.run(function($ionicPlatform, $rootScope, $cookieStore, $state) {
$ionicPlatform.ready(function() {
// Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
// for form inputs)
if (window.cordova && window.cordova.plugins.Keyboard) {
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
cordova.plugins.Keyboard.disableScroll(true);
}
if (window.StatusBar) {
// org.apache.cordova.statusbar required
StatusBar.styleDefault();
}
});

// Check login session
$rootScope.$on('$stateChangeStart', function(event, next, current) {
    var userInfo = $cookieStore.get('userInfo');

    if (!userInfo) 
    {
        // user not logged in | redirect to login
        if (next.name !== "welcome") 
        {
            // not going to #welcome, we should redirect now
            event.preventDefault();
            $state.go('welcome');
        }
    }
