Android AdMob Mediation Adapter

1. Add the adapter to your project

Edit your project's build.gradle file in order to declare our maven repository:

 repositories {
    google()
    jcenter()
    maven { url "http://maven.display.io/" }
 }

Add the following dependencies to your app-module's build.gradle file:

implementation ‘com.brandio.ads:sdk:3.4.2’
implementation ‘com.brandio.ads:adapters-admob:3.4.2'

2. Create a Google AdMob account and register an app.

3. Use Quick start from Google to setup AdMob SDK.

4. Create a mediation group.

5. In Ad sources section switch off AdMob Network and add a custom event for each ad unit using Class Name com.brandio.ads.adapters.admob.InterstitialAdapter for interstitial ad unit or com.brandio.ads.adapters.admob.BannerAdapter for banner ad unit or com.brandio.ads.adapters.admob.RewardedVideoAdapter for rewarded video ad unit and Parameter: <PLACEMENT_ID> where <PLACEMENT_ID> parameter taken from display.io apps page.

...

    this.adView = adView;

}

and be shown in particular position with help of RecyclerView.ViewHolder subclass in RecyclerView.Adapter.onCreateViewHolder method:

public RecyclerView.ViewHolder onCreateViewHolder(@NonNull final
ViewGroup parent, int viewType) {

...

   return new AdHolder(adView);
}
