A handful of pseudocode is left in there as well. A quick snippet is demonstrated below for handling a Qr-code. This would be the component that I would suggest going forward with recognition. It allows for quick integration with the camera APIs and extracts the information with simplicity. The detection library that Google has provided within the past year has been a much easier library to work with. If this indeed does provide a nice way to get at this information (without jumping through hoops and complications), then I'll update with the source and check this off as an accepted answer. At the moment, I wanted to update my answer for this official release. I'll repost with some sample code for achieving these results from a captured image. The inclusion of these libraries will make for a smooth integration. The barcode detection library is described here. While Sean Owen and others that have worked on the original Zxing library had provided an approach to work with the barcode libraries for the past several years, Google has finally put out an official release with Google Play Services for handling qr and barcodes. As developers we should have access to a library capable of extracting a QRCode from an image or frame that we can then remove encoded data from. It actually puzzles me as to why there hasn't been native implementations of the QRCode functionality added into perhaps the Camera library or similar place within the Google SDK natively within the operating system.Ĭalling and requiring another application (or even requesting a download) is not an elegant solution and no users should be succumbed to doing such thing. I hadn't seen examples or individuals speaking of it in this manner. It should scan images from the Camera2 API in a very simplistic manner. I thought I might ask the community once more what the other options might be for a QR code library that does not launch an activity and call outside our own applications. Several others have been asking for QRCode scanning alternatives and I have not seen useful feedback. While there have been plenty of posts thus far referencing the ZXing library for QRCode scanning, I haven't found that to be a solution that works for me. What do we have out there available to us (if anything) that we can call for QR data discovery and extraction on an image?
