how can use GDPR consent in the advertising networks such as AdMob, Vungle, Ironsource, and Applovin?

to forward consent to the Google Mobile Ads SDK you can use this code

extras.putString("npa", "1");

AdRequest request = new AdRequest.Builder()
        .addNetworkExtrasBundle(AdMobAdapter.class, extras)
        .build();

in the IronSource If the user has opted out of “sale” of personal information

IronSource.setMetaData("do_not_sell","true");

If “sale” of personal information is permitted:

IronSource.setMetaData("do_not_sell","false");

in the Vungle, the following sample code sets the consent status to OPTED_IN Vungle.updateConsentStatus(Vungle.Consent.OPTED_IN, "1.0.0");

and this code sets the consent status to OPTED_OUT

Vungle.updateConsentStatus(Vungle.Consent.OPTED_OUT, "1.0.0");

AppLovin added the setHasUserContent and setIsAgeRestrictedUser methods. The following sample code shows how to pass consent information to the AppLovin SDK.

AppLovinPrivacySettings.setHasUserConsent(true, context);

if the user is known to be in an age-restricted category, you can also set the below flag to true.

AppLovinPrivacySettings.setIsAgeRestrictedUser(true, context);
