How to add dependencies in google ocr?

Question

android studio

The guys need help, I use google ocr for real-time reading from the camera for my project, set it up as in the habr article https://habr.com/en/post/412679/ . My question is how can I add dependencies, I need to implement finding, for example, some combination of letters E304, for example, and so that everything stops or stands out and writes a brief description of this addition, sorry if it’s obvious how to do it, but I can’t add it.
