[Unity] 1. consentmanager SDK Integration

[Unity] 1. consentmanager SDK Integration

On this document, you'll find general information on how to integrate our SDK to your project. For further details, please refer to our API Reference documentation.

1. Installation

The consentmanager SDK for Android apps implements and provides functionality to inform the user about data protection and ask and collect consent from the user. It enables app-developers to easily integrate the consentmanager service into their app. As main features, we provide:

• Support both iOS and Android platforms.
• A bridge between Unity and native platform-specific CMP functionalities.
• An easy way to initialize, manage user consent, and handle privacy-related data.

In terms of compatibility, we have:

• Unity 20XX.X.X or later
• iOS (via DllImport)
• Android (via JNI)

Steps - High Level

Consent Manager Provider SDK Sequence Diagram

To illustrate the steps above, let's check in the diagram below three possible SDK sequence flows. 

1. When creating an instance using the Initialize() function, there are two possible outcomes. The first is when the consentmanger API informs the SDK that the CMP will not open, which triggers the OnCmpNotOpenedCallback. The second outcome is when the consent layer opens, allowing the user to interact with it, and this triggers the OnOpenCallback. Once the user gives consent and the consent is processed, the OnCmpCloseCallback is called.

Please note that the OnErrorCallback is represented by the red dashed arrow lines to provide examples of when errors may occur during the process.

2. Creating an instance and calling the OpenConsentLayerOnCheck functions will lead to a similar process. The difference is that by decoupling the creation of the instance and the check for the consentmanger API, you gain the ability to add business logic and interact with the libraries API.

3. Creating an instance and calling the OpenConsentLayer function will open the layer without checking the consentmanager, if it's necessary. If there is already given consent, the options and settings will be shown to the user. The process flow will look like this:

Importing the SDK package

In just two steps you can have all set up.

• • Download the latest release of the plugin.
  • Import the package into your Unity project using Assets > Import Package > Custom Package.

Config JSON

In the CmpSdkConfig.json you can set the native SDK Version for iOS and Android which will be used for the build process: 

Find the compatible native SDK Versions here: 

{
  "displayName": "Consentmanager SDK",
  "name": "CmpSdk",
  "androidBasePath": "net.consentmanager.sdk",
  "version": "1.0.0",
  "androidLibraryVersion": "x.xx.x",
  "iosLibraryVersion": "x.xx.x",
  "description": "Unity plugin helps you to use native Consentmanager functionality on Android and iOS."
}

Build Settings

To change the build settings go to Window -> CmpSdk 

iOS Build Settings

• Enable iOS Build Script: Toggle this to enable or disable the build script responsible for integrating the iOS SDK into the Unity project.
• xcFramework Path: Specify the path to the xcFramework directory. This path can be edited directly or browsed to using the accompanying button.
• Include Version Tag: When enabled, appends the iOS SDK version to the xcFramework path, allowing for version-specific configurations.
• Resulting Framework Path: Displays the fully resolved path to the xcFramework, including the SDK version if the version tag is included.
• Enable App Tracking Transparency: Toggle this to enable the App Tracking Transparency feature for iOS, which is necessary for user consent under iOS privacy guidelines.
• App Tracking Transparency Consent Message: A text field to input the custom message displayed to users when requesting consent for tracking. This message should be clear and concise, explaining why the consent is needed.

Android Build Settings

• Enable Android Build Script: Toggle to enable or disable the build script for integrating the Android SDK into the Unity project. 
• Integrate Custom Layout: When enabled, this allows the use of a custom layout for the consent layer for the fragment UIView.
  

  If you are willing to use a custom layout with fragments, make sure that your Unity Project adds the appcompat dependency. Add a custom main Template: 
  Assets/Plugins/Android/mainTemplate.gradle
  and add the dependency:
  implementation 'androidx.appcompat:appcompat:1.x.x'

2. Initializing the SDK

Follow these steps to start using the plugin.

Initializing the ConsentTool - Automatically

Within the app-start (usually the regular override onCreate() function) , you must create an instance of class CMPConsentTool.  The initialize() function will automatically fetch the necessary data from our server and determine if the consent screen needs to be shown or not. If so, the SDK will automatically show the consent screen at this point, collect the data and provide the data to the app. The instance can then be used in order to get consent details from the SDK in order to use it in the app.

Example of initialization, using the automatic behaviour of the Initialize() method.  

public string codeId = "<YOUR-CONSENTMANAGER-APP-ID>", // example: b238acdf1a
public string domain = "<YOUR-CONSENTMANAGER-APP-DOMAIN>", // example: delivery.consentmanager.net
public string appName = "<YOUR-CONSENTMANAGER-APP-NAME>", // example: testApp
public string language = "<YOUR-CONSENTMANAGER-APP-LANGUAGE>" // example: DE

CmpManager.Instance.Initialize(domain, codeId, appName, language);                

For domain use the Server-Domain found in your consentmanager account under Menu > CMPs > Get Codes for Apps. For codeID use the Code-ID found on the same page in your consentmanger account. The appName can be used in order to distinguish different apps in the consentmanager reporting. For the language, you can either use an empty string ("") for auto-detection or a 2-letter language code ("EN", "DE", "FR" and so on).

Initializing the ConsentTool - Manually

The SDK offers, for the sake of flexibility, a way to manually display the consent layer, as demonstrated below: 

bool isConsentRequired = await _cmpManager.CheckConsentIsRequired();
if (isConsentRequired)
{
	_cmpManager.OpenConsentLayer();
}

3. Using the SDK

Checking for consent

Check Consent: Check if the user has given consent:

bool hasConsent = CmpManager.Instance.HasConsent();

Callbacks: Set callback listeners for various events:

CmpManager.Instance.AddEventListeners(OnOpen, OnClose, OnNotOpened, OnCmpButtonClicked, OnError);

Purpose and Vendor Checks: Check for consent related to specific purposes and vendors:

bool hasPurpose = CmpManager.Instance.HasPurpose(id);
bool hasVendor = CmpManager.Instance.HasVendor(id);

Export Data: Export CMP data:

string cmpString = CmpManager.Instance.ExportCmpString();

Event Listener

Custom Layout

Unity supports different custom layouts: 

        public enum ScreenConfig
        {
            FullScreen,
            HalfScreenBottom,
            HalfScreenTop,
            CenterScreen,
            SmallCenterScreen,
            LargeTopScreen,
            LargeBottomScreen,
        }

Example usage: 

            _cmpConfig = new CmpConfig(CodeId, Domain, AppName, Language)
            {
                Debug = true,
                Timeout = 8000
            };

                _cmpConfig.UIConfig.screenConfig = (CmpUIConfig.ScreenConfig) Enum.Parse(typeof(CmpUIConfig.ScreenConfig), s);  
                _cmpManager.SetUIConfig(_cmpConfig.UIConfig); 

Google Consent Mode

Reference documentation : Get started with Google Firebase for Unity

Integration : Unity Setup

To use the google consent mode the CMP Unity SDK supports an interface to set the google consent status: 

// public class CmpSampleScript : MonoBehaviour, IOnCmpGoogleConsentUpdatedCallback { ... 
// Make sure to implement the Interface IOnCmpGoogleConsentUpdatedCallback
public void OnGoogleConsentUpdated(CmpGoogleConsentModeStatus status)
{
// Convert CmpGoogleConsentModeStatus to Firebase compatible dictionary
var firebaseConsentDict = new Dictionary<ConsentType, ConsentStatus>();

foreach (var consent in status.ConsentDictionary)
{
// Convert GoogleConsentType to Firebase ConsentType
var firebaseConsentType = ConvertToFirebaseConsentType(consent.Key);

// Convert GoogleConsentStatus to Firebase ConsentStatus
var firebaseConsentStatus = ConvertToFirebaseConsentStatus(consent.Value);

firebaseConsentDict[firebaseConsentType] = firebaseConsentStatus;
}

// Apply the consent settings to Firebase Analytics
FirebaseAnalytics.SetConsent(firebaseConsentDict);
AppendLog($"Google Consent Mode: {firebaseConsentDict}");
}

private static ConsentType ConvertToFirebaseConsentType(GoogleConsentType googleConsentType)
{
return googleConsentType switch
{
GoogleConsentType.AnalyticsStorage => ConsentType.AnalyticsStorage,
GoogleConsentType.AdStorage => ConsentType.AdStorage,
GoogleConsentType.AdUserData => ConsentType.AdUserData,
GoogleConsentType.AdPersonalization => ConsentType.AdPersonalization,
_ => throw new InvalidEnumArgumentException($"Unknown GoogleConsentType: {googleConsentType}")
};
}

private static ConsentStatus ConvertToFirebaseConsentStatus(GoogleConsentStatus googleConsentStatus)
{
return googleConsentStatus switch
{
GoogleConsentStatus.Granted => ConsentStatus.Granted,
GoogleConsentStatus.Denied => ConsentStatus.Denied,
_ => throw new InvalidEnumArgumentException($"Unknown GoogleConsentStatus: {googleConsentStatus}")
};
}

in this example the OnGoogleConsentUpdate callback is called when the user gives a consent. 

FirebaseAnalytics.SetConsent(firebaseConsentDict);

In this line the Consent Status is set to Firebase Analytics. The other two functions are mapping the CMP Consent Status to the Google Consent Types and Status.
