I am using Phonegap with ngCordova and AngularJS. I am trying to use the following plugin (PhoneGap-Image-Resizer) to help me save some media to the device. My issue is that my plugin is giving me the following error:
[phonegap] [console.error] Error: undefined is not an object (evaluating '$window.imageResizer.getImageSize')
This only happens when i check the app on my device, when I run it locally through localhost:3000 I do not get the error. I get similar results when running a console log after the DeviceReady call. In the browser it is fine, where on the device it is undefined.
After a lot of research I have seen a few check the cordova.js file is being referenced in my index.html, which as you can see below it is:

Here is my partial
<div class="row collapse expanded text-center camera">
<div class="row">
<div class="small-12 columns end">
<canvas id="canvas" height="250" width="375"></canvas>
</div>
</div>
<div class="row">
<div class="small-12 columns">
<h2>Image of canvas</h2>
<img id="CanvasImage" alt="text" />
</div>
</div>
<div class="row">
<div class="small-6 columns">
<a class="button expanded" ng-click="camera()">Camera</a>
</div>
<div class="small-6 columns">
<a class="button expanded" ng-click="savecanvas()">savecanvas</a>
</div>
</div>
</div>
Here is my controller
angular.module('MyApp')
.controller('CameraCtrl', function($scope, $cordovaCamera, $rootScope, $location, $window, starFactory) {
$scope.savecanvas = function() {
document.addEventListener("deviceready", function() {
var theCanvas = document.getElementById('canvas');
var CanvasImage = document.getElementById('CanvasImage');
CanvasImage.src = theCanvas.toDataURL("image/png");
$window.imageResizer.storeImage(
function(data) { console.log('It worked!');},
function (error) {console.log("Error : \r\n" + error);},
theCanvas.toDataURL("image/png"),
{imageDataType: ImageResizer.IMAGE_DATA_TYPE_BASE64,format: ImageResizer.FORMAT_JPG}
);
}, false);
};
});
If anyone could please help me, understand why when i am on my device the plugins are undefined, when they work fine on the browser I will be very thankful.
This was a very tricky one to get my head around but we have finally got an answer. Phonegap uses Hydration, which is a way to update your application without having to reinstall it each time. Turns out there is a bug with Hydration in Phonegap 6.5.0 that means the cordova.js file is not loading properly. To solution to this is to Turn off Hydration. Once i turned that off, the plugins started to load on the device.
