I'm trying to use ngCordova for my cordova app however, I am getting device is undefined when calling the below:
var app = angular.module('app', ['ngCordova'])...
app.controller('homeController', function ($scope, $cordovaDevice) {
$scope.pageClass = 'page-home';
$cordovaDevice.getPlatform(); // console.log or something.
});
Everything is included correctly and the plugin is installed. What seems to be the problem?
You need to wait for the deviceready event before accessing any of the ngCordova plugins
document.addEventListener("deviceready", function () {
$cordovaDevice.getPlatform();
}, false);

I am working on mobile app using:
Ionic 2.1.4
Cordova 6.4.0
Angular 1.5.3
I've one view with external url using InAppBrowser plugin and I have a link in this website should redirect to certain view in my app
this issue is $location.url() not redirecting and not working at all, but when I tested the event I found it trigger normally.
here is my full code
angular.module('yogipass').controller('iframe',function ($location) {
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
console.log('here');
var ref=cordova.InAppBrowser.open('http://192.168.42.218/index.html', '_blank', 'location=no');
ref.addEventListener('loadstart', function(event) {
if (event.url.match("mobile/login")) {
console.log('worked!') // this logged normally
$location.url('/login');
ref.close();
}
});
}
])
You have to run digest cycle manually as you are changing location path from asynchronous event which is outside angular context.
Do wrap you code in $timeout function, which will fire up digest cycle. Apparently that will help to update location.
$timeout(function(){
$location.url('/login');
})
I'm developing a angular app, and this app has about a 10 configurable properties (depending on the environment and client).
I had those properties in json config files, but this is really troublesome: there must be specific builds per env/company. So I would like to retrieve those properties once from the backend on app load.
So in order to do this I created a Provider
var app = angular.module('myApp', [...]);
app.provider('environment', function() {
var self = this;
self.environment;
self.loadEnvironment = function (configuration, $http, $q) {
var def = $q.defer();
$http(...)
.success(function (data) {
self.environment = Environment.build(...);
def.resolve(self.environment);
}).error(function (err) {
...
});
return def.promise;
};
self.$get = function(configuration, $http, $q) {
if (!_.isUndefined(self.environment)) {
return $q.resolve(self.environment);
}
return self.loadEnvironment(configuration, $http, $q);
};
}
app.config(... 'environmentProvider', function(... environment) {
...
//The problem here is that I can't do environment.then(...) or something similar...
//Environment does exists though, with the available functions...
}
How to properly work with this Provider that executes a rest call to populate his environment variable?
Thanks in advance!
This is an excelent scenario to explore angularjs features.
Assuming that you really need the environment data loaded before the app loads, you can use angular tools to load the environment and then declare a value or a constant to store your environment configs before the app bootstraps.
So, instead of using ng-app to start your app, you must use angular.bootstrap to bootstrap it manually.
Observations: You mustn't use ng-app once you are bootstrapping the app manually, otherwise your app will load with the angular default system without respecting your environment loading. Also, make sure to bootstrap your application after declare all module components; i.e. declare all controllers, servieces, directives, etc. so then, you call angular.bootstrap
The below code implements the solution described previously:
(function() {
var App = angular.module("myApp", []);
// it will return a promisse of the $http request
function loadEnvironment () {
// loading angular injector to retrieve the $http service
var ngInjector = angular.injector(["ng"]);
var $http = ngInjector.get("$http");
return $http.get("/environment-x.json").then(function(response) {
// it could be a value as well
App.constant("environment ", response.data);
}, function(err) {
console.error("Error loading the application environment.", err)
});
}
// manually bootstrap the angularjs app in the root document
function bootstrapApplication() {
angular.element(document).ready(function() {
angular.bootstrap(document, ["myApp"]);
});
}
// load the environment and declare it to the app
// so then bootstraps the app starting the application
loadEnvironment().then(bootstrapApplication);
}());
I'm trying to use this plugin: csZbar
The problem is if i follow what is written in the github repository like this:
var app = angular.module('starter', ['ionic'])
app.controller("MainCtrl", function($scope){
$scope.newTask = function() {
cloudSky.ZBar.scan({}, function(succcess){
console.log(success);
}, function(error){
console.log(error);
})
};
});
the error log says:
ReferenceError: cloudSky is not defined
The csZbar is already included in the plugins folder.
I'm totally new to Ionic.
My problem was that I tried to run the app on desktop browser before run on ios.
It doesn't work if you simply run ionic serve, you must run it on ios itself.
I'm working on a mobile app using OnsenUI for the UI, running within the Monaca / Cordova framework, using Firebase as a BaaS through the angularfire module.
I've setup the module without Firebase as follows:
var myAppController = angular.module('myApp', ['onsen.directives']);
myAppController.controller('EventListCtrl', ['$scope', function($scope) {
However, as soon as I add Firebase as a module, the app stops working.
var myAppController = angular.module('myApp', ['onsen.directives', 'firebase']);
myAppController.controller('EventListCtrl', ['$scope', '$firebase', function($scope, $firebase) {
Can you please tell me what I'm doing wrong?
Thanks
According to this link, how about trying it this way:
var myAppController = angular.module('myApp', ['onsen.directives', 'firebase']);
myAppController.controller('EventListCtrl', function($scope, $firebase) {
Thought I should answer this myself to help anyone else facing the same situation.
My issue was that the firebase js script reference was wrong., ie. I was careless.

I am developing a mobile application using Cordova and AngularJS. How do I restrict bootstrapping of AngluarJS before Cordova device ready. Basically I don't want to use any of AngularJS controllers before device ready.
Manually bootstrap your Angular app:
Remove your ng-app attribute from your HTML code, so Angular doesn't start itself.
Add something like this to you JavaScript code:
document.addEventListener("deviceready", function() {
// retrieve the DOM element that had the ng-app attribute
var domElement = document.getElementById(...) / document.querySelector(...);
angular.bootstrap(domElement, ["angularAppName"]);
}, false);
Angular documentation for bootstrapping apps.
I'm using the following solution, which allows AngularJS to be bootstrapped when running with Cordova as well as when running directly in a browser, which is where much of my development takes place. You have to remove the ng-app directive from your main index.html page since that's what the manual bootstrapping is replacing.
UPDATE: I've since switched to the following method, which I think is cleaner. It works for Ionic as well as vanilla Cordova/PhoneGap. It should be the last bit of JavaScript to run - perhaps inside a script tag before the /body tag.
angular.element(document).ready(function () {
if (window.cordova) {
console.log("Running in Cordova, will bootstrap AngularJS once 'deviceready' event fires.");
document.addEventListener('deviceready', function () {
console.log("Deviceready event has fired, bootstrapping AngularJS.");
angular.bootstrap(document.body, ['app']);
}, false);
} else {
console.log("Running in browser, bootstrapping AngularJS now.");
angular.bootstrap(document.body, ['app']);
}
});
Here's the older solution I used:
// This is a function that bootstraps AngularJS, which is called from later code
function bootstrapAngular() {
console.log("Bootstrapping AngularJS");
// This assumes your app is named "app" and is on the body tag: <body ng-app="app">
// Change the selector from "body" to whatever you need
var domElement = document.querySelector('body');
// Change the application name from "app" if needed
angular.bootstrap(domElement, ['app']);
}
// This is my preferred Cordova detection method, as it doesn't require updating.
if (document.URL.indexOf( 'http://' ) === -1
&& document.URL.indexOf( 'https://' ) === -1) {
console.log("URL: Running in Cordova/PhoneGap");
document.addEventListener("deviceready", bootstrapAngular, false);
} else {
console.log("URL: Running in browser");
bootstrapAngular();
}
If you run into problems with the http/https detection method, due to, perhaps, loading a Cordova app into the phone from the web, you could use the following method instead:
function bootstrapAngular() {
console.log("Bootstrapping AngularJS");
// This assumes your app is named "app" and is on the body tag: <body ng-app="app">
// Change the selector from "body" to whatever you need
var domElement = document.querySelector('body');
// Change the application name from "app" if needed
angular.bootstrap(domElement, ['app']);
}
// This method of user agent detection also works, though it means you might have to maintain this UA list
if (navigator.userAgent.match(/(iOS|iPhone|iPod|iPad|Android|BlackBerry)/)) {
console.log("UA: Running in Cordova/PhoneGap");
document.addEventListener("deviceready", bootstrapAngular, false);
} else {
console.log("UA: Running in browser");
bootstrapAngular();
}
Note that you still need the same bootstrapAngular function from the first example.
Why manually bootstrap AngularJS with Cordova/PhoneGap/Ionic?
Some people getting here might not know why you would want to do this in the first place. The issue is that you could have AngularJS code that relies on Cordova/PhoneGap/Ionic plugins, and those plugins won't be ready until after AngularJS has started because Cordova takes longer to get up and running on a device than the plain old Javascript code for AngularJS does.
So in those cases we have to wait until Cordova/PhoneGap/Ionic is ready before starting up (bootstrapping) AngularJS so that Angular will have everything it needs to run.
For example, say you are using the NG-Persist Angular module, which makes use of local storage for saving data on a browser, iOS Keychain plugin when running on iOS, and the cordova-plugin-file when running on Android. If your Angular app tries to load/save something right off the bat, NG-Persist's check on window.device.platform (from the device plugin) will fail because the mobile code hasn't completed startup yet, and you'll get nothing but a white page instead of your pretty app.
If you are using Ionic, this solution works for browsers and devices. Credit to romgar on this thread.
window.ionic.Platform.ready(function() {
angular.bootstrap(document, ['<your_main_app']);
});
Still need to remove ng-app from your DOM element.
This solution became more robust when I used:
angular.element(document).ready(function () {
var domElement = document.getElementById('appElement');
angular.bootstrap(domElement, ["angularAppName"]);
});
UPDATE
My suggestion was to put the above within the appropriate deviceready function, e.g.:
document.addEventListener("deviceready", function() {
angular.element(document).ready(function () {
var domElement = document.getElementById('appElement');
angular.bootstrap(domElement, ["angularAppName"]);
});
}, false);
On using the solution from TheHippo:
document.addEventListener("deviceready", function() {
// retrieve the DOM element that had the ng-app attribute
var domElement = document.getElementById(...) / document.querySelector(...);
angular.bootstrap(domElement, ["angularAppName"]);
}, false);
It doesn't work in the browser because "cordova.js" gets resolved by the Cordova or Phonegap building process and is not available in your localhost or emulated testing environment.
Thus the "deviceready" event is never fired. You can simply fire it manually in your browsers console.
var customDeviceReadyEvent = new Event('deviceready');
document.dispatchEvent(customDeviceReadyEvent);
Also make sure, that the bootstrap of angular gets triggered after setting all of you angular modules/controllers/factories/directives etc.
In most cases you probably don't need to block loading your angular app until after deviceready (mind that it can take several seconds for deviceready to fire if you have a lot of plugins).
Instead you can use something like this lib (https://github.com/arnesson/angular-cordova) which solves the deviceready issues for you by automatically buffering calls and then execute them after deviceready has been fired.
