EventBus is subscribed/publish event bus to communication between components with limited lines of code, in short, its bus for events transfers the data between one activity(class) to another to reflect the changes based on our needs. That makes the data exchange between components like Activity, Fragment, Services, and any kind of backgrounds threads pretty easy.
