        public void onTabUnselected(android.app.ActionBar.Tab tab,
                FragmentTransaction ft) {
            // TODO Auto-generated method stub

        }};
        //Add New Tab
        actionBar.addTab(actionBar.newTab().setText("Android").setTabListener(tabListener));
        actionBar.addTab(actionBar.newTab().setText("iOS").setTabListener(tabListener));
        actionBar.addTab(actionBar.newTab().setText("Windows").setTabListener(tabListener));
