In AdMob projects ranging from 24.2.0 to 24.7.0, any version of Applovin will fail to request ads.

[张桓]

When I upgraded to AdMob 24.2.0 or later, all ad requests resulted in error code 3 or an internal error. After troubleshooting, I found that removing all Applovin configurations resolved the issue, and the ads were then requested and displayed correctly.

Here are my dependencies.

After removing `implementation 'com.google.android.gms:play-services-ads:24.7.0'` and `implementation 'com.google.ads.mediation:applovin:13.4.0.1'`, along with related Applovin configurations, it worked correctly.

implementation fileTree(dir: 'libs', includes: ['*.jar', '*.aar'])
implementation 'com.google.android.material:material:1.12.0'
implementation 'com.google.android.ump:user-messaging-platform:3.2.0'
implementation 'com.google.code.gson:gson:2.10.1'
implementation 'com.google.ads.mediation:applovin:13.4.0.1'
implementation 'com.android.volley:volley:1.2.1'
implementation 'com.google.android.gms:play-services-ads:24.7.0'
implementation 'com.applovin:applovin-sdk:13.4.0'
implementation("androidx.datastore:datastore-preferences-core:1.1.2")

Hi,

 

Thank you for getting back to us.

 

I have tested our sample project with the provided ad unit ID and dependencies, and the ads are loading successfully from AdMob.

 

Additionally, I have checked your AdMob account and found that mediation is not set up for the ad unit ID you provided. Please follow the steps to Integrate AppLovin with Mediation.

 

Please check the Guide to AdMob Mediation (bidding & waterfall) help center article for more information.

Thanks,
