맞춤 탭 최적화

광고용 웹 뷰 API를 사용하면 CustomTabSession의 태그에서 앱 신호를 사용할 수 있으므로 콘텐츠를 제공한 웹 게시자의 수익 창출을 개선하고 광고주를 스팸으로부터 보호할 수 있습니다.

작동 방식

Google 모바일 광고 SDK (베타)와의 통신은 다음 중 하나에 의해 트리거된 광고 이벤트에 대한 응답으로만 발생합니다.

Google 모바일 광고 SDK (베타)는 Android 프레임워크에서 제공하는 CustomTabsSession과의 postMessage 채널을 열어 통신을 지원합니다.

기본 요건

SDK에 애플리케이션 ID 전달하기

Ad Manager 애플리케이션 ID가 이미 있는 경우 Google 모바일 광고 SDK (베타)를 기존 애플리케이션 ID로 초기화합니다.

Ad Manager 애플리케이션 ID가 없는 경우 Google 모바일 광고 SDK (베타)를 초기화할 때 InitializationConfig.WEBVIEW_APIS_FOR_ADS_APPLICATION_ID를 애플리케이션 ID로 전달합니다.

Kotlin

MobileAds.initialize(
    this@MainActivity,
    // Use this application ID to initialize the Google Mobile Ads SDK (beta) if
    // you don't have an Ad Manager application ID.
    InitializationConfig.Builder(InitializationConfig.WEBVIEW_APIS_FOR_ADS_APPLICATION_ID)
        .build(),
  ) {
    // Adapter initialization complete.
  }

자바

MobileAds.initialize(
    this,
    // Use this application ID to initialize the Google Mobile Ads SDK (beta) if
    // you don't have an Ad Manager application ID.
    new InitializationConfig.Builder(InitializationConfig.WEBVIEW_APIS_FOR_ADS_APPLICATION_ID)
        .build(),
        initializationStatus -> {
          // Adapter initialization is complete.
          });

구현

Chrome 맞춤 탭 구현 내에서 onCustomTabsServiceConnected() 콜백의 코드를 수정합니다. newSession()을 MobileAds.registerCustomTabsSession()으로 바꿉니다. 이렇게 하면 postMessage 채널과의 연결이 설정되어 SDK 신호로 광고 태그를 보강할 수 있습니다. postMessage 채널을 연결하려면 디지털 애셋 링크가 필요합니다. 원하는 경우 CustomTabsCallback 매개변수를 설정하여 Chrome 맞춤 탭 이벤트를 수신 대기할 수 있습니다.

여전히 Google 모바일 광고 SDK (베타)에서 수신한 CustomTabsSession에서 메시지를 전송할 수 있지만 SDK에서 기존 채널을 재정의하는 새 채널을 요청하면 포트가 변경될 수 있습니다.

다음 코드 스니펫은 Google 모바일 광고 SDK (베타)를 사용하여 CustomTabsSession을 등록하는 방법을 보여줍니다.
