NavigationGroup android in titanium

I have the following NavigationController that lives in android and iphone folders:

Android

var NavigationController = function() {
    var self = this;

    self.open = function(windowToOpen) {
        //make "heavyweight" and associate with an Android activity
        windowToOpen.navBarHidden = windowToOpen.navBarHidden || false;

        if(!self.rootWindow) {
            windowToOpen.exitOnClose = true;
            self.rootWindow = windowToOpen;
        }

        windowToOpen.open();
    };

    self.close = function(windowToClose) {
        windowToClose.close();
    };

    return self;
};

module.exports = NavigationController;

iphone

var NavigationController = function() {
    var self = this;

    function createNavGroup(windowToOpen) {
        self.navGroup = Ti.UI.iPhone.createNavigationGroup({
            window : windowToOpen
        });
        var containerWindow = Ti.UI.createWindow();
        containerWindow.add(self.navGroup);
        containerWindow.open();
    };

    self.open = function(windowToOpen) {
        if(!self.navGroup) {
            createNavGroup(windowToOpen);
        }
        else {
            self.navGroup.open(windowToOpen);
        }
    };

    self.close = function(windowToClose) {
        if(self.navGroup) {
            self.navGroup.close(windowToClose);
        }
    };

    return self;
};

module.exports = NavigationController;

Then you can just use it (you will automatically get the correct option depending on the execution time):

var NavigationController = require('NavigationController')
var MyView = require("ui/MyView");

var controller = new NavigationController();
var myView = new MyView(controller);
controller.open(myView);

You can continue to open windows, and they go on the stack. Please note that I passed the controller to the first view. You keep doing this:

controller.open(new SecondView(controller));

back . , , :

controller.close(myView);
