Over at the Android Developer’s blog, they’ve announced that in-app purchases are now available for testing in their apps. Developer Eric Chu wrote that in-app purchases are coming to Android handsets next week, as the company promised in February.

In-app payments give Google another feather in its cap as it competes with Apple in the mobile marketplace.

In the post, Chu said that it is "absolutely essential" that developers look at Google’s security guidelines before putting the functionality in their apps. Google developers “must have a Google Checkout Merchant account to use the in-app billing service,” according to the developers document.

It will be interesting to see whether Google’s runs into the same in-app problems as Apple’s App Store.
