first you should dig into some research and then ask question.

But AFAIK firebase lacks documentation. So I will try to explain steps to it.

read firebase documentation, and use updated Method from here

  1. First of all go to firebase Console and create a project(give it name and location)

  2. If you want to read write data without Authentication steps then change rules in firebase console like

    {
   "rules": 
   {
      ".read": true,
      ".write": true
   }
}

  3. If you want to add firebase manually. Go to project settings and select android. give packageName , where name and SHA-1 is optional. download google-service.json and in android studio change it's view to Project and paste it under app folder.

  4. Add below dependency to project build.gradle 

    dependencies {
      classpath 'com.android.tools.build:gradle:2.1.3'
      classpath 'com.google.gms:google-services:3.1.0'
}

    and at app Level build.gradle.

    dependencies {       
     compile 'com.google.firebase:firebase-database:9.4.0'
}

    //add it at the bottom of app level build.gradle

    apply plugin: 'com.google.gms.google-services'

  5. Add internet permission in Manifest

  6. and to set data to firebase Use

        FirebaseDatabase database = FirebaseDatabase.getInstance();
    DatabaseReference myRef = database.getReference("rootNode "); // yourwebisteurl/rootNode if it exist otherwise don't pass any string to it.

    myRef.setValue("Hello, World!");

    or 

       DatabaseReference database = 
   FirebaseDatabase.getInstance().getReference();
   DatabaseReference ref = database.child("rootNode");//if rootNode exist
   database.setValue("TestRefValue");

Note

i. Upgrade Google Play Services and Google Repository

The Firebase documentation is a good place to start, but if you need tutorials to get started with Firebase I recommend the Firebase essentials course from Udacity and Google :

https://www.udacity.com/course/firebase-essentials-for-android--ud009

It's free and there's two major course content updates coming soon.
