Can't start in fragmentet

[MiguelDAD]

Hello,

I'm trying to use your library following the README provided on your GitHub profile, but unfortunately, it's not working for me. I have also tried using the example you provided, but I still can't get it to work.

Additionally, I believe the steps to implement the library may be deprecated because I haven't been able to get it to work by following the first two steps. Could you please provide some assistance on how I can get the library to work properly?

Thank you for your time and help.
