Installing Phonegap/Cordova 3.1 plugins (barcodescanner)

Question

Been trying this for a few hours now and have made a little progress but not in the right direction.

I have successfully setup an Android Cordova project which loads onto a phone and runs fine. I just cannot get the barcode scanner plugin to work in Cordova 3.1. I believe it has installed correctly but it does not appear in the config.xml, it does however appear in the cordova_plugins.js file etc.

I have this in my index.js

function clickScan() {
    var scanner = cordova.require("com.phonegap.plugins.barcodescanner.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);
        }
   );
}

Now when I press the scan button it seems to run this code but jumps straight to the success function and just displays the alert box with blank results.

The scanner I am using and have installed via cordova plugin add is https://github.com/wildabeast/BarcodeScanner

I am not currently importing the barcodescanner.js file into the html as I have done with older versions of cordova as I believe this is handled differently in 3+ and seems to be defined in the cordova_plugins.js file?

Update : As far as I am aware with the config above there does not seem to be any glaring errors popup in Eclipse.

Yes, You dont need to import any plugin specific javascript file in your index.html. Just Verify that plugin in properly installed in your project by confirming YourProject/res/config.xml file has the following entry:

<feature name="BarcodeScanner">
    <param name="android-package" value="com.phonegap.plugins.barcodescanner.BarcodeScanner" />
</feature>

For using the plugin, just use the updated syntax of calling the plugin functions -

function clickScan() {
cordova.plugins.barcodeScanner.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);
  });}
