Deploying custom business logic

I had to assign various roles to users while registering,so I used the custom business logic yo create a code which gave me a zip file of code with after register event.
But I don’t know how to add this generated code to my android project files.
Thank you

@Christie v thoma,

CBL project comes as separate project, you need to unpack the zip to separate folder from your Android app and open it as project with your favorite IDE.
