在Android应用程序中使用Facebook SDK只会让我的日子变得更糟。我似乎不时松开会话，哈希有时似乎不对。当前错误表示hashkey * 与注册的密钥不同。哪个不正确，hashkey在他们的平台上注册了应用程序（该应用程序也是公开的）。
这是我用来连接Facebook的课程。我选择登录后，我得到说明权限的对话框（想看到朋友列表..），然后我选择确定或取消..没有发生任何事情。会议结束。

希望有人注意到我的错误，因为我现在不明白这一点。感谢
答案 0 :(得分：1)
尝试调用Session.getActiveSession而不将其指定给Session对象。这应该会触发回调。然后在onSessionStateChange(...)方法中，执行条件检查会话是否已打开。
在onCreate(...)进行所有会话检查，如果将其移至onSessionStateChange(...)，可以更好地工作，前提是您可以触发回调。
编辑：尝试手动将回调设置为LoginButton。我认为.setCallback(...)有一个LoginButton方法。我不太可能在不久前从按钮触发回调。
