Phonegap barcodescanner encode function stops app

问题

I am using barcodescanner.js plugin in my phonegap app and everything is working great for the following code.

var scanner = cordova.require("cordova/plugin/BarcodeScanner");
  scanner.encode(scanner.Encode.TEXT_TYPE, 123456789, function(success) {
             alert("encode success: " + success);
           }, function(fail) {
             alert("encoding failed: " + fail);
           });

but having an issue when encode finishes app stops. Have anyone got any example code of creating an additional function to invoke the success callback. My requirement is to display barcode/QR code in the screen from saved phone text data.

I used my whole day searching for this. Found it on here: https://github.com/wildabeast/BarcodeScanner/issues/71

You need to search for menu/encode.xml in your file explorer from your project's root and replace it with: http://zxing.googlecode.com/svn/trunk/android/res/menu/encode.xml

If the link is ever unavailable, here is the code:

</menu>

Phonegap really needs a better community page and documentation.
