I have the same error and my project is stuck, any solution or similar package ?

RonRadtke commented

But this is likely to the fact that I'm heavily using native code written in java and the lib not being part of the Expo SDK. So you can't use it.

Are you planning to make this module work with expo or do you know any substitute for you package which works on expo?
