在Android中通过Facebook SDK登录

Question

我正在使用Facebook SDK通过我的应用程序登录。 我遵循的代码在<https://developers.facebook.com/docs/android/login-with-facebook/>

但是当我单击按钮“使用facebook登录”时 ，按钮没有改变。 该按钮应更改为“注销” 。 我在日志猫中得到关注

Log cat未显示“登录”已执行。

我建议您使用easyfacebookandroidsdk.jar库，逐步执行此过程 。

顾名思义，它比facebook sdk容易。 通过创建一个新项目来尝试此操作。
