載入單一插頁式廣告

插頁式廣告會全螢幕顯示，覆蓋整個應用程式介面。這類廣告會顯示在應用程式的自然轉換點，例如操作後的空檔或遊戲關卡間的暫停時間。

應用程式顯示插頁式廣告時，使用者可以輕觸廣告繼續，或關閉廣告返回應用程式。

本指南說明如何在 Android 應用程式中整合插頁式廣告。

事前準備

繼續操作前，請先完成下列事項：

  • 設定 GMA Next-Gen SDK。
  • 使用測試插頁式廣告單元 ID ca-app-pub-3940256099942544/1033173712。
    • 建構及測試應用程式時，請務必使用測試廣告，而非實際運作中的廣告，如果未使用測試廣告單元 ID，Google 可能會將您的帳戶停權。
    • 發布應用程式前，請將這個 ID 替換成廣告單元 ID。
    • 如要進一步瞭解 GMA Next-Gen SDK 測試廣告，請參閱「啟用測試廣告」。

載入廣告

以下範例會載入單一廣告：

Kotlin

// Load ads after you initialize MobileAds.
InterstitialAd.load(
  AdRequest.Builder(adUnitId).build(),
  object : AdLoadCallback<InterstitialAd> {
    override fun onAdLoaded(ad: InterstitialAd) {
      // Interstitial ad loaded.
      interstitialAd = ad
    }

    override fun onAdFailedToLoad(adError: LoadAdError) {
      // Interstitial ad failed to load.
      Log.e(TAG, "Interstitial ad failed to load: ${adError.message}")
      interstitialAd = null
    }
  },
)

Java

// Load ads after you initialize MobileAds.
InterstitialAd.load(
    new AdRequest.Builder(adUnitId).build(),
    new AdLoadCallback<InterstitialAd>() {
      @Override
      public void onAdLoaded(@NonNull InterstitialAd ad) {
        // Interstitial ad loaded.
        interstitialAd = ad;
      }

      @Override
      public void onAdFailedToLoad(@NonNull LoadAdError adError) {
        // Interstitial ad failed to load.
        Log.e(TAG, "Interstitial ad failed to load: " + adError.getMessage());
        interstitialAd = null;
      }
    });

測試時，請使用測試廣告單元 ID：ca-app-pub-3940256099942544/1033173712。

顯示廣告

如要顯示插頁式廣告，請呼叫 show 方法。

以下範例會顯示廣告：

Kotlin

private fun showAd(interstitialAd: InterstitialAd, activity: Activity) {
  // Show the ad.
  interstitialAd.show(activity)
}

Java

private void showAd(InterstitialAd interstitialAd, Activity activity) {
  // Show the ad.
  interstitialAd.show(activity);
}

監聽廣告事件

顯示廣告前，請先監聽廣告生命週期事件。以下範例說明如何註冊廣告事件的回呼：

Kotlin

// Listen for ad events.
val ad = interstitialAd
if (ad == null) {
  Log.e(TAG, "Interstitial ad is not ready yet.")
  return
}

ad.adEventCallback =
  object : InterstitialAdEventCallback {
    override fun onAdShowedFullScreenContent() {
      // Interstitial ad did show.
    }

    override fun onAdDismissedFullScreenContent() {
      // Interstitial ad did dismiss.
      interstitialAd = null
    }

    override fun onAdFailedToShowFullScreenContent(
      fullScreenContentError: FullScreenContentError
    ) {
      // Interstitial ad failed to show.
      Log.e(TAG, "Interstitial ad failed to show: ${fullScreenContentError.message}")
    }

    override fun onAdImpression() {
      // Interstitial ad did record an impression.
    }

    override fun onAdClicked() {
      // Interstitial ad did record a click.
    }
  }

Java

// Listen for ad events.
if (interstitialAd == null) {
  Log.e(TAG, "Interstitial ad is not ready yet.");
  return;
}

interstitialAd.setAdEventCallback(
    new InterstitialAdEventCallback() {
      @Override
      public void onAdShowedFullScreenContent() {
        // Interstitial ad did show.
      }

      @Override
      public void onAdDismissedFullScreenContent() {
        // Interstitial ad did dismiss.
        interstitialAd = null;
      }

      @Override
      public void onAdFailedToShowFullScreenContent(
          @NonNull FullScreenContentError fullScreenContentError) {
        // Interstitial ad failed to show.
        Log.e(TAG, "Interstitial ad failed to show: " + fullScreenContentError.getMessage());
      }

      @Override
      public void onAdImpression() {
        // Interstitial ad did record an impression.
      }

      @Override
      public void onAdClicked() {
        // Interstitial ad did record a click.
      }
    });
