In mid Dec. of 2012, Facebook took their SDK 3.0 for Android out of beta, which means it began to be fully supported, giving greater access and tools for Android and Native Login.
The new Facebook SDK helps developers and app designers build social Android apps by giving native UI controls, simplifying session management, and improving API support--three valuable elements for building dynamic applications and innovation with third-parties.
This expanded tool-kit helps Facebook users gain a consistent experience by giving app developers access to common features.
