Hi everyone,I´m developing a final project Android app, where I´m using OpenCV, everything works fine until I´ve tried to detect and decod QR codes, I´ve been trying to understand how can I use this java code: https://docs.opencv.org/4.0.1/javadoc/index.html Can someone explain me how it works? or at least a working example in java about how to use it. Thanks so much and best regards.
