正如之前为片段使用的 Facebook 登录名一样，它工作得很好，所以现在随着需求的变化而改变了 facebook 登录活动，所以，我们有正常的 android 按钮，单击该登录对话框将出现用于用户交互以提供用户名和密码和当登录成功时，使用 executeme 请求获取用户详细信息。每个代码都已完成，但单击按钮对话框时未出现但 onsessionstate 更改日志显示输出为
首先显示 OPENING 比显示 LOGIN FAILED CLOSED
在 facebook 应用程序开发站点中提到的登录 facebook 所需的所有步骤都已执行，并且所有需要的类和元数据信息也在 andriod 清单文件中给出。
这里是登录的活动类
public class ResgistrationApp extends Activity {

Log.e("会话状态", ""+状态); 这里显示 LOGIN FAILED CLOSED。
