# 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.

To display a full-screen interstitial ad using the `UnityAds` API:

1. [Initialize](/monetization/sdk-integration/android-sdk/initialize-sdk.md) the SDK.
2. Use the `load` API to load an ad for the specified placement.
3. After the ad loads, you can then display it using the `show` API.

## Interstitial ad 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.

> **Note:**
>
> Unity Ads requires access to the currently running Activity, so the following example uses `getApplicationContext()`.
> Because this might not be suitable for all implementations, some customization might be required (depending on the integration).

1. **Java**

   ```java
     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.UnityAdsShowOptions;
     import com.unity3d.ads.example.R;

     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);
     }
     }
   ```
