Thanks to a number of spectacular smartphones and some super cheap tablets, Android adoption continues to rise. According to Google chairman Eric Schmidt, who is speaking at AllThingsD’s Dive Into Mobile conference today, 1.5 million Android devices are being activated each and every day.

That figure has risen from the 1.3 million activations per day that Google reported last fall, and the 1.4 million per day as of last month.

Schmidt says that Google is now on track to activate one billion Android devices by the end of 2013.

“Our goal with Android is to reach everyone,” he said. “We’ll cross one billion Android devices in six to nine months. In a year or two we’ll hit two billion.”

Last month, Google CEO Larry Page announced on Twitter that 750 million devices had been activated so far, so there’s still a fair way to go just yet.

Schmidt believes that the key to future Android growth is hitting the $100 price point. The likes of Amazon and Google have led the way with affordable devices up until this point, with the $199 Nexus 7 and Kindle Fire, and the $349 Nexus 4. But no one has gotten quite as low as $100 yet. At least not with anything you’d actually want to buy.

“If low-end smartphones are inexpensive now, imagine just how inexpensive they’ll be a few years from now,” Schmidt said. “And that’s how we’re going to hit the next billion devices.”
