I'm trying to run the Text Recognition example https://www.b4x.com/android/forum/threads/b4x-textrecognition-based-on-mlkit.161210/ but get a Maven artifact not found: com.google.firebase/firebase-encoders error while compiling. I followed the instructions to search and download MLKit in the SDK manager and can see that firebase-encoders is installed but the example is not working for me. What is required to fix this and try the OCR example?
