Get Started with Google Analytics for Firebase for Unity

Google Analytics for Firebase collects usage and behavior data for your app. The SDK logs two primary types of information:

  • Events: What is happening in your app, such as user actions, system events, or errors.
  • User properties: Attributes you define to describe segments of your user base, such as language preference or geographic location.

Analytics automatically logs some events and user properties; you don't need to add any code to enable them. If your app needs to collect additional data, you can set up to 25 different Analytics user properties and log up to 500 different Analytics event types in your app. There is no limit on the total volume of events your app logs.

To access this data:

  1. In the Firebase console, open your project.
  2. Select Analytics from the menu to view the Analytics reporting dashboard.

The Events tab shows the event reports that are automatically created for each distinct type of Analytics event logged by your app. Read more about the Analytics reporting dashboard in the Firebase Help Center.

To help you get started, the Analytics SDK defines a number of suggested events that are common among different types of apps, including retail and ecommerce, travel, and gaming apps. To learn more about these events and when to use them, browse the Events and properties articles in the Firebase Help Center. To get the maximum detail in reports, log the suggested Analytics events that make sense for your app and their prescribed parameters. This also ensures that you benefit from the latest Google Analytics for Firebase features as they become available.

Before you begin

Before you can use the Google Analytics for Firebase, you will need to create a Firebase project, and add the Firebase Unity SDK packages to your Unity project.

Setup:

Prerequisites

Android

iOS

  • Unity 5.0 or later
  • Xcode 7.0 or later

If you don't have a Unity project already, you can download one of our quickstart samples and experiment with a specific Firebase feature. If you're using a quickstart, remember to get the bundle identifier from the project settings; you need it for the next step.

Set up your app in the Firebase console

To add Firebase to your app, you need a Firebase project and a Firebase configuration file for your app.

Create a Firebase project in the Firebase console if you don't already have one. If you already have an existing Google project associated with your mobile app, click Import Google Project. Otherwise, click Add project.

Android

  1. Click Add Firebase to your Android app and follow the setup steps. If you're importing an existing Google project, this may happen automatically and you can just download the config file.
  2. When prompted, enter your app's package name. It's important to enter the package name your app is using; this can only be set when you add an app to your Firebase project.
  3. Download a google-services.json file when instructed. You can redownload this file again at any time.
  4. Copy this file to anywhere inside your project's assets folder.

IOs

  1. Click Add Firebase to your iOS app and follow the setup steps. If you're importing an existing Google project, this may happen automatically and you can just download the config file.
  2. When prompted, enter your app's bundle ID. It's important to enter the bundle ID your app is using; this can only be set when you add an app to your Firebase project.
  3. Download a GoogleService-Info.plist file when instructed. You can redownload this file again at any time.
  4. Add the GoogleService-Info.plist file to the project.

  5. Drag the GoogleService-Info.plist downloaded from the Firebase console into any folder in the Unity project.

Add the Firebase Unity SDK to your app

  1. Download the Firebase Unity SDK.
  2. Select the Assets > Import Package > Custom Package menu item.
  3. Import the FirebaseAnalytics.unitypackage package from the Firebase Unity SDK, downloaded previously.
  4. When the Import Unity Package window appears, click the Import button.

Build your app

Android

  1. Select the File > Build Settings menu option.
  2. Select Android in the Platform list.
  3. Click Switch Platform to select Android as the target platform.
  4. Wait for the spinner (compiling) icon in the bottom right corner of the Unity status bar to stop.
  5. Click Build and Run.

iOS

  1. Select the File > Build Settings menu option.
  2. Select iOS in the Platform list.
  3. Click Switch Platform to select iOS as the target platform.
  4. Wait for the spinner (compiling) icon in the bottom right corner of the Unity status bar to stop.
  5. Click Build and Run.

Log events

You can immediately begin to log events with the LogEvent() method.

The following example logs events with various types of arguments:

// Log an event with no parameters.
Firebase.Analytics.FirebaseAnalytics
  .LogEvent(Firebase.Analytics.FirebaseAnalytics.EventLogin);

// Log an event with a float parameter
Firebase.Analytics.FirebaseAnalytics
  .LogEvent("progress", "percent", 0.4f);

// Log an event with an int parameter.
Firebase.Analytics.FirebaseAnalytics
  .LogEvent(
    Firebase.Analytics.FirebaseAnalytics.EventPostScore,
    Firebase.Analytics.FirebaseAnalytics.ParameterScore,
    42
  );

// Log an event with a string parameter.
Firebase.Analytics.FirebaseAnalytics
  .LogEvent(
    Firebase.Analytics.FirebaseAnalytics.EventJoinGroup,
    Firebase.Analytics.FirebaseAnalytics.ParameterGroupId,
    "spoon_welders"
  );

// Log an event with multiple parameters, passed as a struct:
Firebase.Analytics.Parameter[] LevelUpParameters = {
  new Firebase.Analytics.Parameter(
    Firebase.Analytics.FirebaseAnalytics.ParameterLevel, 5),
  new Firebase.Analytics.Parameter(
    Firebase.Analytics.FirebaseAnalytics.ParameterCharacter, "mrspoon"),
  new Firebase.Analytics.Parameter(
    "hit_accuracy", 3.14f)
};
Firebase.Analytics.FirebaseAnalytics.LogEvent(
  Firebase.Analytics.FirebaseAnalytics.EventLevelUp,
  LevelUpParameters);
