Question

I am using barcodescanner.js to scan the qr code. I have the CaptureActivity android library downloaded and attached to my project

But when I call the following code

window.plugins.barcodeScanner.scan(scannerSuccess, scannerFailure);

Its giving me an error that

 Uncaught TypeError: Cannot read property 'barcodeScanner' of undefined at file:///android_asset/www/html/scan.html:83

It was working fine yesterday but giving me an error today. Any thoughts?

In the index.html, are you referencing the right javascript? In my case I had this:

<script type="text/javascript" charset="utf-8" src="phonegap-1.4.1.js"></script>

When I should have written this (cordova-xxx instead of phonegap-xxx):

<script type="text/javascript" charset="utf-8" src="cordova-1.7.0.js"></script>

Check in your assets folder and reference the right one. This solved my problem.
