Firebase Analytics - It is another feature of Firebase. It is a powerful tool that tracks how user your app.

Analytics provides you with unlimited reporting for up to 500 distinct events that you can define using the firebase SDK.Firebase Analytics reports you understand clearly how your user behave, which enables you to make informed decisions regarding app marketing and performance optimizations.

Creating Firebase Project

 1) First got to https://firebase.google.com/  and  click "GET STARTED FOR FREE" make an                  account and create your first project.

 2) After creating account it redirects you to firebase console. click on "Add Project". A dialog will          open and enter project name and country. click on "Create Project".

3) After creating project, it redirect to firebase console page and click there on "Add firebase to your       android app"

4) Here enter the package name of firebase app and you can also enter the nickname and SHA1 but it     is not compulsory.

5) Click on REGISTER APP and download google-service.json file.

6) click on FINISH.

Create Android Studio Project

1. create a new project in Android studio. File -> New Project use the same package name that you         have put in firebase app.
2. Copy the google-services.json file that you have download from firebase console  paste it in app           folder.
3. Open the build.gradle of project level and add the google dependency

build.gradle

dependencies {         classpath 'com.android.tools.build:gradle:2.2.0'         classpath 'com.google.gms:google-services:3.0.0'         // NOTE: Do not place your application dependencies here; they belong         // in the individual module build.gradle files     } 4. Open app->build.gradle and add firebase database dependency.At the very bottom of the file, apply plugin dependencies {     // Adding support library for this demo app     compile 'com.android.support:design:24.2.1'     compile 'com.google.firebase:firebase-core:9.6.1' } apply plugin: 'com.google.gms.google-services'

5. We need to add permission in menifest.xml file:

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WAKE_LOCK" />

6.  Model class use for log event

Product.java

package com.androidheight.firebaseanalytics;

public class Product {
    private int id;
    private String name;
    private String price;


    public int getId() {
        return id;
    }


    public void setId(int id) {
        this.id = id;
    }


    public String getName() {
        return name;
    }


    public void setName(String name) {
        this.name = name;
    }


    public String getPrice() {
        return price;
    }


    public void setPrice(String price) {
        this.price = price;
    }
}
