我已经阅读了一些包含该问题的主题，但没有一个答案是有用的，或者主题最终没有得到解决。

所以我的应用程序在模拟器上运行良好，但在设备上运行不正常（HTC Trophy 是否重要？）。我正在捕捉这样的异常：

我应该怎么办？我应该从哪里开始修复它？

要查看的事项清单：

  • -object是否URI设置了UriKind.Absolute属性？
  • 我的手机是否有数据连接（例如 Facebook、Internet Explorer 等其他应用程序是否可用）？
  • 如果是这样，我可以在网络浏览器中打开 URL（假设它是一个GET-request）并找到它吗？

如果所有这些问题的答案都是肯定的，请尽可能尝试使用第二台设备并尝试重现问题。如果它仍然存在，请查看服务器端，也许缓存出于某种原因搞砸了。

快乐（错误）狩猎！
