Global Settings

The MobileAds class provides global settings for the 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 the Google 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. You can report the relative app volume to the Mobile Ads SDK through the static setAppVolume() 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:

Java

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

    // Set app volume to be half of current device volume.
    MobileAds.setAppVolume(0.5f);
    ...
}

Kotlin

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

    // Set app volume to be half of current device volume.
    MobileAds.setAppVolume(0.5f)
    ...
}

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

Java

MobileAds.setAppMuted(true);

Kotlin

MobileAds.setAppMuted(true)

Unmuting the app volume reverts it to the previously set level. By default, the app volume for the Google Mobile Ads SDK is set to 1 (the current device volume).
