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 AdMob account. The UMP SDK attempts to display a privacy message created from the AdMob 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 AdMob 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>

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.

Here is an example of how to check the status from the MainActivity in the onCreate() method.

Java

package com.example.myapplication;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;

import com.google.android.ump.ConsentInformation;
import com.google.android.ump.ConsentRequestParameters;
import com.google.android.ump.FormError;
import com.google.android.ump.UserMessagingPlatform;

public class MainActivity extends AppCompatActivity {
  private ConsentInformation consentInformation;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // Create a ConsentRequestParameters object.
    ConsentRequestParameters params = new ConsentRequestParameters
        .Builder()
        .build();

    consentInformation = UserMessagingPlatform.getConsentInformation(this);
    consentInformation.requestConsentInfoUpdate(
        this,
        params,
        (OnConsentInfoUpdateSuccessListener) () -> {
          // TODO: Load and show the privacy message form.
        },
        (OnConsentInfoUpdateFailureListener) requestConsentError -> {
          // Consent gathering failed.
          Log.w(TAG, String.format("%s: %s",
              requestConsentError.getErrorCode(),
              requestConsentError.getMessage()));
        });
  }
}

Kotlin

package com.example.myapplication

import com.google.android.ump.ConsentInformation
import com.google.android.ump.ConsentInformation.OnConsentInfoUpdateFailureListener
import com.google.android.ump.ConsentInformation.OnConsentInfoUpdateSuccessListener
import com.google.android.ump.ConsentRequestParameters
import com.google.android.ump.UserMessagingPlatform

class MainActivity : AppCompatActivity() {
  private lateinit var consentInformation: ConsentInformation

  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    // Create a ConsentRequestParameters object.
    val params = ConsentRequestParameters
        .Builder()
        .build()

    consentInformation = UserMessagingPlatform.getConsentInformation(this)
    consentInformation.requestConsentInfoUpdate(
        this,
        params,
        ConsentInformation.OnConsentInfoUpdateSuccessListener {
          // TODO: Load and show the privacy message form.
        },
        ConsentInformation.OnConsentInfoUpdateFailureListener {
          requestConsentError ->
          // Consent gathering failed.
          Log.w(TAG, "${requestConsentError.errorCode}: ${requestConsentError.message}")
        })
  }
}

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.

Java

public class MainActivity extends AppCompatActivity {
  private ConsentInformation consentInformation;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // Create a ConsentRequestParameters object.
    ConsentRequestParameters params = new ConsentRequestParameters
        .Builder()
        .build();

    consentInformation = UserMessagingPlatform.getConsentInformation(this);
    consentInformation.requestConsentInfoUpdate(
        this,
        params,
        (OnConsentInfoUpdateSuccessListener) () -> {
          UserMessagingPlatform.loadAndShowConsentFormIfRequired(
            this,
            (OnConsentFormDismissedListener) loadAndShowError -> {
              if (loadAndShowError != null) {
                // Consent gathering failed.
                Log.w(TAG, String.format("%s: %s",
                    loadAndShowError.getErrorCode(),
                    loadAndShowError.getMessage()));
              }

              // Consent has been gathered.
            }
          );
        },
        (OnConsentInfoUpdateFailureListener) requestConsentError -> {
          // Consent gathering failed.
          Log.w(TAG, String.format("%s: %s",
              requestConsentError.getErrorCode(),
              requestConsentError.getMessage()));
        });
  }
}

Kotlin

class MainActivity : AppCompatActivity() {
  private lateinit var consentInformation: ConsentInformation

  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    // Create a ConsentRequestParameters object.
    val params = ConsentRequestParameters
        .Builder()
        .build()

    consentInformation = UserMessagingPlatform.getConsentInformation(this)
    consentInformation.requestConsentInfoUpdate(
        this,
        params,
        ConsentInformation.OnConsentInfoUpdateSuccessListener {
          UserMessagingPlatform.loadAndShowConsentFormIfRequired(
            this@MainActivity,
            ConsentForm.OnConsentFormDismissedListener {
              loadAndShowError ->
              if (loadAndShowError != null) {
                // Consent gathering failed.
                Log.w(TAG, "${loadAndShowError.errorCode}: ${loadAndShowError.message}")
              }

              // Consent has been gathered.
            }
          )
        },
        ConsentInformation.OnConsentInfoUpdateFailureListener {
          requestConsentError ->
          // Consent gathering failed.
          Log.w(TAG, "${requestConsentError.errorCode}: ${requestConsentError.message}")
        })
  }
}

If you need to perform any actions after the user has made a choice or dismissed the form, place that logic in the callback for your form.

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.

To implement a privacy options entry point, complete the following steps:

  1. Check ConsentInformation.PrivacyOptionsRequirementStatus.
  2. If a privacy options entry point is required, add a visible and interactable UI element to your app.
  3. Trigger the privacy options form using showPrivacyOptionsForm().

The following code example demonstrates these steps:

Java

private final ConsentInformation consentInformation;

// Show a privacy options button if required.
public boolean isPrivacyOptionsRequired() {
  return consentInformation.getPrivacyOptionsRequirementStatus()
      == PrivacyOptionsRequirementStatus.REQUIRED;
}

@Override
protected void onCreate(Bundle savedInstanceState) {
  // ...

  consentInformation = UserMessagingPlatform.getConsentInformation(this);
  consentInformation.requestConsentInfoUpdate(
      this,
      params,
      (OnConsentInfoUpdateSuccessListener) () -> {
        UserMessagingPlatform.loadAndShowConsentFormIfRequired(
          this,
          (OnConsentFormDismissedListener) loadAndShowError -> {
            // ...

            // Consent has been gathered.

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

@Override
public boolean onCreateOptionsMenu(Menu menu) {
  getMenuInflater().inflate(R.menu.action_menu, menu);
  MenuItem moreMenu = menu.findItem(R.id.action_more);
  moreMenu.setVisible(isPrivacyOptionsRequired());
  return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
  // ...

  popup.setOnMenuItemClickListener(
      popupMenuItem -> {
        if (popupMenuItem.getItemId() == R.id.privacy_settings) {
          // Present the privacy options form when a user interacts with
          // the privacy settings button.
          UserMessagingPlatform.showPrivacyOptionsForm(
              this,
              formError -> {
                if (formError != null) {
                  // Handle the error.
                }
              }
          );
          return true;
        }
        return false;
      });
  return super.onOptionsItemSelected(item);
}

Kotlin

private val consentInformation: ConsentInformation =
  UserMessagingPlatform.getConsentInformation(context)

// Show a privacy options button if required.
val isPrivacyOptionsRequired: Boolean
  get() =
    consentInformation.privacyOptionsRequirementStatus ==
      ConsentInformation.PrivacyOptionsRequirementStatus.REQUIRED

override fun onCreate(savedInstanceState: Bundle?) {
  // ...
  consentInformation = UserMessagingPlatform.getConsentInformation(this)
  consentInformation.requestConsentInfoUpdate(
      this,
      params,
      ConsentInformation.OnConsentInfoUpdateSuccessListener {
        UserMessagingPlatform.loadAndShowConsentFormIfRequired(
          this@MainActivity,
          ConsentForm.OnConsentFormDismissedListener {
            // ...

            // Consent has been gathered.

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

override fun onCreateOptionsMenu(menu: Menu?): Boolean {
  menuInflater.inflate(R.menu.action_menu, menu)
  menu?.findItem(R.id.action_more)?.apply {
    isVisible = isPrivacyOptionsRequired
  }
  return super.onCreateOptionsMenu(menu)
}

override fun onOptionsItemSelected(item: MenuItem): Boolean {
  // ...

  popup.setOnMenuItemClickListener { popupMenuItem ->
    when (popupMenuItem.itemId) {
      R.id.privacy_settings -> {
        // Present the privacy options form when a user interacts with
        // the privacy settings button.
        UserMessagingPlatform.showPrivacyOptionsForm(this) { formError ->
          formError?.let {
            // Handle the error.
          }
        }
        true
      }
      else -> false
    }
  }
  return super.onOptionsItemSelected(item)
}

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 attempt to request ads. The UMP SDK uses the consent status from the previous session.

Java

public class MainActivity extends AppCompatActivity {
  private ConsentInformation consentInformation;
  // Use an atomic boolean to initialize the Google Mobile Ads SDK and load ads once.
  private final AtomicBoolean isMobileAdsInitializeCalled = new AtomicBoolean(false);
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // Create a ConsentRequestParameters object.
    ConsentRequestParameters params = new ConsentRequestParameters
        .Builder()
        .build();

    consentInformation = UserMessagingPlatform.getConsentInformation(this);
    consentInformation.requestConsentInfoUpdate(
        this,
        params,
        (OnConsentInfoUpdateSuccessListener) () -> {
          UserMessagingPlatform.loadAndShowConsentFormIfRequired(
            this,
            (OnConsentFormDismissedListener) loadAndShowError -> {
              if (loadAndShowError != null) {
                // Consent gathering failed.
                Log.w(TAG, String.format("%s: %s",
                    loadAndShowError.getErrorCode(),
                    loadAndShowError.getMessage()));
              }

              // Consent has been gathered.
              if (consentInformation.canRequestAds()) {
                initializeMobileAdsSdk();
              }
            }
          );
        },
        (OnConsentInfoUpdateFailureListener) requestConsentError -> {
          // Consent gathering failed.
          Log.w(TAG, String.format("%s: %s",
              requestConsentError.getErrorCode(),
              requestConsentError.getMessage()));
        });
    
    // Check if you can initialize the Google Mobile Ads SDK in parallel
    // while checking for new consent information. Consent obtained in
    // the previous session can be used to request ads.
    if (consentInformation.canRequestAds()) {
      initializeMobileAdsSdk();
    }
  }
  
  private void initializeMobileAdsSdk() {
    if (isMobileAdsInitializeCalled.getAndSet(true)) {
      return;
    }

    new Thread(
            () -> {
              // Initialize the Google Mobile Ads SDK on a background thread.
              
              MobileAds.initialize(this, initializationStatus -> {});
              runOnUiThread(
                  () -> {
                    // TODO: Request an ad.
                    // loadInterstitialAd();
                  });
              
            })
        .start();
  }

    setContentView(R.layout.activity_main)

    // Create a ConsentRequestParameters object.
    val params = ConsentRequestParameters
        .Builder()
        .build()

    consentInformation = UserMessagingPlatform.getConsentInformation(this)
    consentInformation.requestConsentInfoUpdate(
        this,
        params,
        ConsentInformation.OnConsentInfoUpdateSuccessListener {
          UserMessagingPlatform.loadAndShowConsentFormIfRequired(

    // while checking for new consent information. Consent obtained in
    // the previous session can be used to request ads.
    if (consentInformation.canRequestAds()) {
      initializeMobileAdsSdk()

  private fun initializeMobileAdsSdk() {

    val backgroundScope = CoroutineScope(Dispatchers.IO)
    backgroundScope.launch {
      
      MobileAds.initialize(this@MainActivity) {}
      runOnUiThread {
        // TODO: Request an ad.
        // loadInterstitialAd()
      }
      
    }
  }

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.

  1. Call requestConsentInfoUpdate().
  2. 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.
    
  3. Copy your test device ID to your clipboard.

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

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 setDebugGeography(). 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,
    ...
)

In 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()
