Set User Properties

User properties are attributes you define to describe segments of your user base, such as language preference or geographic location.

Analytics automatically logs some 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 in your app.

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 8.0 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.

To create a Firebase project:

  1. Create a Firebase project in the Firebase console, if you don't already have one. Click Add project. If you already have an existing Google project associated with your mobile app, select it from the Project name drop down menu. Otherwise, enter a project name to create a new project.
  2. Optional: Edit your Project ID. Your project is given a unique ID automatically, and it's used in publicly visible Firebase features such as database URLs and your Firebase Hosting subdomain. You can change it now if you want to use a specific subdomain.
  3. Follow the remaining setup steps and click Create project (or Add Firebase if you're using an existing project) to begin provisioning resources for your project. This typically takes a few minutes. When the process completes, you'll be taken to the project overview.

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. During the process, you'll download a google-services.json file. You can download this file again at any time.
  4. After you add the initialization code, run your app to send verification to the Firebase console that you've successfully installed Firebase.

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. During the process, you'll download a GoogleService-Info.plist file. You can download this file again at any time.
  4. After you add the initialization code, run your app to send verification to the Firebase console that you've successfully installed Firebase.
  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.

Initialize the SDK

The Firebase Unity SDK on Android requires Google Play services, which must be up-to-date before the SDK can be used. The following code should be added at the start of your application to check for and optionally update Google Play services to the version required by the Firebase Unity SDK before calling any other methods in the SDK.

Firebase.FirebaseApp.CheckAndFixDependenciesAsync().ContinueWith(task => {
  var dependencyStatus = task.Result;
  if (dependencyStatus == Firebase.DependencyStatus.Available) {
    // Set a flag here indiciating that Firebase is ready to use by your
    // application.
  } else {
    UnityEngine.Debug.LogError(System.String.Format(
      "Could not resolve all Firebase dependencies: {0}", dependencyStatus));
    // Firebase Unity SDK is not safe to use here.
  }
});

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.

Set user properties

You can set Analytics user properties to describe the users of your app. You can analyze behaviors of various user segments by applying these properties as filters to your reports.

Set a user property as follows:

  1. Register the property in the Analytics tab of the Firebase console.

  2. Add code to set an Analytics user property with the SetUserProperty() method. You can use the name and value of your choosing for each property.

The following example shows adding a hypothetical favorite food property, which assigns the value in the string mFavoriteFood to the active user:

Firebase.Analytics.FirebaseAnalytics.SetUserProperty("favorite_food", "ice cream");

You can access this data as follows:

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

The User Properties tab shows a list of user properties that you have defined for your app. You can use these properties as a filter on many of the reports available in Google Analytics for Firebase. Read more about the Analytics reporting dashboard in the [Firebase Help Center.][helpcenter]
