폭포식 구조 미디에이션 체인에서 맞춤 이벤트 광고 항목에 도달하면 맞춤 이벤트를 만들 때 제공한 클래스 이름에 loadInterstitialAd() 메서드가 호출됩니다. 이 경우 이 메서드는 SampleCustomEvent에 있고 SampleInterstitialCustomEventLoader에서 loadInterstitialAd() 메서드를 호출합니다.
전면 광고를 요청하려면 Adapter를 확장하여 loadInterstitialAd()를 구현하는 클래스를 만들거나 수정하세요. 또한 MediationInterstitialAd를 구현할 새 클래스를 만듭니다.
맞춤 이벤트 예에서 SampleCustomEvent는 Adapter 클래스를 확장한 다음 SampleInterstitialCustomEventLoader에 위임합니다.
Ad Manager UI에 정의된 선택적 매개변수는 광고 구성에 포함됩니다. adConfiguration.getServerParameters().getString(MediationConfiguration.CUSTOM_EVENT_SERVER_PARAMETER_FIELD)를 통해 매개변수에 액세스할 수 있습니다.
이 매개변수는 일반적으로 광고 네트워크 SDK가 광고 객체를 인스턴스화할 때 요구하는 광고 단위 식별자입니다.
onSuccess()가 호출되면 어댑터가 반환된 MediationInterstitialAdCallback 객체를 사용하여 프레젠테이션 이벤트를 서드 파티 SDK에서 Google 모바일 광고 SDK로 전달할 수 있습니다. SampleInterstitialCustomEventLoader 클래스는 SampleAdListener 인터페이스를 확장하여 샘플 광고 네트워크의 콜백을 Google 모바일 광고 SDK에 전달합니다.
맞춤 이벤트가 이러한 콜백을 최대한 많이 전달하여 앱이 Google 모바일 광고 SDK에서 동등한 이벤트를 수신하도록 하는 것이 중요합니다. 다음은 콜백을 사용하는 방법의 예시입니다.

This loader uses `MediationAdLoadCallback` to report success or failure via `onSuccess()` or `onFailure()`. The `MediationInterstitialAd` must implement a `showAd()` method. The `MediationInterstitialAdCallback` forwards ad events to the Google Mobile Ads SDK.\n"],null,["Prerequisites\n\nComplete the [custom events setup](/ad-manager/mobile-ads-sdk/android/custom-events/setup).\n\nRequest an interstitial ad\n\nWhen the custom event line item is reached in the waterfall mediation chain,\nthe `loadInterstitialAd()` method is called on the class name you provided when\n[creating a custom\nevent](/ad-manager/mobile-ads-sdk/android/custom-events/setup#create). In this case,\nthat method is in `SampleCustomEvent`, which then calls the\n`loadInterstitialAd()` method in `SampleInterstitialCustomEventLoader`.\n\nTo request an interstitial ad, create or modify a class that extends `Adapter`\nto implement `loadInterstitialAd()`. Additionally, create a new class to\nimplement `MediationInterstitialAd`.\n\nIn our [custom event example](//github.com/googleads/googleads-mobile-android-mediation/blob/main/Example/customevent/src/main/java/com/google/ads/mediation/sample/customevent/SampleCustomEvent.java),\n`SampleCustomEvent` extends the `Adapter` class and then delegates to\n`SampleInterstitialCustomEventLoader`. \n\nJava \n\n```java\npackage com.google.ads.mediation.sample.customevent;\n\nimport com.google.android.gms.ads.mediation.Adapter;\nimport com.google.android.gms.ads.mediation.MediationAdConfiguration;\nimport com.google.android.gms.ads.mediation.MediationAdLoadCallback;\nimport com.google.android.gms.ads.mediation.MediationInterstitialAd;\nimport com.google.android.gms.ads.mediation.MediationInterstitialAdCallback;\n...\n\npublic class SampleCustomEvent extends Adapter {\n private SampleInterstitialCustomEventLoader interstitialLoader;\n @Override\n public void loadInterstitialAd(\n @NonNull MediationInterstitialAdConfiguration adConfiguration,\n @NonNull\n MediationAdLoadCallback\u003cMediationInterstitialAd, MediationInterstitialAdCallback\u003e\n callback) {\n interstitialLoader = new SampleInterstitialCustomEventLoader(adConfiguration, callback);\n interstitialLoader.loadAd();\n }\n}\n```\n\n`SampleInterstitialCustomEventLoader` is responsible for the following tasks:\n\n- Loading the interstitial ad and invoking a\n [`MediationAdLoadCallback`](/ad-manager/mobile-ads-sdk/android/reference/com/google/android/gms/ads/mediation/MediationAdLoadCallback)\n method once loading completes.\n\n- Implementing the `MediationInterstitialAd` interface.\n\n- Receiving and reporting ad event callbacks to Google Mobile Ads SDK.\n\nThe optional parameter defined in the Ad Manager UI is\nincluded in the ad configuration. The parameter can be accessed through\n`adConfiguration.getServerParameters().getString(MediationConfiguration.CUSTOM_EVENT_SERVER_PARAMETER_FIELD)`.\nThis parameter is typically an ad unit identifier that an ad network SDK\nrequires when instantiating an ad object. \n\nJava \n\n```java\npackage com.google.ads.mediation.sample.customevent;\n\nimport com.google.android.gms.ads.mediation.Adapter;\nimport com.google.android.gms.ads.mediation.MediationInterstitialAdConfiguration;\nimport com.google.android.gms.ads.mediation.MediationAdLoadCallback;\nimport com.google.android.gms.ads.mediation.MediationInterstitialAd;\nimport com.google.android.gms.ads.mediation.MediationInterstitialAdCallback;\n...\n\npublic class SampleInterstitialCustomEventLoader extends SampleAdListener\n implements MediationInterstitialAd {\n\n /** A sample third-party SDK interstitial ad. */\n private SampleInterstitial sampleInterstitialAd;\n\n /** Configuration for requesting the interstitial ad from the third-party network. */\n private final MediationInterstitialAdConfiguration mediationInterstitialAdConfiguration;\n\n /** Callback for interstitial ad events. */\n private MediationInterstitialAdCallback interstitialAdCallback;\n\n /** Callback that fires on loading success or failure. */\n private final MediationAdLoadCallback\u003cMediationInterstitialAd, MediationInterstitialAdCallback\u003e\n mediationAdLoadCallback;\n\n /** Constructor. */\n public SampleInterstitialCustomEventLoader(\n @NonNull MediationInterstitialAdConfiguration mediationInterstitialAdConfiguration,\n @NonNull MediationAdLoadCallback\u003cMediationInterstitialAd, MediationInterstitialAdCallback\u003e\n mediationAdLoadCallback) {\n this.mediationInterstitialAdConfiguration = mediationInterstitialAdConfiguration;\n this.mediationAdLoadCallback = mediationAdLoadCallback;\n }\n\n /** Loads the interstitial ad from the third-party ad network. */\n public void loadAd() {\n // All custom events have a server parameter named \"parameter\" that returns\n // back the parameter entered into the UI when defining the custom event.\n Log.i(\"InterstitialCustomEvent\", \"Begin loading interstitial ad.\");\n String serverParameter = mediationInterstitialAdConfiguration.getServerParameters().getString(\n MediationConfiguration.CUSTOM_EVENT_SERVER_PARAMETER_FIELD);\n Log.d(\"InterstitialCustomEvent\", \"Received server parameter.\");\n\n sampleInterstitialAd =\n new SampleInterstitial(mediationInterstitialAdConfiguration.getContext());\n sampleInterstitialAd.setAdUnit(serverParameter);\n\n // Implement a SampleAdListener and forward callbacks to mediation.\n sampleInterstitialAd.setAdListener(this);\n\n // Make an ad request.\n Log.i(\"InterstitialCustomEvent\", \"start fetching interstitial ad.\");\n sampleInterstitialAd.fetchAd(\n SampleCustomEvent.createSampleRequest(mediationInterstitialAdConfiguration));\n }\n\npublic SampleAdRequest createSampleRequest(\n MediationAdConfiguration mediationAdConfiguration) {\n SampleAdRequest request = new SampleAdRequest();\n request.setTestMode(mediationAdConfiguration.isTestRequest());\n request.setKeywords(mediationAdConfiguration.getMediationExtras().keySet());\n return request;\n }\n}\n```\n\nDepending on whether the ad is successfully fetched or encounters an error, you\nwould call either\n[`onSuccess()`](/ad-manager/mobile-ads-sdk/android/reference/com/google/android/gms/ads/mediation/MediationAdLoadCallback#onSuccess(MediationAdT))\nor\n[`onFailure()`](/ad-manager/mobile-ads-sdk/android/reference/com/google/android/gms/ads/mediation/MediationAdLoadCallback#onFailure(com.google.android.gms.ads.AdError)).\n`onSuccess()` is called by passing in an instance of the class that implements\n`MediationInterstitialAd`.\n\nTypically, these methods are implemented inside callbacks from the\nthird-party SDK your adapter implements. For this example, the Sample SDK\nhas a `SampleAdListener` with relevant callbacks: \n\nJava \n\n```java\n@Override\npublic void onAdFetchSucceeded() {\n interstitialAdCallback = mediationAdLoadCallback.onSuccess(this);\n}\n\n@Override\npublic void onAdFetchFailed(SampleErrorCode errorCode) {\n mediationAdLoadCallback.onFailure(SampleCustomEventError.createSampleSdkError(errorCode));\n}\n```\n\n`MediationInterstitialAd` requires implementing a `showAd()` method to display\nthe ad: \n\nJava \n\n```java\n@Override\npublic void showAd(@NonNull Context context) {\n sampleInterstitialAd.show();\n}\n```\n\nForward mediation events to Google Mobile Ads SDK\n\nOnce `onSuccess()` is called, the returned `MediationInterstitialAdCallback`\nobject can then be used by the adapter to forward presentation events from the\nthird-party SDK to Google Mobile Ads SDK. The\n`SampleInterstitialCustomEventLoader` class extends the `SampleAdListener`\ninterface to forward callbacks from the sample ad network to the Google Mobile\nAds SDK.\n\nIt's important that your custom event forwards as many of these callbacks as\npossible, so that your app receives these equivalent events from the Google\nMobile Ads SDK. Here's an example of using callbacks: \n\nJava \n\n```java\n@Override\npublic void onAdFullScreen() {\n interstitialAdCallback.reportAdImpression();\n interstitialAdCallback.onAdOpened();\n}\n\n@Override\npublic void onAdClosed() {\n interstitialAdCallback.onAdClosed();\n}\n```\n\nThis completes the custom events implementation for interstitial ads. The full\nexample is available on\n[GitHub](//github.com/googleads/googleads-mobile-android-mediation/tree/master/Example/customevent/src/main/java/com/google/ads/mediation/sample/customevent).\nYou can use it with an ad network that is already supported or modify it to\ndisplay custom event interstitial ads."]]
