SAN FRANCISCO - Some 900 million smartphones and tablets running Google Inc's Android software have been activated since the platform's inception in 2010, executives said at the company's annual developers' conference on Wednesday.

Google said revenue from Android, the software used by Samsung and other mobile device makers that competes with Apple Inc, is also gaining momentum.

Google executives said revenue per user for Android applications developers is now 2-1/2 times its year-earlier level.
