Question

我是Android应用中的菜鸟。我正在创建一个应用程序，使用https://developers.facebook.com/docs/android/send-requests中定义的方法向我的Facebook好友发送应用请求。现在我无法登录并访问我的应用程序。提供用户名和密码后，我登录到Facebook，我的Facebook应用程序请求许可。按下确定后，它不会重定向到发送请求窗口，而是再次向我显示登录窗口，就像我没有登录一样。

这是我的完整代码。请帮帮我。

Answer 1

我发现并回答了我的问题，现在是：

在ensureOpenSession方法中，用

替换条件

if (Session.getActiveSession() != null || Session.getActiveSession().isOpened())

并在onSessionStateChanged方法中，

替换

if (state.isOpened())

与

if (session.isOpened() && state.isOpened())
