BarcodeScanner
|
||||
==============
|
||||
|
||||
Added version that runs with windows mobile devices.
|
||||
To run on those devices, the zxing.net library must be added to the project (Install as nuget packet - more information on http://www.nuget.org/packages/ZXing.Net)

Windows Phone currently only supports Scaning for codes, feel free to extend it that it can also encode.

Cross-platform BarcodeScanner for Cordova / PhoneGap.

This plugin leverages Cordova/PhoneGap's [require/define functionality used for plugins](http://simonmacdonald.blogspot.ca/2012/08/so-you-wanna-write-phonegap-200-android.html).
|
||||
|
||||
Note: the Android source for this project includes an Android Library Project.

plugman currently doesn't support Library Project refs, so its been
