SAN FRANCISCO -- Kicking off Google I/O on a high note, executives confirmed that there have been 900 million activations for devices running Android so far.
Two years ago, Google revealed there were at least 100 million activations for Android. A year ago, Google celebrated 400 million.
"The momentum has been breathtaking since then," said Sundar Pichai, senior vice present of the Android, Chrome and Apps teams, during Wednesday morning's keynote.
To any fragmentation naysayers, Pichai described it as "an extraordinary ecosystem achievement," but quipped to laugher that there's still a long way to go.
Furthermore, there had been 48 billion application installs on Google Play.
Without revealing a specific price tag, Hugo Barra, vice president of Android product management at Google, added that revenue per user is 2.5 times what it was a year ago, globally.
