I was just trying out the newest version of PhraseMeme Scanner that uses Mango for automated barcode capture.
Now that this is released do you plan to add this to the project's source?
Otherwise, I think I can infer what you're doing but feel free to correct me. It seems like you are calling Focus() on the camera every 2 seconds or so and then sending the result of one the GetPreviewBuffer methods into the ZXing library. I haven't looked
enough at the library to know which of those preview methods is needed but hopefully that didn't cause you too many issues.
It'd be great to hear about how you extended the functionality for Mango. Its a great app!
