Hi Steve...

I did come across those links and it seems like it has something to do with the versions of cordova.js in the project, but Icenium inserts both android and ios versions of the cordova.js files when you create the project so I assume it's inserting the correct versions of the files.

Downloaded your barcodescanner sample app and tried to emulate that in my application structure but I'm still having this issue. I even copied the code within both the cordova.js files in the barcodescanner sample and put it into the files in my app but no change.

It only happens when the app is deployed to a device or run on the device through Icenium. It works perfectly in the Icenium simulator.

I've attached my index.html and index.js files for your consideration.

Regards,
Devon Britton.

Hello Devon,

According to those articles, this problem was specific to an earlier version of Cordova and yes, when you create a new Icenium project, we insert the correct versions of Cordova depending on your target version (min version is Cordova 2.0). The Bardcode scanner sample works correctly with Cordova 2.x version and we do not get any errors on the tested devices. Do you run the demo as it is without any modifications? What is the target Cordova version, device model and OS version?

You are quite welcome to give me the moron of the week award...

I had another cordova.js file in my scripts folder and I was referencing that one instead of the one created when I created the project in Icenium.

I'm still having a problem getting the barcodescanner to work however.

I've tried the following 2 code segments and neither of them works. Nothing happens in the deployed app.

I put an following alert in the second code segment - alert(window.plugins.barcodeScanner) and it returned "undefined".

I am referencing my <script src="scripts/barcodescanner.js"></script> in my index.html page.

function captureBarcode()
        {
            var scanner = cordova.require("cordova/plugin/BarcodeScanner");
            scanner.scan(
            function (result)
            {
                alert("We got a barcode\n" +
                "Result: " + result.text + "\n" +
                "Format: " + result.format + "\n" +
                "Cancelled: " + result.cancelled);
            },
            function (error)
            {
                alert("Scanning failed: " + error);
            });
        }

function captureBarcode()
        {
        alert("Capture Barcode - Index");
            window.plugins.barcodeScanner.scan(
           function(result)
            {
               if (!result.cancelled)
                {
                   that._addMessageToLog(result.format + " | " + result.text);
               }
           },
           function(error)
            {
               console.log("Scanning failed: " + error);
           });

            function addMessageToLog(message)
             {
                var that = this,
                currentMessage = that.resultsField.innerHTML;
                that.resultsField.innerHTML = currentMessage + message + '<br />';
             }
        }

My project is available here if for your consideration...

Hi Steven.

Yes the barcodescanner sample app runs perfectly well when I follow that sequence. My application also runs when I simulate it on the device, but nothing happens when I press the scan button.

I am building my app using phonegap build and both the deployed app buiklt through phonegap build AND my app when run on the device through Icenium behave in exactly the same manner so I don't think the issue is with the build process.

As I say I am at a complete loss as to what is happening. I've tried everything. My code is here (http://sdrv.ms/18BFKve) and I would REALLY appreciate it if you could take a look and see if you can see what's wrong??

Thanks so much!!
