在调用RequestProductPurchaseAsync WP8.1应用程序崩溃 [英] WP8.1 application crashes on calling RequestProductPurchaseAsync

问题描述

我写的音频播放器的对的的Windows Phone 8.1（运行）的我用 IBackgroundTask 为音频。

I'm writing Audio Player for Windows Phone 8.1 (Runtime) and I use IBackgroundTask for audio.

我想使用应用程序内购买，但应用程序在调用崩溃

I want to use in-app purchase, but applications crashes on calling

var result = await CurrentAppSimulator.RequestProductPurchaseAsync(ProProductId);

无任何异常。

without any exceptions.

这方法try-catch块中调用。

This method is called within try-catch block.

它发生时，应用程序已经启动 IBackgroundTask BackgroundMediaPlayer.Current 电话后几秒钟后（发生> RequestProductPurchaseAsync ）。

It happens when application already start IBackgroundTask by calling for BackgroundMediaPlayer.Current (happens after few seconds after call RequestProductPurchaseAsync).

如果我称之为 RequestProductPurchaseAsync 后无需调用启动应用程序 BackgroundMediaPlayer.Current ，它正常工作。

If I call RequestProductPurchaseAsync after start app without calling BackgroundMediaPlayer.Current, it works normally.

什么的这种行为的原因是什么？有解决这个问题的一些方法？

What the reason of this behaviour? There are some ways to solve this problem?

推荐答案

我有同样的问题，只是应用程序崩溃，没有任何的异常。与 CurrentAppSimulator 发生以及 CurrentApp 。

I am having the same problem, app just crashes, no exception thrown. Happens with CurrentAppSimulator as well as CurrentApp.

只有我想出的解决办法是杀死底色任务

The only solution I came up with was to kill the Backround task

BackgroundMediaPlayer.Shutdown()

使得IAP之前。请确保您还放了一点延迟调用shutdown后，有时还应用程序崩溃，没有它（但不经常，所以我想有在关机过程中有一些延迟）

before making the IAP. Make sure you also put in a bit of delay after calling shutdown, sometimes the app still crashed without it (but not as often, so I guess there was some delay during the shutdown process)
