    The problem is that you have copied and pasted all of our android/ code into your project, and don’t really understand what you’ve copied. Copying our app this way is strongly discouraged. If you’re new to Android, it is probably too complex to try to reuse our code anyway.

    1. Remove all code you copied from android/ and core/
    2. Add android-integration/
    3. Implemented barcode scanning with 3 lines of code as per http://code.google.com/p/zxing/wiki/ScanningViaIntent
