[AC-4015] Change Background Color for WebView Loading White Screen

When I load a Window with a WebView i.e. var win = Titanium.UI.createWindow({ backgroundColor: Alloy.Globals.colors.Yellow }); var webView = Titanium.UI.createWebView({ url : local_html_file, backgroundColor : Alloy.Globals.colors.Yellow, }); win.add(webView); win.addEventListener('close', function() { win.removeEventListener('close', function() {}); win.remove(webView); webView = null; win = null; }); win.open(); . . . Now in this case A yellow background displays for a fraction of second... then white screen displays for a second until the Window(with webview) loads completely Then the Window loads With the webview . . I want to change the background of in between shown white screen to Yellow instead. (From : When window with webview is loaded and webview in over written to window and white screen is shown To : When WebView is loaded) How can this be done? (Please mention any titanium core library file change if required to perform this action for now)
