's activation but which use Android. It's pretty hard to estimate how many.
But since those are the ones being advertised by big brands and sold through networks I'd guess the undercount isn't that much.
