[UWP] [C＃] AppMemoryUsageLimitChanging事件未在后台触发 [英] [UWP][C#]AppMemoryUsageLimitChanging event not firing in background

问题描述

您好！



我使用本文中的代码https://docs.microsoft.com/en-us/windows/uwp/launch- resume / reduce-memory-usage。

当应用程序运行事件被触发但是当我将应用程序发送到后台时，我的lumia 650事件未被触发（没有附加VS）。我使用hockeyapp客户端跟踪事件（也许它无法在后台显示，但我无法证明）。

所以我需要帮助解释为什么（不）发生。

感谢您的帮助。

Mr1Penguin，

>>当应用程序运行事件被触发但当我将应用程序发送到后台时，我的lumia 650事件未被触发（没有附加VS）。

你能告诉我你如何测试 AppMemoryUsageLimitChanging 事件？

在我的测试中，我按照  文档 以及将一些文本写入  AppMemoryUsageLimitChanging   handler，
然后在visual studio外运行应用程序并将应用程序切换到后台。最后，我可以在应用程序的本地文件夹中找到该文件并写入文本。 

祝你好运，

Hello!

I use code from this article https://docs.microsoft.com/en-us/windows/uwp/launch-resume/reduce-memory-usage .
When application running event is fired but when I send application to background on my lumia 650 event not fired(without attached VS). I track event using hockeyapp client(maybe it can't show this in background but I can't prove it).

So I need help to figure why it's (not) happening.

Thanks for your help.

Hi Mr1Penguin,

>>When application running event is fired but when I send application to background on my lumia 650 event not fired(without attached VS).

Could you tell me how do you test the AppMemoryUsageLimitChanging event?

In my test, I create an app following the document and write some text into a local file in the AppMemoryUsageLimitChanging handler, then running the app outside of the visual studio and switching the app to the background. Lastly I can find the file in the app's local folder and the text is written into. 

Best regards,

Breeze Liu
