【问题描述】：
如果您花时间在 Google 上搜索“Android Facebook SDK”，您会立即找到官方的 Android Facebook SDK：http://github.com/facebook/facebook-android-sdk
在一个项目中使用过它，我可以说它有点粗糙，因为基于 oAuth / Graph API 的新东西还很年轻，但稍加调整就可以很好地工作。

你能在代码上添加一些描述吗？它需要任何外部罐子吗？谢谢你..
我用一个简单的示例代码详细解释了这个过程。你可以在这里找到它： http://developer.blog.appxtream.com/?p=34
