Get started

The Google User Messaging Platform (UMP) SDK is a privacy and messaging tool to help you manage privacy choices. For more information, see About Privacy & messaging.

Prerequisites

Android API level 21 or higher

Create a message type

Create user messages with one of the Available user message types under the Privacy & messaging tab of your Ad Manager account. The UMP SDK attempts to display a privacy message created from the Ad Manager Application ID set in your project.

For more details, see About privacy and messaging.

Install with Gradle

Add the dependency for the Google User Messaging Platform SDK to your module's app-level Gradle file, normally app/build.gradle:

dependencies {
  implementation("com.google.android.ump:user-messaging-platform:3.0.0")
}

After making the changes to your app's build.gradle, be sure to sync your project with Gradle files.

Add the application ID

You can find your application ID in the Ad Manager UI. Add the ID to your AndroidManifest.xml with the following code snippet:

<manifest>
  <application>
    <meta-data
        android:name="com.google.android.gms.ads.APPLICATION_ID"
        android:value="ca-app-pub-xxxxxxxxxxxxxxxx~yyyyyyyyyy"/>
  </application>
</manifest>

Gather consent

To gather consent, complete the following steps:

Request for the most recent user consent information.
Load and present a consent form, if required.

You should request an update of the user's consent information at every app launch, using requestConsentInfoUpdate(). This request checks the following:

Whether consent is required. For example, consent is required for the first time, or the previous consent decision expired.
Whether a privacy options entry point is required. Some privacy messages require apps to allow users to modify their privacy options at any time.

Load and present a privacy message form if required

After you have received the most up-to-date consent status, call loadAndShowConsentFormIfRequired() to load any forms required to collect user consent. After loading, the forms present immediately.

The following code demonstrates how to request the user's latest consent information. If required, the code loads and presents a privacy message form:

Java


// Requesting an update to consent information should be called on every app launch.
consentInformation.requestConsentInfoUpdate(
    activity,
    params,
    () ->
        UserMessagingPlatform.loadAndShowConsentFormIfRequired(
            activity,
            formError -> {
              // Consent has been gathered.
              onConsentGatheringCompleteListener.consentGatheringComplete(formError);
            }),
    requestConsentError ->
        onConsentGatheringCompleteListener.consentGatheringComplete(requestConsentError));GoogleMobileAdsConsentManager.java

Kotlin


// Requesting an update to consent information should be called on every app launch.
consentInformation.requestConsentInfoUpdate(
  activity,
  params,
  {
    UserMessagingPlatform.loadAndShowConsentFormIfRequired(activity) { formError ->
      // Consent has been gathered.
      onConsentGatheringCompleteListener.consentGatheringComplete(formError)
    }
  },
  { requestConsentError ->
    onConsentGatheringCompleteListener.consentGatheringComplete(requestConsentError)
  },
)GoogleMobileAdsConsentManager.kt

Privacy options

Some privacy message forms are presented from a publisher-rendered privacy options entry point, letting users manage their privacy options at any time. To learn more about which message your users see at the privacy options entry point, see Available user message types.

Check if a privacy options entry point is required

After you have called requestConsentInfoUpdate(), check ConsentInformation.PivacyOptionsRequirementStatus to determine if a privacy options entry point is required for your app:

Java


/** Helper variable to determine if the privacy options form is required. */
public boolean isPrivacyOptionsRequired() {
  return consentInformation.getPrivacyOptionsRequirementStatus()
      == PrivacyOptionsRequirementStatus.REQUIRED;
}
GoogleMobileAdsConsentManager.java

Kotlin


/** Helper variable to determine if the privacy options form is required. */
val isPrivacyOptionsRequired: Boolean
  get() =
    consentInformation.privacyOptionsRequirementStatus ==
      ConsentInformation.PrivacyOptionsRequirementStatus.REQUIRED
GoogleMobileAdsConsentManager.kt

Add a visible element to your app

If a privacy entry point is required, add a visible and interactable UI element to your app that presents the privacy options form. If a privacy entry point is not required, configure your UI element to be not visible and interactable.

Java


if (googleMobileAdsConsentManager.isPrivacyOptionsRequired()) {
  // Regenerate the options menu to include a privacy setting.
  invalidateOptionsMenu();
}MyActivity.java

Kotlin


if (googleMobileAdsConsentManager.isPrivacyOptionsRequired) {
  // Regenerate the options menu to include a privacy setting.
  invalidateOptionsMenu()
}MainActivity.kt

Present the privacy options form

When the user interacts with your element, present the privacy options form:

Java


UserMessagingPlatform.showPrivacyOptionsForm(activity, onConsentFormDismissedListener);GoogleMobileAdsConsentManager.java

Kotlin


UserMessagingPlatform.showPrivacyOptionsForm(activity, onConsentFormDismissedListener)GoogleMobileAdsConsentManager.kt

Request ads

Before requesting ads in your app, check if you have obtained consent from the user using canRequestAds(). There are two places to check while gathering consent:

After consent has been gathered in the current session.
Immediately after you have called requestConsentInfoUpdate(). It is possible consent has been obtained in the previous session. As a latency best practice, we recommend not waiting for the callback to complete so you can start loading ads as soon as possible after your app launches.

If an error occurs during the consent gathering process, you should still check if you can request ads. The UMP SDK uses the consent status from the previous session.

The following code checks if you can request ads during the consent gathering process:

Java


googleMobileAdsConsentManager.gatherConsent(
    this,
    consentError -> {
      if (consentError != null) {
        // Consent not obtained in current session.
        Log.w(
            TAG,
            String.format("%s: %s", consentError.getErrorCode(), consentError.getMessage()));
      }

      if (googleMobileAdsConsentManager.canRequestAds()) {
        initializeMobileAdsSdk();
      }
      // ...
    });

// This sample attempts to load ads using consent obtained in the previous session.
if (googleMobileAdsConsentManager.canRequestAds()) {
  initializeMobileAdsSdk();
}

Kotlin


googleMobileAdsConsentManager.gatherConsent(this) { error ->
  if (error != null) {
    // Consent not obtained in current session.
    Log.d(TAG, "${error.errorCode}: ${error.message}")
  }

  if (googleMobileAdsConsentManager.canRequestAds) {
    initializeMobileAdsSdk()
  }
  // ...
}

// This sample attempts to load ads using consent obtained in the previous session.
if (googleMobileAdsConsentManager.canRequestAds) {
  initializeMobileAdsSdk()
}

The following code sets up the Google Mobile Ads SDK after the user's consent is gathered:

Java


private void initializeMobileAdsSdk() {
  if (isMobileAdsInitializeCalled.getAndSet(true)) {
    return;
  }
  new Thread(
          () -> {
            // Initialize the Google Mobile Ads SDK on a background thread.
            MobileAds.initialize(this, initializationStatus -> {});

            // Load an ad on the main thread.
            runOnUiThread(this::loadBanner);
          })
      .start();
}
MyActivity.java

Kotlin


private fun initializeMobileAdsSdk() {
  if (isMobileAdsInitializeCalled.getAndSet(true)) {
    return
  }
  CoroutineScope(Dispatchers.IO).launch {
    // Initialize the Google Mobile Ads SDK on a background thread.
    MobileAds.initialize(this@MainActivity) {}

    runOnUiThread {
      // Load an ad on the main thread.
      loadBanner()
    }
  }
}
MainActivity.kt

Testing

If you want to test the integration in your app as you're developing, follow these steps to programmatically register your test device. Be sure to remove the code that sets these test device IDs before you release your app.

Call requestConsentInfoUpdate().
Check the log output for a message similar to the following example, which shows your device ID and how to add it as a test device:
```
Use new ConsentDebugSettings.Builder().addTestDeviceHashedId("33BE2250B43518CCDA7DE426D04EE231") to set this as a debug device.
```
Copy your test device ID to your clipboard.

Modify your code to call ConsentDebugSettings.Builder().TestDeviceHashedIds and pass in a list of your test device IDs.

Java

ConsentDebugSettings debugSettings = new ConsentDebugSettings.Builder(this)
    .addTestDeviceHashedId("TEST-DEVICE-HASHED-ID")
    .build();

ConsentRequestParameters params = new ConsentRequestParameters
    .Builder()
    .setConsentDebugSettings(debugSettings)
    .build();

consentInformation = UserMessagingPlatform.getConsentInformation(this);
// Include the ConsentRequestParameters in your consent request.
consentInformation.requestConsentInfoUpdate(
    this,
    params,
    // ...
);

Kotlin

val debugSettings = ConsentDebugSettings.Builder(this)
    .addTestDeviceHashedId("TEST-DEVICE-HASHED-ID")
    .build()

val params = ConsentRequestParameters
    .Builder()
    .setConsentDebugSettings(debugSettings)
    .build()

consentInformation = UserMessagingPlatform.getConsentInformation(this)
// Include the ConsentRequestParameters in your consent request.
consentInformation.requestConsentInfoUpdate(
    this,
    params,
    // ...
)

Force a geography

The UMP SDK provides a way to test your app's behavior as though the device was located in the EEA or UK using DebugGeography. Note that debug settings only work on test devices.

Java

ConsentDebugSettings debugSettings = new ConsentDebugSettings.Builder(this)
    .setDebugGeography(ConsentDebugSettings.DebugGeography.DEBUG_GEOGRAPHY_EEA)
    .addTestDeviceHashedId("TEST-DEVICE-HASHED-ID")
    .build();

ConsentRequestParameters params = new ConsentRequestParameters
    .Builder()
    .setConsentDebugSettings(debugSettings)
    .build();

consentInformation = UserMessagingPlatform.getConsentInformation(this);
// Include the ConsentRequestParameters in your consent request.
consentInformation.requestConsentInfoUpdate(
    this,
    params,
    ...
);

Kotlin

val debugSettings = ConsentDebugSettings.Builder(this)
    .setDebugGeography(ConsentDebugSettings.DebugGeography.DEBUG_GEOGRAPHY_EEA)
    .addTestDeviceHashedId("TEST-DEVICE-HASHED-ID")
    .build()

val params = ConsentRequestParameters
    .Builder()
    .setConsentDebugSettings(debugSettings)
    .build()

consentInformation = UserMessagingPlatform.getConsentInformation(this)
// Include the ConsentRequestParameters in your consent request.
consentInformation.requestConsentInfoUpdate(
    this,
    params,
    ...
)

Reset consent state

When testing your app with the UMP SDK, you might find it helpful to reset the state of the SDK so that you can simulate a user's first install experience. The SDK provides the reset() method to do this.

Java

consentInformation.reset();

Kotlin

consentInformation.reset()
