@wasabeef @pgreze , could you please review whether this is a good addition for the list?

@alexandrehtrb thank you for adding this new library.
I think there's several other improvements that should be done before merging it:

1. jcenter will be closed soon. At least for new projects, they should use a more future-proof publication channels (like Maven Central)
2. default README is not in English. I would advise to use it as the default language before pushing it in this EN first library collection.

Hello @pgreze ,

I took care of the improvements you mentioned!
The library is now available on Maven Central and the default README is in english.
