Answer 3

In version 3.6.3, navigator.app.exitApp() does work.

Here is where it is called in CordovaView.cs

void CordovaBrowser_ScriptNotify(object sender, NotifyEventArgs e)
{
    string commandStr = e.Value;

    string commandName = commandStr.Split('/').FirstOrDefault();

    if (browserDecorators.ContainsKey(commandName))
    {
        browserDecorators[commandName].HandleCommand(commandStr);
        return;
    }

    CordovaCommandCall commandCallParams = CordovaCommandCall.Parse(commandStr);

    if (commandCallParams == null)
    {
        // ERROR
        Debug.WriteLine("ScriptNotify :: " + commandStr);
    }
    else if (commandCallParams.Service == "CoreEvents")
    {
        switch (commandCallParams.Action.ToLower())
        {
            case "overridebackbutton":
                string arg0 = JsonHelper.Deserialize<string[]>(commandCallParams.Args)[0];
                this.OverrideBackButton = (arg0 != null && arg0.Length > 0 && arg0.ToLower() == "true");
                break;
            case "__exitapp":
                Debug.WriteLine("Received exitApp command from javascript, app will now exit.");
                CordovaBrowser.InvokeScript("eval", new string[] { "cordova.fireDocumentEvent('pause');" });
                CordovaBrowser.InvokeScript("eval", new string[] { "setTimeout(function(){ cordova.fireDocumentEvent('exit'); cordova.exec(null,null,'CoreEvents','__finalexit',[]); },0);" });
                break;
            case "__finalexit":
                IsExiting = true;
                // hide the browser to prevent white flashes, since about:blank seems to always be white
                CordovaBrowser.Opacity = 0d; 
                CordovaBrowser.Navigate(new Uri("about:blank", UriKind.Absolute));
                break;
        }
    }
    else
    {
        if (configHandler.IsPluginAllowed(commandCallParams.Service))
        {
            commandCallParams.Namespace = configHandler.GetNamespaceForCommand(commandCallParams.Service);
            nativeExecution.ProcessCommand(commandCallParams);
        }
        else
        {
            Debug.WriteLine("Error::Plugin not allowed in config.xml. " + commandCallParams.Service);
        }
    }
}

navigator.app.exitApp(); has been available in Apache Cordova WP8 projects since 3.4.0

<div onclick="navigator.app.exitApp()">Exodus</div>

Answer 5

You can create a simple plugin. Add file ExitApp.css to your platforms/wp8/Plugins folder with:

using System.Windows;

namespace WPCordovaClassLib.Cordova.Commands
{
  class ExitApp : BaseCommand
  {
    public void execute(string options)
    {
        Application.Current.Terminate();                        
    }
  }
}

edit your platforms/wp8/config.xml and add to the widget tag:

<feature name="ExitApp">
  <param name="wp-package" value="ExitApp" />
</feature>`

then from you javascript call:

cordova.exec(null, null, "ExitApp", "execute", []);

You can use it in combination with backbutton event to close the app when the user clicks on backbutton in the main page:

function goBack(e){
  if(isInMyMainPage()) cordova.exec(null, null, "ExitApp", "execute", []);
}
document.addEventListener("backbutton", goBack, false)

But it basically says that windows phone 8 apps shouldn't be programatically exited.
