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 enables 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 Google Mobile Ads SDK by calling the SetApplicationVolume() 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:

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

Warning: Lowering your app's audio volume reduces video ad eligibility and might reduce your app's ad revenue. You should only utilize this API if your app provides custom volume controls to the user, and the user's volume is properly reflected in the API.

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

    // Set app to be muted.
    MobileAds.SetApplicationMuted(true);

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

Warning: Muting your app reduces video ad eligibility and might reduce your app's ad revenue. You should only utilize this API if your app provides a custom mute control to the user, and the user's mute decision is properly reflected in the API.
