I tried to create 3-view app without using the Ionic menu component. So i modified my previous app with sidebar menu by this way:
app.js
.run(function($ionicPlatform, $rootScope) {
$ionicPlatform.ready(function() {
// Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
// for form inputs)
if(window.cordova && window.cordova.plugins.Keyboard) {
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
}
if(window.StatusBar) {
StatusBar.styleDefault();
}
// PROXIMITY SENSOR
function onSuccess(state) {
console.log('Proximity state: ' + (state ? 'near' : 'far'));
};
if(navigator.proximity != null)
{
navigator.proximity.enableSensor();
setInterval(function(){
navigator.proximity.getProximityState(onSuccess);
}, 100);
}
// END PROXIMITY SENSOR
});
})
.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('app', {
url: '/home',
templateUrl: 'templates/home.html',
controller: 'HomeCtrl'
})
.state('app.game', {
url: '/game',
templateUrl: 'templates/game.html',
controller: 'GameCtrl'
})
.state('app.about', {
url: '/about',
templateUrl: 'templates/about_app.html'
});
// if none of the above states are matched, use this as the fallback
$urlRouterProvider.otherwise('/app/home');
});
From example above is app/home is default state but if i started app no content of template templates/home.html is displayed and controller seems to be not initialized and only content which is visible is text defined in index.html file..
index.html
<!DOCTYPE html>
<html>

<script src="js/controllers/game.js"></script>
</head>
<body ng-app="starter">
TEST LINK
</body>
</html>
Console output in Chrome gives me no error, but content of the template file and manually redirection to another URL is not working.
What i'm doing wrong please?
Many thanks for any advice.

Sorry if my previous answer wasn't clear.
The way i understand in ionic, view hierarchy root element is
<ion-nav-view></ion-nav-view>
either add it into body of index.html or create a route state with for url:'/' with inline template.
Solution is following:
.config(function($stateProvider, $urlRouterProvider) {
$stateProvider
.state('game', {
url: "/game",
templateUrl: "templates/game.html",
})
.state('home', {
url: "/home",
templateUrl: "templates/home.html",
controller: "HomeCtrl"
})
// if none of the above states are matched, use this as the fallback
$urlRouterProvider.otherwise('/home');
});

I'm using ui router and angular js so when I test the app, I just get a blank screen with an injector:module error. This is the link to the error:
http://errors.angularjs.org/1.3.11/$injector/modulerr?p0=myApp&p1=Error%3A%…dflare.com%2Fajax%2Flibs%2Fangular.js%2F1.3.11%2Fangular.min.js%3A17%3A350
Here is my app.js code:
var app = angular.module('myApp', ['ui.router', 'firebase']);
// Creating fireref instance
app.factory('FireRef', function($firebase){
var ref = new Firebase('https://dablog.firebaseio.com/');
return ref;
});
// Creating fireauth instance
app.factory('FireAuth', function($firebaseAuth){
var ref = new Firebase('https://dablog.firebaseio.com/');
return $firebaseAuth(ref);
});
app.config(function($stateProvider, $urlRouterProvider){
$urlRouterProvider.otherwise('/site/home');
$stateProvider
.state('site', {
url: '/site',
templateUrl: 'partials/site.html'
})
.state('site.home', {
url: '/home',
templateUrl: 'partials/home.html'
})
.state('site.about', {
url: '/about',
templateUrl: 'partials/about.html'
})
.state('site.projects', {

})
.state('site', {
url: '/contact',
templateUrl: 'partials/contact.html'
});
})
Here is my blog.js file where it says "app is not defined":
'use strict'
app.controller('BlogCtrl', function($scope, $firebase, $firebaseArray, FireRef, $state){
var data = $firebaseArray(FireRef);
$scope.posts = data;
$scope.$watch('posts', function(newValue, oldValue){
$scope.posts = $sce.trustAsHtml(data);
})
$scope.login = function() {
$state.go('site.login');
}
$scope.newPost = function(){
$state.go('site.newPost');
}
});

You have declared 'use strict', so the app variable is undefined. You need to add
var app = angular.module('myApp');
to the top of BlogCtrl.js
Also, move <script src="js/app.js"></script> so that it's before the controller scripts in index.html. Because you load app.js after BlogCtrl.js, the module defined in app.js is not available in BlogCtrl.js.
I don't have enough reputation to comment, but I do want to add information: do not add var app = angular.module('myApp', []) in blog.js, because the brackets initialize a new app, so Angular will think you're creating a new app and will throw an error, since 'myApp' already exists. Be sure to use var app = angular.module('myApp') instead. Also be sure to link the the .js file in your index file after Angular has been loaded.
I think you need to include this line at the top of blog.js:
var app = angular.module('myApp');
Edited to remove the second parameter: , [].

Question:
If i use $cookieStore it works on browser without any problem.
However when i publish project to phone $cookieStore is not working. I mean When i try to use $cookieStore in android phone.
$cookieStore displays below error on $ionicPopup.alert.
undefined
How can i use cookie on android by using ionic?
Any help will be appreciated.
Thanks.
Instead of using $cookieStore which doesn't seem to play nicely on Android, simply replace it with the default localStorage. It works just fine! :)
$cookieStore.set() -> window.localStorage.setItem()
$cookieStore.get() -> window.localStorage.getItem()
$cookieStore.remove() -> window.localStorage.removeItem()
Please vote up this answer instead as I wasn't logged in properly on the other one when I posted >_< doh!

I am working on ng-Cordova to build a project. I tried so many examples to get logging with google. My need is to login to my app using google account. I have login button. When I click the button, it needs to redirect to google account and sign in with the google account and need to come back to my app.
I have a google client id. I hereby post my index.html file and app.js file.

When I run the app, only Index file with blank page is showing. I don't know what is the problem. Can somebody help me?
Hi in github i uploaded a sample project to login via google before you execute the project please follow the steps in README.md file of github
I am new to Angular and learned the basics about it recently.
In my current project, I am developing a single page application. As of now, my HTML/JS setup is as per below:
HTML:
<body>
<ng-include src='"src/includes/home.html"'></ng-include>
<!-- home.html is the HTML template with static data -->
</body>
app.js:
'use strict';
var app = angular.module('MyApp',['home']);
angular
.module('home', [])
.directive('homeDir', function(){
return {
replace: true,
restrict: 'E',
templateUrl: 'src/includes/home.html'
};
});
This code is working fine but I would like to introduce routing to have better control over the pages, instead of using ng-include.
So now, my HTML looks the same and I actually dont know what to change in it while using routing.
My app.js now looks like this:
'use strict';
var app = angular.module('MyApp',['home']);
// trying to introduce routing:
angular
.module('home', ['ngResource', 'ngRoute'])
.config(['$routeProvider', '$locationProvider'],
function($routeProvider, $locationProvider){
$routeProvider.
when('/', {
templateUrl: 'src/includes/home.html',
controller: 'homeCtrl'
}).
when('/drawer', {
redirectTo: 'src/includes/home.html#drawer',
controller: 'drawerCtrl'
})
.otherwise({
redirectTo: '/'
});
// use the HTML5 History API
$locationProvider.html5Mode(true);
}
);
app.controller('homeCtrl', function($scope){
$scope.message = "some message";
console.log("homeCtrl called");
});
app.controller('drawerCtrl', function($scope){
$scope.message = "some other message";
console.log("drawerCtrl called");
});
However, I am getting an error:
Error: error:modulerr
Module Error
As per the link following the error:
This error occurs when a module fails to load due to some exception.
Why is it not loading? What am I missing? What should I change the HTML to?
UPDATE:
After including angular-route.min.js, I am getting the error:
Error: whole is undefined

Config section is incorrect. Instead of
.config(['$routeProvider', '$locationProvider'], function($routeProvider, $locationProvider) { ... });
it should be
.config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider) { ... }]);
Note, that function definition belongs to array object.
Another mistake is in redirectTo property of the drawer route, currently it doesn't make sense. You want probably this instead:
.when('/drawer', {
templateUrl: 'src/includes/drawer.html',
controller: 'drawerCtrl'
})
Ensue that you have added the angular-route.js file to the html file.
And you are missing the ngRoute module here -
var app = angular.module('MyApp',['ngRoute','ngResource' ]);
app.config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider){... }]);
dfsq is correct. There are syntax errors in the code.
I'm new to AngularJS. I've following egghead.io I've set up a controller and model to retrieve message from input component and display it. I'm using ui-router.
Here's my index.html
<!DOCTYPE html>
<html ng-app="app">
<head lang="en">
<meta charset="UTF-8">
<title> </title>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.4.3/angular.js"></script>

<script src="app.js"></script>
</head>
<body>
<div ui-view=""></div>
</body>
</html>
Here's my app.js
angular.module('app',["ui.router"])
.config([function($stateProvider) {
$stateProvider
.state('index', {
url:"",
templateUrl:"templates/first.html",
controller:"FirstCtr as first"
});
});
.controller("FirstCtr", function FirstCtr() {
var first = this;
first.greeting = "First";
});
Here's my templates/first.html
<input type="text" ng-model="first.greeting"/>
<div ng-class="first.greeting">
{{first.greeting}} {{"World"}}
</div>
After I go to http://localhost:8080, it was blank and throw this error
Please give me some suggestions.
Your state definition should be be declared controller alias in controllerAs option of state, with it you need to remove the semicolon from config block end.
Also you need to inject $stateProvider dependency properly to avoid error.
Code
angular.module('app', ["ui.router"])
//missed `'$stateProvider'` dependency here
.config(['$stateProvider', function($stateProvider) {
$stateProvider
.state('index', {
url: "",
templateUrl: "templates/first.html",
controller: "FirstCtr",
controllerAs: "first"
});
}]) //remove semicolon from here as you are appending app in chain
.controller("FirstCtr", function FirstCtr() {
var first = this;
first.greeting = "First";
});
