Smartphone sales have been accelerating each year. Roughly:
2006 - 80 million
2007 - 100 million
2008 - 140 million
2009 - 170 million
2010 - 295 million
2011 - 485 million
2012 - 675 million
2013 - 900 million (forecast)
So it's easy to believe there's currently over 1 billion users.
There are no Android based feature phones at this time. (There has been talk of doing some, but AFAIK nothing yet.)
The activations number includes tablets, and is predicted to occur by the end of this year.
Isn't that 1 billion activations
TOTAL, since inception? I believe that is what Page said during his March interview. (Just Googled it. Here is the quote):
Imagine, if you will, that every man, woman, and child in Europe owned an Android device. That still wouldn't account for every device that's been made, sold, and activated, according to the latest blog post from Google CEO Larry Page. In the same message that revealed Andy Rubin would be leaving his position as the head of Android development, Page mentioned almost in passing that Android had surpassed 750 million activated devices, including smartphones, tablets, and various other gadgets.
So in March, Android had activated 750 million Android capable devices since the first phone was introduced running Android back in 2008.
As for feature phones running Android, what about the Galaxy Pro in 2011, Huaweis Impulse in 2011, LG Optimus T and S in 2012, plus a host of others listed as feature phones by the manufacturer running Android? I think many people envision a 2 inch, epaper style lcd display and a hard button T9 dialpad as a feature phone. This is not the case, at least according to the manufacturers of the phones. Not trying to argue or come across as an ass, just explaining my interpretation from my previous post and why I said what I did.

Those sales and activation figures for Android (and also for iOS if they exist) don't take into account that a lot of people get a new phone every year, or have multiple phones (if they do please correct me)
So there may be 900 million activations, but that doesn't mean 900 million *unique* activations.
Heck some people have more than one smartphone at the same time.
Actually, it does mean unique activations. If the IMEI # from a device checks in with Google's servers, it's done. Can't be activated again. However, Google has introduced a new method to ensure that an activated phone is being used and not sitting collecting dust somewhere, by only counting phones that check in to Google Play every month.
From Google's developer website in April:
Mountain View noted the change to activations on its Android developer site, writing: Beginning in April, 2013, these charts are now built using data collected from each device when the user visits the Google Play Store. Previously, the data was collected when the device simply checked-in to Google servers. We believe the new data more accurately reflects those users who are most engaged in the Android and Google Play ecosystem.
