Earlier today, Google CEO Larry Page announced that Andy Rubin would be stepping down
as head of Android, and Chrome head Sundar Pichai would be taking over. But, Larry also gave some interesting stats on the state of the Android ecosystem, and based on the numbers he gave, it looks like Android is still on track to hit 1 billion activations by the end of 2013.
According to Page, Google has seen 750 million Android device activations to date. It's still not completely clear what this number represents though. Google has said in the past that the number only counts a device the first time it connects to a mobile network, but the existence of WiFi-only tablets, and non-Google Android devices (ie. Kindle Fire, Baidu, etc) haven't been clarified in regards to the number.
Still, it is a very large number, and according to Benedict Evans Google is still on track to hit 1 billion total activations before the end of the year. Evans estimates that 1.4 million Android devices are being activated every day, and by our calculations that puts Android on pace to hit 1 billion activations by mid-September.
