插頁式廣告自訂事件

必要條件

完成自訂事件設定

請求插頁式廣告

到達刊登序列中介服務鏈中的自訂事件委刊項時, loadInterstitialAd() 方法會在您提供的類別名稱上呼叫 建立自訂 事件。在本例中 該方法位於 SampleCustomEvent 中,然後呼叫 SampleInterstitialCustomEventLoader 中的 loadInterstitialAd() 方法。

如要請求插頁式廣告,請建立或修改擴充 Adapter 的類別 實作 loadInterstitialAd()。此外,請建立新類別, 實作 MediationInterstitialAd

自訂事件範例SampleCustomEvent 會擴充 Adapter 類別,然後委派給 SampleInterstitialCustomEventLoader

Java

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

import com.google.android.gms.ads.mediation.Adapter;
import com.google.android.gms.ads.mediation.MediationAdConfiguration;
import com.google.android.gms.ads.mediation.MediationAdLoadCallback;
import com.google.android.gms.ads.mediation.MediationInterstitialAd;
import com.google.android.gms.ads.mediation.MediationInterstitialAdCallback;
...

public class SampleCustomEvent extends Adapter {
  private SampleInterstitialCustomEventLoader interstitialLoader;
  @Override
  public void loadInterstitialAd(
      @NonNull MediationInterstitialAdConfiguration adConfiguration,
      @NonNull
          MediationAdLoadCallback<MediationInterstitialAd, MediationInterstitialAdCallback>
              callback) {
    interstitialLoader = new SampleInterstitialCustomEventLoader(adConfiguration, callback);
    interstitialLoader.loadAd();
  }
}

SampleInterstitialCustomEventLoader 負責下列工作:

  • 載入插頁式廣告並叫用 MediationAdLoadCallback敬上 方法。

  • 實作 MediationInterstitialAd 介面。

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

AdMob 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.MediationInterstitialAdConfiguration;
import com.google.android.gms.ads.mediation.MediationAdLoadCallback;
import com.google.android.gms.ads.mediation.MediationInterstitialAd;
import com.google.android.gms.ads.mediation.MediationInterstitialAdCallback;
...

public class SampleInterstitialCustomEventLoader extends SampleAdListener
    implements MediationInterstitialAd {

  /** A sample third-party SDK interstitial ad. */
  private SampleInterstitial sampleInterstitialAd;

  /** Configuration for requesting the interstitial ad from the third-party network. */
  private final MediationInterstitialAdConfiguration mediationInterstitialAdConfiguration;

  /** Callback for interstitial ad events. */
  private MediationInterstitialAdCallback interstitialAdCallback;

  /** Callback that fires on loading success or failure. */
  private final MediationAdLoadCallback<MediationInterstitialAd, MediationInterstitialAdCallback>
      mediationAdLoadCallback;

  /** Constructor. */
  public SampleInterstitialCustomEventLoader(
      @NonNull MediationInterstitialAdConfiguration mediationInterstitialAdConfiguration,
      @NonNull MediationAdLoadCallback<MediationInterstitialAd, MediationInterstitialAdCallback>
              mediationAdLoadCallback) {
    this.mediationInterstitialAdConfiguration = mediationInterstitialAdConfiguration;
    this.mediationAdLoadCallback = mediationAdLoadCallback;
  }

  /** Loads the interstitial 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 UI when defining the custom event.
    Log.i("InterstitialCustomEvent", "Begin loading interstitial ad.");
    String serverParameter = mediationInterstitialAdConfiguration.getServerParameters().getString(
        MediationConfiguration.CUSTOM_EVENT_SERVER_PARAMETER_FIELD);
    Log.d("InterstitialCustomEvent", "Received server parameter.");

    sampleInterstitialAd =
        new SampleInterstitial(mediationInterstitialAdConfiguration.getContext());
    sampleInterstitialAd.setAdUnit(serverParameter);

    // Implement a SampleAdListener and forward callbacks to mediation.
    sampleInterstitialAd.setAdListener(this);

    // Make an ad request.
    Log.i("InterstitialCustomEvent", "start fetching interstitial ad.");
    sampleInterstitialAd.fetchAd(
        SampleCustomEvent.createSampleRequest(mediationInterstitialAdConfiguration));
  }

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()。 方法是傳入實作的類別例項,藉此呼叫 onSuccess() MediationInterstitialAd

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 onAdFetchSucceeded() {
  interstitialAdCallback = mediationAdLoadCallback.onSuccess(this);
}

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

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

Java

@Override
public void showAd(@NonNull Context context) {
  sampleInterstitialAd.show();
}

將中介服務事件轉送至 Google Mobile Ads SDK

呼叫 onSuccess() 後,傳回的 MediationInterstitialAdCallback 即可讓轉接程式使用從 第三方 SDK 整合 Google Mobile Ads SDK。 SampleInterstitialCustomEventLoader 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 onAdFullScreen() {
  interstitialAdCallback.reportAdImpression();
  interstitialAdCallback.onAdOpened();
}

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

這樣就能完成插頁式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 多媒體自訂事件插頁式廣告。
