How to pass data Activity to Activity in Android use Event Bus otto

Today I use a method of  pass data in android eventbus Otto, to perform sending data from Activity to Activity in Android, here are the steps to send data in Android.

Step 1. Creat clss EventBus.class

package com.example.eventbus.model;
import com.squareup.otto.Bus;
public class EventBus {
    private static Bus sBus;
    public static Bus getBus() {
        if (sBus == null)
            sBus = new Bus();        return sBus;    }
}

Step 2. Create event mesage

package com.example.eventbus.model;
public class MessageEvent {
    public String mMessage;
    public MessageEvent(String message) {
        mMessage = message;    }

    public String getMessage() {
        return mMessage;    }
}

Step 3. Create layout activity_main.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    tools:context=".MainActivity">    <Button        android:id="@+id/btn_click"        android:text="Second"        android:layout_width="match_parent"        android:layout_height="wrap_content" />
    <TextView        android:id="@+id/tv_message"        android:layout_marginTop="20dp"        android:padding="10dp"        android:textColor="#000"        android:textSize="20dp"        android:layout_width="match_parent"        android:layout_height="wrap_content" />
</LinearLayout>

Step 4. Create second_acitivity.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical" android:layout_width="match_parent"    android:layout_height="match_parent">    <Button        android:id="@+id/btnSendData"        android:layout_width="match_parent"        android:text="Send"        android:layout_height="wrap_content" />
</LinearLayout>

Step 5. Register Event in MainActivity

EventBus.getBus().register(this);

@Overrideprotected void onStop() {
    super.onStop();    EventBus.getBus().unregister(this);}

Step 7. Regiter and listnengEvent in SecondActivity.xml

    public void getMessage(MessageEvent event) {
        Toast.makeText(this, "" + event.getMessage(), Toast.LENGTH_SHORT).show();

        super.onStart();
        EventBus.getBus().register(this);
