This is a simple Rx Event Bus implementation using Kotlin. Includes small Android example project.
You should think twice though before using an event bus in project, it might create a complicated data flow in your app and a nightmare for debugging later. Also Rx is already providing you all event bus capabilities, but offer more control over data flow and scope.
//subscribe to events
Bus.observe<ExampleEvent>()
.subscribe { doSomething() }
.registerInBus(this) //registers your subscription to unsubscribe it properly later
//send events
Bus.send(ExampleEvent(someData))
//unsubscribe from events
Bus.unregister(this)
compile 'com.eightbitlab:rxbus:1.0.2'
