Android AdMob Mediation Adapter

Android AdMob Mediation Adapter supports all our ad units include unique Feed Interstitial ad unit. 

To set it up:

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:3.8.0’
implementation ‘com.brandio.ads:adapters-admob:3.8.0'

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.mopub.InterstitialAdapter for interstitial ad unit or com.brandio.ads.adapters.mopub.InfeedAdapter for infeed ad unit or com.brandio.ads.adapters.mopub.FeedInterstitialAdapter for feed interstitial ad unit or com.brandio.ads.adapters.mopub.BannerAdapter for banner ad unit or com.brandio.ads.adapters.mopub.MediumRectangleAdapter for medium rectangle ad unit or com.brandio.ads.adapters.mopub.RewardedVideoAdapter for rewarded video ad unit and Parameter: <PLACEMENT_ID> where <PLACEMENT_ID> parameter taken from display.io apps page.

Note: Feed Interstitial unit also require position of ad in your RecyclerView custom event data:

6. Use Banner (Infeed), Interstitial or Rewarded Video tutorials to get ads from AdMob.

7. Infeed could be added in RecyclerView by passing it as adapter’s constructor argument:

RecyclerViewAdapter( ... , @NonNull AdView adView) {

...

    this.adView = adView;

}

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

...

static class AdHolder extends RecyclerView.ViewHolder {
   AdHolder(View itemView) {
       super(itemView);
   }
}

...

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

...

   return new AdHolder(adView);
}

...

 9. Feed Interstitial could be added in RecyclerView with a few steps which require some modifications of RecyclerView adapter:

• First create nested static class for ad holder inside your adapter with field to store reference to parent (RecyclerView object):

static class AdHolder extends RecyclerView.ViewHolder {
    public ViewGroup parent;
    AdHolder(View itemView) {
        super(itemView);
    }
    public void setParent(ViewGroup parent) {
        this.parent = parent;
    }
}

• Second step is to create the holder for Ad at the proper position using AdHolder. Very important to set the parent for it as shown below:

public RecyclerView.ViewHolder onCreateViewHolder(@NonNull final ViewGroup parent, int viewType) {
    switch (viewType) {
        case AD_VIEW_TYPE:
            RelativeLayout rootAdLayout = FeedInterstitialContainer.getAdView(parent.getContext());
            AdHolder adHolder = new AdHolder(rootAdLayout);
            adHolder.setParent(parent);
            return adHolder;

        default:
            // your default list item
    }
}

•  Now the last step is to bind our ViewHolder with the ad

public void onBindViewHolder(@NonNull final RecyclerView.ViewHolder holder, final int position) {
    if (position == AD_POSITION) {
        try {
            FeedInterstitialContainer container = Controller.getInstance().getStoredContainer();
            if (container != null) {
                container.bindTo((ViewGroup)holder.itemView, ((AdHolder)holder).parent);
            } 
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
