Sergey Shakhnazarov commented on CB-12193: ------------------------------------------ [~ven.guddanti], yes it would be great if you could upload a sample. I tried to reproduce this with a blank WinJS app - issue did not occur for me neither on adding cordova.js after base.js nor on commenting out base.js reference and copying it to the {{www/WinJS/js/base.js}} location. > cordova.js crashes windows app if there is no CoreWindow > -------------------------------------------------------- > > Key: CB-12193 > URL: https://issues.apache.org/jira/browse/CB-12193 > Project: Apache Cordova > Issue Type: Bug > Components: Windows > Environment: Windows 10 > Reporter: venkata guddanti > Priority: Critical > > 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 -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@cordova.apache.org For additional commands, e-mail: issues-h...@cordova.apache.org
