I've downloaded the library and the example.

- For some reason I needed to change "cast" with "cast1"
- And add: #MultiDex: True

It then compiled successfully

Thanks Erel, I don't have the same luck. I made the changes that you recommend, I even updated JAVA to version 14.

The truth is that now I get this error on the next line.

cast1.Initialize("Casty") '"4F8B3483" ' "E3AAA8CE")

Error occurred on line: 36 (Main)

[Erel]

This is not a compilation error. I'm not familiar with this library so can't help here. Sorry.
