memory problems on Titanium app

Question

I'm developing an app in Titanium that needs to work on android and IOS, but I'm getting some memory problems.

In my app.js file I have this:

var win = Ti.UI.createWindow({
    backgroundColor : 'white',
    url : 'Home.js'
});

win.open();

Ti.App.View = [];

The Ti.App.View array is tu keep a reference to all my container views along my project so I can close them or check if they are already visible.

Then in my Home.js file I have some buttons to open some views. Ex:

var view = Ti.UI.createView({
    height : deviceHeight,
    width : deviceWidth,
    backgroundColor : 'white'
});
Ti.UI.currentWindow.add(view);

var viewMenu = Ti.UI.createView({
    layout : 'vertical',
    width : deviceWidth * 0.20,
    backgroundColor : 'transparent',
});

view.add(viewMenu);

viewMenu.addEventListener('click', function() {
    var Favorites = require("Eventos");
    Events.AddLayout();
});

This is the way how I add a new layout to the same window.

Then on my Events.js file I have a function like this and a global event :

exports.AddLayout = function(e) {
    //adding all my layout.....
}

Ti.App.addEventListener('Update', function() {
   // due something in hear
});

My question is how can I remove all Ti.UI objects created in the AddLayout function from memory when I press back button? And how can I remove the global event created by the Events.js file?

I have tried to reference te container view to null but it has not solved my problem.

don't put them in the Ti.UI namespace, put them in Alloy.Globals (if you use Alloy) or even better, make a lib to handle it. — Rene Pot

Have you considered developing this with Alloy? It uses a commonJS approach and would remove the need to use Global events like this and structure the app in a way that's easier to represent views, open and destroy views etc.

If not, try to avoid using Global Event listeners -- typically there's no need to use these and they'll end up causing all kinds of memory leaks.
