Here are two possibilities: 1. You store on the phone the barcode as an alphanumeric value and a bar code type, then generate the image on the phone. That would require a bar code imaging JAR, and while those probably exist for Java, I expect they may require some massaging to work on Android. 2. You store on the phone the actual barcode image, obtained from a Web service or something. This has the advantage of being a better-traveled road. Then, you'd just use an ImageView, or the 2D graphics API, to display the image on screen. The only thing I see potentially being tricky with scenario #2 is getting the image size right, taking into account different screen densities. And, you have that same problem with scenario #1. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy _Android Programming Tutorials_ Version 1.0 In Print! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
