EventBus is a publish/subscribe event bus optimized for Android.

EventBus...

• simplifies the communication between components
  • decouples event senders and receivers
  • performs well with Activities, Fragments, and background threads
  • avoids complex and error-prone dependencies and life cycle issues
• makes your code simpler
• is fast
• is tiny (~50k jar)
• is proven in practice by apps with 100,000,000+ installs

• has advanced features like delivery threads, subscriber priorities, etc.

  

EventBus in 3 steps

1. Define events:

   public class MessageEvent { /* Additional fields if needed */ }

2. Prepare subscribers: Register your subscriber (in your onCreate or in a constructor):

   eventBus.register(this);

   Declare your subscribing method:

   @Subscribe  
   public void onEvent(AnyEventType event) {/* Do something */};

3. Post events:

   eventBus.post(event);

This getting started guide shows these 3 steps in more detail.
