Google play: We found ad SDKs in your app

Question

I have this warning in the google play console, which tells me that I have ads in the app, but I did not use any ads in my app.

Ads Let us know whether your app contains ads. This includes ads delivered by third party ad networks. Make sure this information is accurate and is kept up to date. Learn more

We found ad SDKs in your app

This is Gradle dependencies, I did not know which library uses ads dependency, How I should know?

// Add the Firebase Crashlytics plugin.
apply plugin: 'com.google.firebase.crashlytics'

Answer 1

the ads dependencies come from firebase, exclude ads dependence from firebase

exclude group: 'com.google.android.gms', module : 'play-services-ads-identifier'

implementation ('com.google.firebase:firebase-core:18.0.3'){
        exclude group: 'com.google.android.gms', module : 'play-services-ads-identifier'
    }
    implementation ('com.google.firebase:firebase-invites:17.0.0'){
        exclude group: 'com.google.android.gms', module : 'play-services-ads-identifier'
    }
    implementation ('com.google.firebase:firebase-auth:20.0.3'){
        exclude group: 'com.google.android.gms', module : 'play-services-ads-identifier'
    }
    implementation ('com.google.firebase:firebase-messaging:21.1.0'){
        exclude group: 'com.google.android.gms', module : 'play-services-ads-identifier'
    }

implementation ('com.google.firebase:firebase-crashlytics:17.4.1'){
        exclude group: 'com.google.android.gms', module : 'play-services-ads-identifier'
    }
    implementation ('com.google.firebase:firebase-analytics:18.0.3'){
