폭포식 구조 미디에이션 체인에서 맞춤 이벤트 광고 항목에 도달하면 맞춤 이벤트를 만들 때 제공한 클래스 이름에 loadRewardedAd() 메서드가 호출됩니다. 이 경우 이 메서드는 SampleCustomEvent에 있고 SampleRewardedCustomEventLoader에서 loadRewardedAd() 메서드를 호출합니다.
보상형 광고를 요청하려면 Adapter를 확장하여 loadRewardedAd()를 구현하는 클래스를 만들거나 수정하세요. 또한 MediationRewardedAd를 구현할 새 클래스를 만듭니다.
맞춤 이벤트 예에서 SampleCustomEvent는 Adapter 클래스를 확장한 다음 SampleRewardedCustomEventLoader에 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 MediationRewardedAdCallback 객체를 사용하여 프레젠테이션 이벤트를 서드 파티 SDK에서 Google 모바일 광고 SDK로 전달할 수 있습니다. SampleRewardedCustomEventLoader 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.

In this case,\nthat method is in `SampleCustomEvent`, which then calls the `loadRewardedAd()`\nmethod in `SampleRewardedCustomEventLoader`.\n\nTo request a rewarded ad, create or modify a class that extends `Adapter` to\nimplement `loadRewardedAd()`. Additionally, create a new class to implement\n`MediationRewardedAd`.\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`SampleRewardedCustomEventLoader`. \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.MediationRewardedAdConfiguration;\nimport com.google.android.gms.ads.mediation.MediationAdConfiguration;\nimport com.google.android.gms.ads.mediation.MediationAdLoadCallback;\nimport com.google.android.gms.ads.mediation.MediationRewardedAd;\nimport com.google.android.gms.ads.mediation.MediationRewardedAdCallback;\n...\n\npublic class SampleCustomEvent extends Adapter {\n\n private SampleNativeCustomEventLoader nativeLoader;\n\n @Override\n public void loadRewardedAd(\n @NonNull MediationRewardedAdConfiguration mediationRewardedAdConfiguration,\n @NonNull\n MediationAdLoadCallback\u003cMediationRewardedAd, MediationRewardedAdCallback\u003e\n mediationAdLoadCallback) {\n rewardedLoader =\n new SampleRewardedCustomEventLoader(\n mediationRewardedAdConfiguration, mediationAdLoadCallback);\n rewardedLoader.loadAd();\n }\n}\n```\n\n`SampleRewardedCustomEventLoader` is responsible for the following tasks:\n\n- Loading the rewarded ad\n\n- Implementing the `MediationRewardedAd` 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.MediationRewardedAdConfiguration;\nimport com.google.android.gms.ads.mediation.MediationAdLoadCallback;\nimport com.google.android.gms.ads.mediation.MediationRewardedAd;\nimport com.google.android.gms.ads.mediation.MediationRewardedAdCallback;\n...\n\npublic class SampleRewardedCustomEventLoader extends SampleRewardedAdListener\n implements MediationRewardedAd {\n\n /** Configuration for requesting the rewarded ad from the third-party network. */\n private final MediationRewardedAdConfiguration mediationRewardedAdConfiguration;\n\n /**\n * A {@link MediationAdLoadCallback} that handles any callback when a Sample\n * rewarded ad finishes loading.\n */\n private final MediationAdLoadCallback\u003cMediationRewardedAd, MediationRewardedAdCallback\u003e\n mediationAdLoadCallback;\n\n /** Callback for rewarded ad events. */\n private MediationRewardedAdCallback rewardedAdCallback;\n\n /** Constructor. */\n public SampleRewardedCustomEventLoader(\n @NonNull MediationRewardedAdConfiguration mediationRewardedAdConfiguration,\n @NonNull MediationAdLoadCallback\u003cMediationRewardedAd, MediationRewardedAdCallback\u003e\n mediationAdLoadCallback) {\n this.mediationRewardedAdConfiguration = mediationRewardedAdConfiguration;\n this.mediationAdLoadCallback = mediationAdLoadCallback;\n }\n\n /** Loads the rewarded 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 AdMob UI when defining the custom event.\n Log.i(\"RewardedCustomEvent\", \"Begin loading rewarded ad.\");\n String serverParameter = mediationRewardedAdConfiguration\n .getServerParameters()\n .getString(MediationConfiguration\n .CUSTOM_EVENT_SERVER_PARAMETER_FIELD);\n Log.d(\"RewardedCustomEvent\", \"Received server parameter.\");\n SampleAdRequest request = createSampleRequest(mediationRewardedAdConfiguration);\n sampleRewardedAd = new SampleRewardedAd(serverParameter);\n sampleRewardedAd.setListener(this);\n Log.i(\"RewardedCustomEvent\", \"Start fetching rewarded ad.\");\n sampleRewardedAd.loadAd(request);\n }\n\n public 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`MediationRewardedAd`.\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 onRewardedAdLoaded() {\n rewardedAdCallback = mediationAdLoadCallback.onSuccess(this);\n}\n\n@Override\npublic void onRewardedAdFailedToLoad(SampleErrorCode errorCode) {\n mediationAdLoadCallback.onFailure(SampleCustomEventError.createSampleSdkError(errorCode));\n}\n```\n\n`MediationRewardedAd` requires implementing a `showAd()` method to display\nthe ad: \n\nJava \n\n```java\n@Override\npublic void showAd(Context context) {\n if (!(context instanceof Activity)) {\n rewardedAdCallback.onAdFailedToShow(\n SampleCustomEventError.createCustomEventNoActivityContextError());\n return;\n }\n Activity activity = (Activity) context;\n\n if (!sampleRewardedAd.isAdAvailable()) {\n rewardedAdCallback.onAdFailedToShow(\n SampleCustomEventError.createCustomEventAdNotAvailableError());\n return;\n }\n sampleRewardedAd.showAd(activity);\n}\n```\n\nForward mediation events to Google Mobile Ads SDK\n\nOnce `onSuccess()` is called, the returned `MediationRewardedAdCallback`\nobject can then be used by the adapter to forward presentation events from the\nthird-party SDK to Google Mobile Ads SDK. The\n`SampleRewardedCustomEventLoader` 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\nGoogle Mobile Ads SDK. Here's an example of using callbacks: \n\nJava \n\n```java\n@Override\npublic void onAdRewarded(final String rewardType, final int amount) {\n RewardItem rewardItem =\n new RewardItem() {\n @Override\n public String getType() {\n return rewardType;\n }\n\n @Override\n public int getAmount() {\n return amount;\n }\n };\n rewardedAdCallback.onUserEarnedReward(rewardItem);\n}\n\n@Override\npublic void onAdClicked() {\n rewardedAdCallback.reportAdClicked();\n}\n\n@Override\npublic void onAdFullScreen() {\n rewardedAdCallback.onAdOpened();\n rewardedAdCallback.onVideoStart();\n rewardedAdCallback.reportAdImpression();\n}\n\n@Override\npublic void onAdClosed() {\n rewardedAdCallback.onAdClosed();\n}\n\n@Override\npublic void onAdCompleted() {\n rewardedAdCallback.onVideoComplete();\n}\n```\n\nThis completes the custom events implementation for rewarded 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 rewarded ads."]]
