Since Android surpassed the iPhone to become the most popular smartphone in the market last year, it was only a matter of time before the Google OS would also become the most popular platform for developers. But not only that, app development on the Android is now the most profitable. To the point that developers are pulling advertising dollars out of iOS based apps and doubling down on the Bot.

Apps not only generate sales, but also advertising and in-app purchase as part of their revenue trifecta. And many apps developers are finding that the larger Android footprint is translating to greater in-app purchases, as well as up to three times more ad clicks within Android apps. Coupling this with three times as many downloads, and the temptation to focus solely on Android is easy to embrace.

“We’ve just been blown away,” says Spacetime CEO Gary Gattis. “Android has become our primary interest.”

Spacetime is a company that has made the conscious decision to follow the money by taking all their advertising out of the iOS version of their popular Pocket Legends game and place it in the Android platform. The thinking is, that with Android’s focus on the gaming community, and the fact that more users play games on Android handsets than iOS handsets, Spacetime can be a big fish in a small pond. But the pond is getting bigger, as Google recently announced it was up to 150,000 applications in the Android Market, and is well on pace to surpass iOS by 2014.

“In some ways, it’s kind of like the wild, wild West,” Gattis says, “but that’s where the gold rush people made their claim…”
