Unity Ads Monetization

Implement interstitial ads in Android

Implement interstitial ads in your Android app. Load ad content, display it through Java code, and use a listener to manage ad events.
Read time 1 minuteLast updated 17 days ago
To display a full-screen interstitial ad using the 
UnityAds
API:
  1. Initialize the SDK.
  2. Use the 
    load
     API to load an ad for the specified ad unit.
  3. After the ad loads, you can then display it using the 
    show
     API.

Interstitial ads example

In this example, you can invoke 
DisplayInterstitialAd
from anywhere in your game to show an interstitial ad as long as Unity Ads has successfully initialized. 
  import android.app.Activity;
import android.os.Bundle;
import android.util.Log;

import androidx.appcompat.app.AppCompatActivity;

import com.unity3d.ads.IUnityAdsLoadListener;
import com.unity3d.ads.IUnityAdsShowListener;

import com.unity3d.ads.IUnityAdsInitializationListener;
import com.unity3d.ads.UnityAds;

public class ShowInterstitialAd extends AppCompatActivity implements IUnityAdsInitializationListener  {

private String unityGameID = "1234567";
private Boolean testMode = true;
private String adUnitId = "video";

private IUnityAdsLoadListener loadListener = new IUnityAdsLoadListener() {
   @Override
   public void onUnityAdsAdLoaded(String placementId) {
      UnityAds.show((Activity)getApplicationContext(), adUnitId, new UnityAdsShowOptions(), showListener);
   }

   @Override
   public void onUnityAdsFailedToLoad(String placementId, UnityAds.UnityAdsLoadError error, String message) {
      Log.e("UnityAdsExample", "Unity Ads failed to load ad for " + placementId + " with error: [" + error + "] " + message);
   }
};

private IUnityAdsShowListener showListener = new IUnityAdsShowListener() {
   @Override
   public void onUnityAdsShowFailure(String placementId, UnityAds.UnityAdsShowError error, String message) {
      Log.e("UnityAdsExample", "Unity Ads failed to show ad for " + placementId + " with error: [" + error + "] " + message);
   }

   @Override
   public void onUnityAdsShowStart(String placementId) {
      Log.v("UnityAdsExample", "onUnityAdsShowStart: " + placementId);
   }

   @Override
   public void onUnityAdsShowClick(String placementId) {
      Log.v("UnityAdsExample", "onUnityAdsShowClick: " + placementId);
   }

   @Override
   public void onUnityAdsShowComplete(String placementId, UnityAds.UnityAdsShowCompletionState state) {
      Log.v("UnityAdsExample", "onUnityAdsShowComplete: " + placementId);
   }
};

@Override
protected void onCreate (Bundle savedInstanceState) {
   super.onCreate (savedInstanceState);
   setContentView (R.layout.activity_main);
   // Initialize the SDK:
   UnityAds.initialize(getApplicationContext(), unityGameID, testMode, this);
}

@Override
public void onInitializationComplete() {
   DisplayInterstitialAd();
}

@Override
public void onInitializationFailed(UnityAds.UnityAdsInitializationError error, String message) {
   Log.e("UnityAdsExample", "Unity Ads initialization failed with error: [" + error + "] " + message);
}

// Implement a function to load an interstitial ad. The ad will start to show after the ad has been loaded.
public void DisplayInterstitialAd () {
   UnityAds.load(adUnitId, loadListener);
}
}
