which file to use sencha-touch.js or sencha-touch-debug.js or sencha-touch-all.js or

[Joz Michael]

I am trying a basic demo app with below code...

Ext.application({
    name : 'MyApp',
    
    launch : function () {
        var MyPanel = Ext.create("Ext.Panel", {              
            html : "Test APP..."     
        });
        
        Ext.Viewport.add(MyPanel);
    } 
});

In index.html, if i use

 script src="lib/sencha-touch.js" type="text/javascript" (or) script src="lib/sencha-touch-debug.js" type="text/javascript"

Nothing is rendered on browser screen(Chrome 18.0) In index.html, if i use

  script src="lib/sencha-touch-all.js" type="text/javascript" (or)  script src="lib/sencha-touch-all-debug.js" type="text/javascript"

Content is rendered on browser screen(Chrome 18.0) Which JS file should we include in HTML file...? In one of Forum(http://www.sencha.com/forum/showthre...encha-touch.js) Jacky Nguyen advised to use "sencha-touch.js" for Production and "sencha-touch-debug.js" for development... Unfortunately usage of these JS file not working for my code...... Whats going wrong............???? Is there any problem with my code or any problem with JS files...
