獎勵廣告自訂事件

必要條件

完成自訂事件設定。

請求獎勵廣告

到達刊登序列中介服務鏈中的自訂事件委刊項時， 系統會對您的類別名稱呼叫 loadRewardedAd() 方法 會在 事件。在本例中 該方法位於 SampleCustomEvent 中，然後會呼叫 loadRewardedAd() SampleRewardedCustomEventLoader 中的方法。

如要提出獎勵廣告要求，請建立或修改可將 Adapter 擴充至 實作 loadRewardedAd()。此外，請建立要實作的新類別 MediationRewardedAd。

在自訂事件範例中 SampleCustomEvent 會擴充 Adapter 類別，然後委派給 SampleRewardedCustomEventLoader。

Java

package com.google.ads.mediation.sample.customevent;

import com.google.android.gms.ads.mediation.Adapter;
import com.google.android.gms.ads.mediation.MediationRewardedAdConfiguration;
import com.google.android.gms.ads.mediation.MediationAdConfiguration;
import com.google.android.gms.ads.mediation.MediationAdLoadCallback;
import com.google.android.gms.ads.mediation.MediationRewardedAd;
import com.google.android.gms.ads.mediation.MediationRewardedAdCallback;
...

public class SampleCustomEvent extends Adapter {

  private SampleNativeCustomEventLoader nativeLoader;

  @Override
  public void loadRewardedAd(
      @NonNull MediationRewardedAdConfiguration mediationRewardedAdConfiguration,
      @NonNull
          MediationAdLoadCallback<MediationRewardedAd, MediationRewardedAdCallback>
              mediationAdLoadCallback) {
    rewardedLoader =
        new SampleRewardedCustomEventLoader(
            mediationRewardedAdConfiguration, mediationAdLoadCallback);
    rewardedLoader.loadAd();
  }
}

SampleRewardedCustomEventLoader 負責下列工作：

  • 載入獎勵廣告

  • 實作 MediationRewardedAd 介面。

  • 接收並回報 Google Mobile Ads SDK 的廣告事件回呼

在 Ad Manager UI 中定義的選用參數是 加進廣告設定中參數可以透過 adConfiguration.getServerParameters().getString(MediationConfiguration.CUSTOM_EVENT_SERVER_PARAMETER_FIELD)。 這個參數通常是廣告聯播網 SDK 提供的廣告單元 ID 需要建立廣告物件的例項。

Java

package com.google.ads.mediation.sample.customevent;

import com.google.android.gms.ads.mediation.Adapter;
import com.google.android.gms.ads.mediation.MediationRewardedAdConfiguration;
import com.google.android.gms.ads.mediation.MediationAdLoadCallback;
import com.google.android.gms.ads.mediation.MediationRewardedAd;
import com.google.android.gms.ads.mediation.MediationRewardedAdCallback;
...

public class SampleRewardedCustomEventLoader extends SampleRewardedAdListener
    implements MediationRewardedAd {

  /** Configuration for requesting the rewarded ad from the third-party network. */
  private final MediationRewardedAdConfiguration mediationRewardedAdConfiguration;

  /**
   * A {@link MediationAdLoadCallback} that handles any callback when a Sample
   * rewarded ad finishes loading.
   */
  private final MediationAdLoadCallback<MediationRewardedAd, MediationRewardedAdCallback>
      mediationAdLoadCallback;

  /** Callback for rewarded ad events. */
  private MediationRewardedAdCallback rewardedAdCallback;

  /** Constructor. */
  public SampleRewardedCustomEventLoader(
      @NonNull MediationRewardedAdConfiguration mediationRewardedAdConfiguration,
      @NonNull MediationAdLoadCallback<MediationRewardedAd, MediationRewardedAdCallback>
              mediationAdLoadCallback) {
    this.mediationRewardedAdConfiguration = mediationRewardedAdConfiguration;
    this.mediationAdLoadCallback = mediationAdLoadCallback;
  }

  /** Loads the rewarded ad from the third-party ad network. */
  public void loadAd() {
    // All custom events have a server parameter named "parameter" that returns
    // back the parameter entered into the AdMob UI when defining the custom event.
    Log.i("RewardedCustomEvent", "Begin loading rewarded ad.");
    String serverParameter = mediationRewardedAdConfiguration
        .getServerParameters()
        .getString(MediationConfiguration
        .CUSTOM_EVENT_SERVER_PARAMETER_FIELD);
    Log.d("RewardedCustomEvent", "Received server parameter.");
    SampleAdRequest request = createSampleRequest(mediationRewardedAdConfiguration);
    sampleRewardedAd = new SampleRewardedAd(serverParameter);
    sampleRewardedAd.setListener(this);
    Log.i("RewardedCustomEvent", "Start fetching rewarded ad.");
    sampleRewardedAd.loadAd(request);
  }

  public SampleAdRequest createSampleRequest(
      MediationAdConfiguration mediationAdConfiguration) {
    SampleAdRequest request = new SampleAdRequest();
    request.setTestMode(mediationAdConfiguration.isTestRequest());
    request.setKeywords(mediationAdConfiguration.getMediationExtras().keySet());
    return request;
  }
}

視廣告是否成功擷取或發生錯誤而定 會將 onSuccess()敬上 或 onFailure()。 系統會透過傳入實作的類別執行個體，呼叫 onSuccess() MediationRewardedAd。

通常，這些方法是在來自 您的轉接程式導入的第三方 SDK。在這個範例中 具有包含相關回呼的 SampleAdListener：

Java

@Override
public void onRewardedAdLoaded() {
  rewardedAdCallback = mediationAdLoadCallback.onSuccess(this);
}

@Override
public void onRewardedAdFailedToLoad(SampleErrorCode errorCode) {
    mediationAdLoadCallback.onFailure(SampleCustomEventError.createSampleSdkError(errorCode));
}

MediationRewardedAd 必須實作 showAd() 方法才能顯示 ：

Java

@Override
public void showAd(Context context) {
  if (!(context instanceof Activity)) {
    rewardedAdCallback.onAdFailedToShow(
        SampleCustomEventError.createCustomEventNoActivityContextError());
    return;
  }
  Activity activity = (Activity) context;

  if (!sampleRewardedAd.isAdAvailable()) {
    rewardedAdCallback.onAdFailedToShow(
        SampleCustomEventError.createCustomEventAdNotAvailableError());
    return;
  }
  sampleRewardedAd.showAd(activity);
}

將中介服務事件轉送至 Google Mobile Ads SDK

呼叫 onSuccess() 後，傳回的 MediationRewardedAdCallback 即可讓轉接程式使用從 第三方 SDK 整合 Google Mobile Ads SDK。 SampleRewardedCustomEventLoader 類別會擴充 SampleAdListener 介面，可從範例廣告聯播網將回呼轉送至 Google 行動服務 廣告 SDK。

請務必讓自訂事件盡可能順利轉送這些回呼，例如： ，讓應用程式從 Google Play 遊戲收到這些對等事件 Mobile Ads SDK以下是回呼的使用範例：

Java

@Override
public void onAdRewarded(final String rewardType, final int amount) {
  RewardItem rewardItem =
      new RewardItem() {
        @Override
        public String getType() {
          return rewardType;
        }

        @Override
        public int getAmount() {
          return amount;
        }
      };
  rewardedAdCallback.onUserEarnedReward(rewardItem);
}

@Override
public void onAdClicked() {
  rewardedAdCallback.reportAdClicked();
}

@Override
public void onAdFullScreen() {
  rewardedAdCallback.onAdOpened();
  rewardedAdCallback.onVideoStart();
  rewardedAdCallback.reportAdImpression();
}

@Override
public void onAdClosed() {
  rewardedAdCallback.onAdClosed();
}

@Override
public void onAdCompleted() {
  rewardedAdCallback.onVideoComplete();
}

這樣就能完成獎勵廣告的自訂事件導入。完整 範例提供 GitHub。 您可以搭配目前支援的廣告聯播網使用，也可以將其修改為 顯示自訂事件獎勵廣告。
