Alongside its release of a native Android app, Facebook is bringing its SDK 3.0 for Android developers out of beta today. The Facebook SDK for Android lets app developers on the platform integrate social functions into their apps by calling Facebook API's and embedding their functions. This means simple actions like connecting a Facebook account to another app or calling up a friend or location list will be easier to implement and use. For example, users will be able to log-in to their Facebook account without ever leaving the primary app -- really cool stuff.
Facebook says the beta version of the SDK was downloaded over 80,000 times since it was released, so let's hope that some of those developers give it a closer look and use the tools to their advantage. This isn't something most end-users will be dealing with, but we all want this regardless. When developers have better tools, they provide an improved experience for all of us.
