android – java.lang.UnsupportedOperationException：Session：尝试为具有挂起请求的会话请求新权限

概述下面的代码是用于在 android中使用facebookSDK3.0发布状态更新.如果我使用的是UiLifeCycleHelper类,那么它的运行状况良好.但我想在不使用UiLifeCycleHelper类的情况下在facebook中发布状态.我尝试了下面的代码,它在我的logcat中抛出错误,我的应用程序被强制关闭. public class SampleFBPostActivity exten 下面的代码是用于在 android中使用facebookSDK3.0发布状态更新.如果我使用的是UilifeCycleHelper类,那么它的运行状况良好.但我想在不使用UilifeCycleHelper类的情况下在facebook中发布状态.我尝试了下面的代码,它在我的logcat中抛出错误,我的应用程序被强制关闭.

请不要在解决方案中使用UilifeCycleHelper类来帮助我.提前致谢

解决方法 您是否有特殊原因想要使用UilifecycleHelper？那个课程专门为了让你的生活更轻松,所以你不会遇到这样的问题.

如果必须,最简单的方法是查看UilifecycleHelper中的代码,并将它们复制到Activity中的相应方法.

对于您的特定活动,我看到两个错误：

>您无法随时打开会话(直接调用requestNewPublishPermissions,但您需要先打开会话).调用“新会话”不会打开它.>您没有覆盖onActivityResult方法,这是将信息传递回活动会话所必需的.
