Facebook Connect Android SDK
Facebook have released a Facebook Connect Android SDK, which introduces an open source Java library for integrating Facebook into Android mobile applications.
With the SDK, developers can prompt users to log into their Facebook account and grant access permission to an application, through an embedded WebKit WebView that uses the OAuth 2.0. API requests can also be made with the SDK. These authenticated requests are done through the OAuth access token. A number of WebView html dialogues for user interactions are supported by the SDK.
Please see the project’s github for more information, and to download the kit.
