EventBus 3.1.1

Hey, do have a minute for a [quick survey](https://docs.google.com/forms/d/e/1FAIpQLSePA8NqA9Jlbvh28xcFVbmIGUzHW3dnsxuxi23-ZDPPfkWMSQ/viewform) on how we are doing with EventBus? EventBus ======== EventBus is a publish/subscribe event bus for Android and Java.<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. [](https://travis-ci.org/greenrobot/EventBus) EventBus in 3 steps ------------------- 1. Define events: ```java public static class MessageEvent { /* Additional fields if needed */ } ``` 2. Prepare subscribers: Declare and annotate your subscribing method, optionally specify a [thread mode](http://greenrobot.org/eventbus/documentation/delivery-threads-threadmode/): ```java @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: ```java @Override public void onStart() { super.onStart(); EventBus.getDefault().register(this); } @Override public void onStop() { super.onStop(); EventBus.getDefault().unregister(this); } ``` 3. Post events: ```java EventBus.getDefault().post(new MessageEvent()); ``` Read the full [getting started guide](http://greenrobot.org/eventbus/documentation/how-to-get-started/). Add EventBus to your project ---------------------------- <a href="https://search.maven.org/#search%7Cga%7C1%7Cg%3A%22org.greenrobot%22%20AND%20a%3A%22eventbus%22"><img src="https://img.shields.io/maven-central/v/org.greenrobot/eventbus.svg"></a> Via Gradle: ```gradle compile 'org.greenrobot:eventbus:3.1.1' ``` Via Maven: ```xml <dependency> <groupId>org.greenrobot</groupId> <artifactId>eventbus</artifactId> <version>3.1.1</version> </dependency> ``` Or download [the latest JAR](https://search.maven.org/remote_content?g=org.greenrobot&a=eventbus&v=LATEST) from Maven Central.
