最近,我开始从我的小部件中收到以下错误。我没有做任何改变,我想知道问题可能是什么以及如何解决这个问题。我的小部件根据我为访问第三方客户端信息而创建的服务中的信息进行更新。直到几天前,我才能恢复正常的数据。现在我收到以下错误。
我刚刚尝试在活动(即非小部件)中运行代码,它工作正常。我不确定为什么它在活动中有效,但在小部件中无效。我还在单独的 Intent 中运行对第 3 方网站的访问。
我尝试重新启动模拟器、eclipse 并重新启动设备。我的清单文件具有访问 Internet 的适当权限。该问题最初似乎是网络问题,但我确认我可以从模拟器和设备上的 Web 浏览器访问 URL。该代码几天前才工作。我已经用我的清单文件更新了帖子。代码在调用 parseMyInfo 之前失败。在 OAuth 消费者/提供者调用期间引发异常。
