Create Script to Start a Player Session

In the Unity Editor, create a new C# script by going to:
Assets->Create->C# Script
Name the newly created script: UnityAnalyticsIntegration (naming must be exact for the script to work correctly)

Open Script and Copy Code

Double-click on the script to open your script in MonoDevelop. Completely replace the default generated code with the code below and click “Save” in MonoDevelop. The Unity Project ID that you see in the sample code below is unique to your game. It is used to link your Editor project to your Analytics dashboard.

Go to the Analytics Dashboard to get your unique, functional Project ID

using UnityEngine;
using System.Collections;
using UnityEngine.Cloud.Analytics;

public class UnityAnalyticsIntegration : MonoBehaviour {

    // Use this for initialization
    void Start () {

        const string projectId = "SAMPLE-UNITY-PROJECT-ID";
        UnityAnalytics.StartSDK (projectId);

    }

}
