Error: Property 'barcodeScanner' is not readable

Currently, I am utilizing barcodescanner.js for scanning QR codes. I have successfully downloaded and linked the CaptureActivity android library to my project.

However, when attempting to execute the following code:

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

An error is being generated that states:

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

Oddly enough, this functionality was operational yesterday but seems to be encountering issues today. Any insights into potential resolutions?

Answer №1

Double-check the index.html file to ensure you are pointing to the correct JavaScript library. My experience led me to discover:

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

The correct reference should be (using cordova instead of phonegap):

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

Make sure to confirm in your assets folder that you have chosen the right one. Following this adjustment, I was able to resolve my issue.
