Google just kicked off this year’s Google I/O conference and we’re in store for quite a show. The keynote is scheduled to run for three hours — yes, three hours — and Google SVP Sundar Pichai started off the show by announcing cumulative Android activations have now reached 900 million. Google also announced Google Play has topped 48 billion app installs, including 2.5 billion installs in the last month alone. Revenue per user for Android apps is now 2.5 times more than it was a year ago, according to Google.
