Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.mirshahbazi:EventBus:V3.0.0'
	}

	dependencies {
		implementation("com.github.mirshahbazi:EventBus:V3.0.0")
	}

	<dependency>
	    <groupId>com.github.mirshahbazi</groupId>
	    <artifactId>EventBus</artifactId>
	    <version>V3.0.0</version>
	</dependency>


                            
    libraryDependencies += "com.github.mirshahbazi" % "EventBus" % "V3.0.0"


                            
    :dependencies [[com.github.mirshahbazi/EventBus "V3.0.0"]]

EventBus

EventBus is a publish/subscribe event bus optimized for Android.<br/> <img src="EventBus-Publish-Subscribe.png" width="500" height="187"/>

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

Define events:

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

Prepare subscribers: Declare and annotate your subscribing method, optionally specify a thread mode:

@Subscribe(threadMode = ThreadMode.MAIN)  
public void onMessageEvent(MessageEvent event) {/* Do something */};

Register and unregister your subscriber. For example on Android, activities and fragments should usually register according to their life cycle:

 @Override
 public void onStart() {
     super.onStart();
     EventBus.getDefault().register(this);
 }

 @Override
 public void onStop() {
     super.onStop();
     EventBus.getDefault().unregister(this);
 }

Post events:

 EventBus.getDefault().post(new MessageEvent());

Read the full getting started guide.

Add EventBus to your project

Via Gradle:

compile 'org.greenrobot:eventbus:3.0.0'

Via Maven:

<dependency>
    <groupId>org.greenrobot</groupId>
    <artifactId>eventbus</artifactId>
    <version>3.0.0</version>
</dependency>

Or download the latest JAR from Maven Central.
