com.facebook.FacebookException: Cannot pass a publish or manage permission (email) to a request for read authorization

这是我的活动代码：

解决方法 您不能调用openForPublish,除非您的应用程序已经被首先授予了基本权限.

将您的PERMISSIONS列表分成PERMISSIONS_READ和PERMISSIONS_PUBliSH,并将“电子邮件”放入PUBliSH方面.然后调用openForRead,然后在会话打开时requestNewPublishPermissions.
