• Create a project on the firebase console : https://console.firebase.google.com/

• Enter your app's package name

• Donwload the json file provided and insert into the "app" folder in your android project

• Then add this inside dependencies on your root level build.gradle

• classpath 'com.google.gms:google-services:3.0.0'

• And this at the bottom of the app level build.gradle

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

• Inside the same file but under "dependencies" you put this

compile 'com.google.firebase:firebase-core:9.2.1'

• Declare a "FirebaseAnalytics" object on top of your MainActivity and the onCreate initialize it

• mFirebaseAnalytics = FirebaseAnalytics.getInstance(this);

Bundle bundle = new Bundle();
bundle.putString(FirebaseAnalytics.Param.ITEM_NAME, name);
mFirebaseAnalytics.logEvent(FirebaseAnalytics.Event.SELECT_CONTENT, bundle);
