Listener Usage

By implementing and providing ChartboostMediationFullscreenAdListener and ChartboostMediationBannerAdViewListener interfaces to the Chartboost Mediation objects, you can get notifications about the success, failure, and other lifecycle events of Mediation Ads.

ChartboostMediationFullscreenAdListener 🔗

You can implement the ChartboostMediationFullscreenAdListener interface to receive notifications about interstitial and rewarded ads loading, displaying, and closing.

• Kotlin
• Java

• val chartboostMediationFullscreenAdListener = object : ChartboostMediationFullscreenAdListener {
      override fun onAdCached(placementName: String, loadId: String, winningBidInfo: Map<String, String>, error: ChartboostMediationAdException?) {
          error?.let {
              Log.d(TAG, "Ad cache failed for placement: $placementName " + 
              "reason: ${it.message}")
          } ?: run {
              // Show the ad if it's ready
              Log.d(TAG, "Ad cached for placement: $placementName")
          }
      }
  
      override fun onAdShown(placementName: String, error: ChartboostMediationAdException?) {
          error?.let {
              Log.d(TAG, "Ad show failed for placement: $placementName " + 
              "reason: ${it.message}")
          } ?: run {
              Log.d(TAG, "Ad shown for placement: $placementName")
          }
      }
  
      override fun onAdClicked(placementName: String) {
          
          Log.d(TAG, "Ad clicked for placement: $placementName")
      }
  
      override fun onAdClosed(placementName: String, error: ChartboostMediationAdException?) {
          error?.let {
              Log.d(TAG, "Ad closed and there was an error for placement: $placementName " + 
              "reason: ${it.message}")
          } ?: run {
              Log.d(TAG, "Ad closed for placement: $placementName")
          }
      }
  
      override fun onAdImpressionRecorded(placementName: String) {
          Log.d(TAG, "Ad recorded impression for placement: $placementName")
      }
  
      override fun onAdRewarded(placementName: String) {
          Log.d(TAG, "Ad rewarded user for placement: $placementName")
      }
  }
  

• ChartboostMediationFullscreenAdListener chartboostMediationFullscreenAdListener = new ChartboostMediationFullscreenAdListener() {
      @Override
      public void onAdCached(@NonNull String placementName, @NonNull String loadId, @NonNull Map<String, String> winningBidInfo, @Nullable ChartboostMediationAdException error) {
          if (error != null) {
              Log.d(TAG, "Ad cache failed for placement: " + placementName + " reason: " + error.getMessage());
          } else {
              // Show the ad if it's ready
              Log.d(TAG, "Ad cached for placement: " + placementName);
          }
      }
   
      @Override
      public void onAdShown(@NonNull String placementName, @Nullable ChartboostMediationAdException error) {
          if (error != null) {
              Log.d(TAG, "Ad show failed for placement: " + placementName + " reason: " + error.getMessage());
          } else {
              Log.d(TAG, "Ad shown for placement: " + placementName);
          }
      }
   
      @Override
      public void onAdClicked(@NonNull String placementName) {
          Log.d(TAG, "Ad clicked for placement: " + placementName);
      }
   
      @Override
      public void onAdClosed(@NonNull String placementName, @Nullable ChartboostMediationAdException error) {
          if (error != null) {
              Log.d(TAG, "Ad closed with error for placement: " + placementName + " reason: " + error.getMessage());
          } else {
              Log.d(TAG, "Ad closed for placement: " + placementName);
          }
      }
  
      @Override
      public void onAdImpressionRecorded(@NonNull String placementName) {
          Log.d(TAG, "Ad recorded impression for placement: " + placementName);
      }
  
      @Override
      public void onAdRewarded(@NonNull String placementName) {
          Log.d(TAG, "Ad rewarded user for placement: " + placementName);
      }
  };
  

ChartboostMediationBannerAdViewListener 🔗

You can implement the ChartboostMediationBannerAdViewListener interface to receive notifications about banner ads loading, displaying, and closing.

Starting with version 3.0.0, the ChartboostMediationBannerAdViewListener no longer has the didShow and didClose callbacks. In addition, the didReceiveWinningBid callback is only called when the placement has auto-refresh disabled.

• Kotlin
• Java

• val chartboostMediationBannerAdViewListener = object : ChartboostMediationBannerAdViewListener {
      override fun onAdCached(
          placementName: String,
          loadId: String,
          winningBidInfo: HashMap<String, String>,
          error: ChartboostMediationAdException?
      ) {
          error?.let {
              Log.d(TAG, "Ad cache failed for placement: $placementName " + 
              "reason: ${it.message}" )
          } ?: run {
              // Show the ad if it's ready
              Log.d(TAG, "Ad cached for placement: $placementName with loadId $loadId and winningBidInfo $winningBidInfo")
          }
      }
  
      override fun onAdClicked(placementName: String) {
          Log.d(TAG, "Ad clicked for placement: $placementName")
      }
  
      override fun onAdImpressionRecorded(placementName: String) {
          Log.d(TAG, "Ad impression recorded for placement: $placementName")
      }
  }
  

• ChartboostMediationBannerAdViewListener chartboostMediationBannerAdViewListener = new ChartboostMediationBannerAdViewListener() {
  
      @Override
      public void onAdCached(@NonNull String placementName, @NonNull String loadId, @NonNull Map<String, String> winningBidInfo, @Nullable ChartboostMediationAdException error) {
          if (error != null) {
              Log.d(TAG, "Ad cache failed for placement: " + placementName + " reason: " + error.getMessage());
          } else {
              // Banners should automatically show if they are on screen
              Log.d(TAG, "Ad cached for placement: " + placementName + " with loadId " + loadId + " and winningBidInfo " + winningBidInfo);
          }
      }
  
      @Override
      public void onAdClicked(@NonNull String placementName) {
          Log.d(TAG, "Ad clicked for placement: " + placementName);
      }
  
      @Override
      public void onAdImpressionRecorded(@NonNull String placementName) {
          Log.d(TAG, "Ad impression recorded for placement: " + placementName);
      }
  };
  

Note Not all partner SDKs support the onAdClicked and onAdRewarded callbacks.
