Christian Campo commented on CB-12193:
--------------------------------------

I recently tried to run Cordova embedded in a XAML-WebView on Windows 10. The 
check that was introduced by this Jira ticket CB-12193

"Windows.UI.ViewManagement.ApplicationView.getForCurrentView();"

does work and set the isCoreWindowAvailable to true; (I believe it is supposed 
to run in an Exception when run as Embedded WebView)

HOWEVER the next callĀ 

Windows.UI.WebUI.WebUIApplication.addEventListener("resuming", resumingHandler, 
false);

is failing with missing permissions.

What is right procedure ? Reopen this ticket or open a new ticketĀ since this is 
a regression ?

> The back button support in cordova.js crashes windows app. In particular the 
> following line crashes:
> var navigationManager = 
> Windows.UI.Core.SystemNavigationManager.getForCurrentView();
> Putting try catch around it does not help. It crashes deep in the bowels of 
> native code. So I believe there should a fix similar to the following code in 
> WinJS base.js:
>     // If getForCurrentView fails, it is an indication that we are running in 
> a WebView without
>     // a CoreWindow where some WinRT APIs are not available. In this case, we 
> just treat it as
>     // if no WinRT APIs are available.
>     var isCoreWindowAvailable = false;
>     try{
>       _Global.Windows.UI.ViewManagement.InputPane.getForCurrentView();
>       isCoreWindowAvailable = true;
>     }
>     catch (e){
>     }
> You can then skip setting up the back button handler if there is no 
> CoreWindow:
> if (isCoreWindowAvailable)
>       {
>         var navigationManager = 
> Windows.UI.Core.SystemNavigationManager.getForCurrentView();
>         ...
> }
> I am aware that Cordova Windows 10 is not supported in a WebView (i.e. there 
> is no CoreWindow). But WinJS and majority of Windows APIs work. Cordova 4.0.0 
> used to work as well, since there was no back button support in it. Plugins 
> that need CoreWindow (i.e. plugins that show native UI) like Camera etc have 
> issues without it. We have a framework where we proxy these plugins through 
> the main application Window (similar to iOS and Android).
> Please do consider this and incorporate a fix in cordova for Windows 10
