Where do I download the ZXing library to add to my Android app?

[Ben Hutchinson]

I am interested in developing my own app that uses barcode scanning capability. I would like to use an AAR or JAR file (the easiest way to import a library for Android Studio) for a pre-compiled copy of the latest version of ZXing library. Where can I download such an AAR or JAR file? Can someone provide me with a link to that file?
