        backgroundColor:'black',
        navBarHidden: false,

var actionBar;
win.addEventListener("open", function() {
    if (Ti.Platform.osname === "android") {
        if (! win.activity) {
            Ti.API.error("Can't access action bar on a lightweight window.");
            alert("NOT ACTIVITY");
        } else {
            actionBar = win.activity.actionBar;
            if (actionBar) {
                alert("ACTIVITY");
                actionBar.backgroundImage = "/images/bg_top.png";
                actionBar.title = "New Title";
                actionBar.onHomeIconItemSelected = function() {
                    Ti.API.info("Home icon clicked!");
                };
            }
        }
    }
});

try wrapping it in onCreateOptionsMenu

   win.activity.onCreateOptionsMenu = function(e) {
        actionBar = win.activity.actionBar;
        if (actionBar) {
            alert("ACTIVITY");
            actionBar.backgroundImage = "/images/bg_top.png";
            actionBar.title = "New Title";
            actionBar.onHomeIconItemSelected = function() {
                Ti.API.info("Home icon clicked!");
            };
        } else {
            alert('missing action bar');
        }
     });
