[TIMOB-12398] Android: TabGroup activity should work like Window activity

var win = Ti.UI.createWindow({
  fullscreen: true
});

var activity = win.activity;

activity.onCreateOptionsMenu = function(e){
  var menu = e.menu;
  var menuItem = menu.add({ title: "Item 1" });
  menuItem.icon = "item1.png";
  menuItem.addEventListener("click", function(e) {
    Ti.API.debug("I was clicked");
  });
};

win.open();

var tabGroup = Titanium.UI.createTabGroup();

var win1 = Titanium.UI.createWindow({
	title : 'Tab 1',
	backgroundColor : '#fff'
});
var tab1 = Titanium.UI.createTab({
	icon : 'KS_nav_views.png',
	title : 'Tab 1',
	window : win1
});
var addMenu = function() {
	tabGroup.activity.onCreateOptionsMenu = function(e) {
		var menu = e.menu;
		var menuItem = menu.add({
			title : "Item 1"
		});
		menuItem.icon = "item1.png";
		menuItem.addEventListener("click", function(e) {
			Ti.API.debug("I was clicked");
		});
	};
}
addMenu(); // To work around issue, comment out this line and 
           // uncomment the addEventListener call below.
/*
tabGroup.addEventListener("open", function() {
	addMenu();
	tabGroup.activity.invalidateOptionsMenu();
});
*/
tabGroup.addTab(tab1);
tabGroup.open();
