Cordova not loading Architect World properly

Hello everyone!

I've just started using this SDK with cordova for Android (used as native android before) and i'm finding quite stressfull to get my architect world properly.

My guess is that the tracker is not working properly, but even at that I'm unsure where.

the app variable to push the plugin is identical to the example provided in the Startup guide.

The World variable I'm using is then identical to the "multiple targets" tutorial provided.

Surely the Javascript in some way is wrong, as there must be some difference between linking the two examples together. But where?

Can anyone please help me?

All the code is presented below (Logcat at the Bottom):

index.js (var app):

var app = {

// Url/Path to the augmented reality experience you would like to load
arExperienceUrl: "../index.html",
// The features your augmented reality experience requires, only define the ones you really need
requiredFeatures: ,
// Represents the device capability of launching augmented reality experiences with specific features
isDeviceSupported: false,
// Additional startup settings, for now the only setting available is camera_position (back|front)
startupConfiguration:
{
"camera_position": "back"
},
// Application Constructor
initialize: function() {
this.bindEvents();
},
// Bind Event Listeners
//
// Bind any events that are required on startup. Common events are:
// 'load', 'deviceready', 'offline', and 'online'.
bindEvents: function() {
document.addEventListener('deviceready', this.onDeviceReady, false);
},
// deviceready Event Handler
onDeviceReady: function() {
app.wikitudePlugin = cordova.require("com.wikitude.phonegap.WikitudePlugin.WikitudePlugin");
app.wikitudePlugin.isDeviceSupported(app.onDeviceSupported, app.onDeviceNotSupported, app.requiredFeatures);
},
// Callback if the device supports all required features
onDeviceSupported: function() {
app.wikitudePlugin.setOnUrlInvokeCallback(app.onURLInvoked);

app.wikitudePlugin.loadARchitectWorld(
app.onARExperienceLoadedSuccessful,
app.onARExperienceLoadError,
app.arExperienceUrl,
app.requiredFeatures,
app.startupConfiguration
);
},
// Callback if the device does not support all required features
onDeviceNotSupported: function(errorMessage) {
alert(errorMessage);
},
// Callback if your AR experience loaded successful
onARExperienceLoadedSuccessful: function(loadedURL) {
/* Respond to successful augmented reality experience loading if you need to */
},
// Callback if your AR experience did not load successful
onARExperienceLoadError: function(errorMessage) {
alert('Loading AR web view failed: ' + errorMessage);
}

};

app.initialize();

 

multipletargets.js (var world):

var World = {
loaded: false,

init: function initFn() {
this.createOverlays();
},

createOverlays: function createOverlaysFn() {
/*
First an AR.ClientTracker needs to be created in order to start the recognition engine. It is initialized with a URL specific to the target collection. Optional parameters are passed as object in the last argument. In this case a callback function for the onLoaded trigger is set. Once the tracker is fully loaded the function worldLoaded() is called.

Important: If you replace the tracker file with your own, make sure to change the target name accordingly.
Use a specific target name to respond only to a certain target or use a wildcard to respond to any or a certain group of targets.

Adding multiple targets to a target collection is straightforward. Simply follow our Target Management Tool documentation. Each target in the target collection is identified by its target name. By using this target name, it is possible to create an AR.Trackable2DObject for every target in the target collection.
*/
this.tracker = new AR.ClientTracker("assets/tracker.wtc", {
onLoaded: this.worldLoaded
});

/*
The next step is to create the augmentation. In this example an image resource is created and passed to the AR.ImageDrawable. A drawable is a visual component that can be connected to an IR target (AR.Trackable2DObject) or a geolocated object (AR.GeoObject). The AR.ImageDrawable is initialized by the image and its size. Optional parameters allow for position it relative to the recognized target.
*/

// Create overlay for page one
var imgOne = new AR.ImageResource("assets/imageOne.png");
var overlayOne = new AR.ImageDrawable(imgOne, 1, {
offsetX: -0.15,
offsetY: 0
});

/*
This combines everything by creating an AR.Trackable2DObject with the previously created tracker, the name of the image target as defined in the target collection and the drawable that should augment the recognized image.
Note that this time a specific target name is used to create a specific augmentation for that exact target.
*/
var pageOne = new AR.Trackable2DObject(this.tracker, "L", {
drawables: {
cam: overlayOne
}
});

/*
Similar to the first part, the image resource and the AR.ImageDrawable for the second overlay are created.
*/
var imgTwo = new AR.ImageResource("assets/imageTwo.png");
var overlayTwo = new AR.ImageDrawable(imgTwo, 0.5, {
offsetX: 0.12,
offsetY: -0.01
});

/*
The AR.Trackable2DObject for the second page uses the same tracker but with a different target name and the second overlay.
*/
var pageTwo = new AR.Trackable2DObject(this.tracker, "V", {
drawables: {
cam: overlayTwo
}
});
},

worldLoaded: function worldLoadedFn() {
var cssDivInstructions = " style='display: table-cell;vertical-align: middle; text-align: right; width: 50%; padding-right: 15px;'";
var cssDivSurfer = " style='display: table-cell;vertical-align: middle; text-align: left; padding-right: 15px; width: 38px'";
var cssDivBiker = " style='display: table-cell;vertical-align: middle; text-align: left; padding-right: 15px;'";
document.getElementById('loadingMessage').innerHTML =
"<div" + cssDivInstructions + ">Scan Target &#35;1 (surfer) or &#35;2 (biker):</div>" +
"<div" + cssDivSurfer + "><img src='assets/surfer.png'></img></div>" +
"<div" + cssDivBiker + "><img src='assets/bike.png'></img></div>";

// Remove Scan target message after 10 sec.
setTimeout(function() {
var e = document.getElementById('loadingMessage');
e.parentElement.removeChild(e);
}, 10000);
}
};

World.init();

Thank you very much for your help!!
I was indeed able to fix this error, and along with some indexing errors that I had for assets resolved, it's working beautifully.

Once again, thank you very much! :)
