Windows phone 8.1 应用程序在打开共享后立即崩溃 ui

Question

我的 windows 8.1 应用程序中有 2 个页面。他们都有一个共享按钮。在我主页的第一页上，共享按钮按预期工作，即打开共享 ui（如下所示）。

但是在我的另一个页面（它有一个用于显示一些修改过的网页内容的网络视图）上，一旦共享 ui 打开应用程序崩溃（有时在打开之前）。我在程序执行期间没有收到任何异常或错误。

当我使用 Visual Studio 将应用程序部署到我的 phone 时，它不会崩溃，但在运行之后（没有 visual studio）应用程序开始崩溃。

这显示了我如何打开共享 UI (Find Full Code for the page here)

try
{
   Windows.ApplicationModel.DataTransfer.DataTransferManager.ShowShareUI();
}
catch(Exception ex)
{
   //Code to handle exception
}

这是编译时的部分输出(find full output here)

有什么问题？

Answer 1

挂起可能有问题（调试时没有调用）。

如果您尝试调试挂起事件，最好的办法是使用 VS 中的 Lifecycle events 选项卡（如 this answer 中的图片所示）。

问题还可能是您在导航到不可序列化的页面时传递了一些参数。在这种情况下，当应用程序被挂起时，SuspensionManager 可能会抛出异常。
