Description

There isn't any good way to know if the user "pauses" an Android app. For example by hitting the home button. Listening for activity pause/resume for a multiple activity app can be really messy. Maybe also hook this feature into the Ti.App.pause(d) event? http://developer.android.com/reference/android/app/Activity.html#onUserLeaveHint()

	var win = Ti.UI.createWindow({
		   backgroundColor : 'red',
		   orientationModes : [Titanium.UI.PORTRAIT],
		   exitOnClose : true,
		   navBarHidden : true
		});
	
	win.addEventListener('open', function(){
		win.getActivity().addEventListener('userleavehint', function()
				{
			Ti.API.info("Activity USER_LEAVE_HINT!!!!");
			});
	});
		 
	win.addEventListener('click', function()
	{	
	   var secondWin = Ti.UI.createWindow({
	      backgroundColor : 'blue',
	      orientationModes : [Titanium.UI.PORTRAIT],
	      navBarHidden : true
	   });
	  
	   secondWin.open();
	});
	win.open();

Pause/resume should only be called when you leave the app, for example pressing the home buttom.

 
   var win = Ti.UI.createWindow({
      backgroundColor : 'red',
      orientationModes : [Titanium.UI.PORTRAIT],
      exitOnClose : true,
      navBarHidden : true
   });
   
   win.addEventListener('click', function()
   {
      var secondWin = Ti.UI.createWindow({
         backgroundColor : 'blue',
         orientationModes : [Titanium.UI.PORTRAIT],
         navBarHidden : true
      });
    
      secondWin.open(); // Ti.App pause/resume will NOT fire here! Good!
   });
   win.open();
   
   Ti.App.addEventListener('pause', function()
   {
      Ti.API.log("PAUSE!!!!");
   });
   
   Ti.App.addEventListener('resume', function()
   {
      Ti.API.log("RESUME!!!!");
   });

This event is for the activity and will be fired when the activity goes to the background when opening the 'secondWin' which won't help providing the 'app' 'pause' event.

A new event 'userleavehint' is added to the activity https://github.com/appcelerator/titanium_mobile/pull/4647
