Global Settings

The MobileAds class provides global settings for Next Gen Mobile Ads SDK.

Video ad volume control

If your app has its own volume controls (such as custom music or sound effect volumes), disclosing app volume to Next Gen Mobile Ads SDK allows video ads to respect app volume settings. This ensures users receive video ads with the expected audio volume.

The device volume, controlled through volume buttons or OS-level volume slider, determines the volume for device audio output. However, apps can independently adjust volume levels relative to the device volume to tailor the audio experience. For app open, banner, interstitial, rewarded, and rewarded interstitial ad formats, you can report the relative app volume to the SDK through the static setUserControlledAppVolume() method. Valid ad volume values range from 0.0 (silent) to 1.0 (current device volume). Here's an example of how to report the relative app volume to the SDK:

Kotlin

override fun onCreate(savedInstanceState: Bundle?) {
  super.onCreate(savedInstanceState)

  val backgroundScope = CoroutineScope(Dispatchers.IO)
  backgroundScope.launch {
    // Initialize Next Gen Mobile Ads SDK on a background thread.
    MobileAds.initialize(
      this@MainActivity,
      // Sample AdMob app ID: ca-app-pub-3940256099942544~3347511713
      InitializationConfig.Builder("SAMPLE_APP_ID").build()
    ) {}
    
    // Set app volume to be half of current device volume.
    MobileAds.setUserControlledAppVolume(0.5f)
  }
}

Java

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);

  new Thread(
          () -> {
            // Initialize Next Gen Mobile Ads SDK on a background thread.
            MobileAds.initialize(
                this,
                // Sample AdMob app ID: ca-app-pub-3940256099942544~3347511713
                new InitializationConfig.Builder("SAMPLE_APP_ID")
                    .build(),
                initializationStatus -> {
                });
            
            // Set app volume to be half of current device volume.
            MobileAds.setUserControlledAppVolume(0.5f);
          })
      .start();
}

To inform the SDK that the app volume has muted, use the setUserMutedApp() method:

Kotlin

MobileAds.setUserMutedApp(true)

Java

MobileAds.setUserMutedApp(true);

By default, the app volume is set to 1 (the current device volume), and the app is not muted.

If your app has special requirements, you can set the optional SharedPreferences gad_has_consent_for_cookies. The SDK will enable limited ads (LTD) when the gad_has_consent_for_cookies preference is set to zero.

Kotlin

val sharedPrefs = PreferenceManager.getDefaultSharedPreferences(context)
// Set the value to 0 to enable limited ads.
sharedPrefs.edit().putInt("gad_has_consent_for_cookies", 0).apply()

Java

Context activity = getActivity();
SharedPreferences sharedPreferences =
  PreferenceManager.getDefaultSharedPreferences(activity);
// Set the value to 0 to enable limited ads.
sharedPreferences.edit().putInt("gad_has_consent_for_cookies", 0).apply();
