The first Android-powered phone isn’t the only big news on the mobile front this week. Applications for the Android operating system are already making their way to market.

On Thursday, Visa announced plans to make mobile payment-related services for the Android platform, while PacketVideo stepped out on Wednesday with news that it would launch CORE, a multimedia application framework that powers more than 260 million devices worldwide, for Android.

Meanwhile, Namco launched PacMan for the Android operating system. Glu Mobile announced that Bonsai Blast, an all-new action-puzzle game, will launch on Android. And Big in Japan announced ShopSavvy, an application designed to help people do comparative shopping via the Android Market.

“There’s money to be made in the Android marketplace,” said Bill Ho, an analyst at Current Analysis. “Developers, while they are intellectually stimulated by programming, at end of the day they are going into this to make money. So what we see is an ecosystem that’s been built for this.”
