What is the preferred way to embed the zxing library to provide scanning without having the Barcode Scanner app installed? I am looking to embed it in android without having to prompt the user for any extra installs. (Similar to the way the iPhone src works).
It's really easier to just integrate via Intent. More reliable, and you get updates automatically. While I don't advise it...
The complete source code is available from the ZXing project. You want to build
core/ and put it in your Android
lib/ folder to include the core decoder in your app. You do not want to include
javase. You can look to the code in
android/ as it is the source to Barcode Scanner, but as the authors we'd suggest you not just copy and paste it.
It is Apache licensed which means you can use it freely, as long as you essentially give the user access to the license terms.
