phonegap 3.1 BarcodeScanner uncaught module cordova/plugin/BarcodeScanner not found - plugins

Question

I'm new on Phonegap and JS... and I tried it with a barcode scanner... I installed the phonegap and everything with this tutorial http://teusink.blogspot.com/2013/07/guide-phonegap-3-android-windows.html
I installed the BarcodeScanner from CMD and exported the project as android platform...
Add it to Eclipse ... followed all the tutorials how to do it, added all permissions and stuff..
when i try the app on ma samsung tab2 ... the app comes up but when i click the "scan" link i get the error uncaught module cordova/plugin/BarcodeScanner not found in the logcat.
this is the call <a href="#" class="btn large" onclick="scaning();">Scan</a
i have this in the index html head
<script src="phonegap.js"></script>
<script src="barcodescanner.js"></script>
this is the scaning function
function scaning(){
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);
}
);};
and this is in the config.xml
<feature name="BarcodeScanner">
<param name="android-package" value="com.phonegap.plugins.barcodescanner.BarcodeScanner" />
</feature>
I think I checked the whole Google for the answer ... but till now nothing worked... and still for the phonegap 3.0+ version there is almost none documentation for the barcode scanner ... at least for a beginner ...
if you can help me guys .... couse I'm totally lost :S

Answer 1

Although I've never used older versions as I'm quite new into Phonegap/Cordova, Version 3.1 seems to use a slightly different approach for accessing plugins. Following worked for me with Cordova 3.1 and BarcodeScanner.
Install plugin with
plugman install --platform android --project=DIR-TO-CORDOVA-PROJECT --plugin=https://github.com/wildabeast/BarcodeScanner
You don't have to reference barcodescanner.js by your own, cordova takes care of the includes - the example code from https://github.com/wildabeast/BarcodeDemo worked except I had to change the plugin path from
var scanner = cordova.require("cordova/plugin/BarcodeScanner");
to
var scanner = cordova.require("com.phonegap.plugins.barcodescanner.BarcodeScanner");

Answer 2

edit the file: js/index.js
find the code: var scanner = cordova.require("cordova/plugin/BarcodeScanner");
replace "cordova/plugin/BarcodeScanner"
to "com.phonegap.plugins.barcodescanner.BarcodeScanner"

Answer 3

This one worked for me:
var scanner = cordova.plugins.barcodeScanner;

Answer 4

Had the same problem , got fixed by installing it via plugman like this
plugman install --platform android --project=DIR-TO-CORDOVA-PROJECT --plugin=https://github.com/wildabeast/BarcodeScanner
where DIR-TO-CORDOVA-PROJECT is E:/ProjectName/platform/android
If I didn't add the /platform/android it gave an error
and then put this in the scanning() function
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);
}
);
