Android AdMob Mediation Adapter

Android AdMob Mediation Adapter supports all our ad units including the unique Interscroller ad unit. 

AdMob/ display.io ad units mapping:

	display.io	AdMob
	Interscroller	Banner
	Headline Video	Banner
	Interstitial	Interstitial
	Infeed	Banner
	Medium Rectangle	Banner
	Banner	Banner

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:4.5.2.1’
implementation ‘com.brandio.ads:google-ads-adapter:4.5.2.2'

Follow guide to initialize DisplayIO SDK.

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.googleads.InterstitialAdapter for Interstitial ad unit or com.brandio.ads.adapters.googleads.InfeedAdapter for Infeed ad unit or com.brandio.ads.adapters.googleads.InterscrollerAdapter for Interscroller ad unit or com.brandio.ads.adapters.googleads.BannerAdapter for Banner ad unit or com.brandio.ads.adapters.googleads.MediumRectangleAdapter for Medium Rectangle ad unit or com.brandio.ads.adapters.googleads.OutStreamVideoAdapter for OutStreamVideo ad unit
and Parameter: <PLACEMENT_ID> where <PLACEMENT_ID> parameter taken from display.io apps page.

Note: Interscroller unit also requires position of ad in your RecyclerView custom event data:

6. Use Banner (Infeed) or Interstitial 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. Interscroller could be added in RecyclerView like Banner but it require additional step: Set up your placement with field to store reference to parent (RecyclerView object) Make sure you call it after DisplayIO SDK has beed initialized:

try {
    InterscrollerPlacement placement = (InterscrollerPlacement) Controller
                                       .getInstance().getPlacement(IS_PLACEMENT_ID);
    placement.setParentRecyclerView(recyclerView);
} catch (DioSdkException e) {
    e.printStackTrace();
}
