在Windows Phone 8.1共享合同中显示Viber、Whatsup

Question

嗨，我正在开发一个应用程序，通过Windows Phone 8.1中的共享合同共享图片。我的代码是

DataTransferManager dataTransferManager = DataTransferManager.GetForCurrentView();
dataTransferManager.DataRequested += new TypedEventHandler<DataTransferManager, DataRequestedEventArgs>(this.DataRequested);

和

private async void DataRequested(DataTransferManager sender, DataRequestedEventArgs args)
{
    DataRequest request = args.Request;
    request.Data.Properties.Title = "Unscramble this";
    request.Data.Properties.Description = "";
    request.Data.SetText(string.Format("Scrambled word is {0} and clue is {1}. Help me to unscramble this \r\n(via Unscramble Plus for Windows Phone)",scrambledString.ToUpper(),selectedMeanings.ToUpper()));
    DataRequestDeferral deferral = request.GetDeferral();

    // Make sure we always call Complete on the deferral.
    try
    {
        //StorageFile logoFile = await Package.Current.InstalledLocation.GetFileAsync("Assets\\Logo.png");

        StorageFile imagefile = await KnownFolders.PicturesLibrary.GetFileAsync("pic.png");
        List<IStorageItem> storageItems = new List<IStorageItem>();
        storageItems.Add(imagefile);
        request.Data.SetStorageItems(storageItems);
    }
    finally
    {
        deferral.Complete();
    } 
}

其中显示了如下共享合同(仅包括Facebook、邮件应用程序)

但是，如果你在Windows Phone (http://www.windowsphone.com/en-us/store/app/sendtiment-cards/9c389cc5-5c00-4f8e-8bd4-e6fbb5040c24)的发送应用程序中看到，它显示了许多应用程序，如Viber，Whatsapp，Twitter。

如何在我的应用程序的共享合同中获得这些Viber，Whatsapp之类的应用程序？

编辑：(添加)当我删除request.Data.SetText(string.Format("Scrambled word is {0} and clue is {1}. \r\n(via Unscramble Plus for Windows Phone)",scrambledString.ToUpper(),selectedMeanings.ToUpper()));行时，它显示OneDrive。

这可能会有所帮助，也要确保你共享的是哪种类型的数据，因为应用程序只会在内容类型匹配时显示，

例如，whatsapp仅在您共享视频、图像而不是电话联系人时才会显示。

Answer 2

如果您使用的是Universal-App，Whatsapp将不会显示。WhatsApp是一个WP8.1Silverlight-App。这就是问题所在！
