插頁式獎勵廣告 (Beta 版)

插頁式獎勵廣告是一種 一種獎勵廣告格式，可讓你在放送的廣告中向使用者提供獎勵 自動在應用程式的自然轉換期間自動切換。有別於獎勵廣告 必須啟用才能觀看插頁式獎勵廣告。

必要條件

* Google Mobile Ads SDK 19.2.0 以上版本。

導入作業

整合插頁式獎勵廣告的主要步驟如下：

  • 載入廣告
  • 註冊全螢幕事件回呼
  • 處理獎勵回呼
  • 顯示廣告

載入廣告

系統會使用靜態 load() 方法，完成載入廣告 RewardedInterstitialAd 類別。載入方法需要背景資訊 單位 ID、AdManagerAdRequest 物件和 RewardedInterstitialAdLoadCallback，以便於廣告載入成功時收到通知，或 失敗。所載入的 RewardedInterstitialAd 物件會以參數的形式提供，該物件位於 onRewardedInterstitialAdLoaded() 回呼。

以下範例說明如何在 MainActivity 中載入 RewardedInterstitialAd。

Java

public class MainActivity extends AppCompatActivity {
  private RewardedInterstitialAd rewardedInterstitialAd;
  private String TAG = "MainActivity";

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    new Thread(
            () -> {
              // Initialize the Google Mobile Ads SDK on a background thread.
              MobileAds.initialize(this, initializationStatus -> {});
              // Load an ad on the main thread.
              runOnUiThread(
                  () -> {
                    loadAd();
                  });
            })
        .start();
  }

  public void loadAd() {
    // Use the test ad unit ID to load an ad.
    RewardedInterstitialAd.load(MainActivity.this, "/21775744923/example/rewarded-interstitial",
        new AdManagerAdRequest.Builder().build(),  new RewardedInterstitialAdLoadCallback() {
      @Override
      public void onAdLoaded(RewardedInterstitialAd ad) {
        Log.d(TAG, "Ad was loaded.");
        rewardedInterstitialAd = ad;
      }
      @Override
      public void onAdFailedToLoad(LoadAdError loadAdError) {
        Log.d(TAG, loadAdError.toString());
        rewardedInterstitialAd = null;
      }
    });
  }
}

Kotlin

import com.google.android.gms.ads.rewardedinterstitial.RewardedInterstitialAd
import com.google.android.gms.ads.rewardedinterstitial.RewardedInterstitialAdLoadCallback

class MainActivity : AppCompactActivity() {

  private var rewardedInterstitialAd? = null
  private final var TAG = "MainActivity"

  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    val backgroundScope = CoroutineScope(Dispatchers.IO)
    backgroundScope.launch {
      // Initialize the Google Mobile Ads SDK on a background thread.
      MobileAds.initialize(this@MainActivity) {}
      // Load an ad on the main thread.
      runOnUiThread {
        loadAd()
      }
    }
  }

  private fun loadAd() {
    RewardedInterstitialAd.load(this, "/21775744923/example/rewarded-interstitial",
      AdManagerAdRequest.Builder().build(), object : RewardedInterstitialAdLoadCallback() {
      override fun onAdLoaded(ad: RewardedInterstitialAd) {
        Log.d(TAG, "Ad was loaded.")
        rewardedInterstitialAd = ad
      }

      override fun onAdFailedToLoad(adError: LoadAdError) {
        Log.d(TAG, adError?.toString())
        rewardedInterstitialAd = null
      }
    })
  }
}

註冊回呼

若要收到簡報活動的通知，您必須傳遞 FullScreenContentCallback 物件設定為廣告的 setter。 FullScreenContentCallback 物件會處理廣告顯示時的回呼 成功或失敗，並在關閉時關閉以下程式碼 說明如何在 BigQuery 中設定匿名 FullScreenContentCallback 物件 RewardedInterstitialAdLoadCallback:

Java

public void loadAd(){
  RewardedInterstitialAd.load(MainActivity.this, "/21775744923/example/rewarded-interstitial",
      new AdManagerAdRequest.Builder().build(), new RewardedInterstitialAdLoadCallback() {
    @Override
    public void onAdLoaded(RewardedInterstitialAd ad) {
      rewardedInterstitialAd = ad;
      rewardedInterstitialAd.setFullScreenContentCallback(new FullScreenContentCallback() {
        @Override
        public void onAdClicked() {
          // Called when a click is recorded for an ad.
          Log.d(TAG, "Ad was clicked.");
        }

        @Override
        public void onAdDismissedFullScreenContent() {
          // Called when ad is dismissed.
          // Set the ad reference to null so you don't show the ad a second time.
          Log.d(TAG, "Ad dismissed fullscreen content.");
          rewardedInterstitialAd = null;
        }

        @Override
        public void onAdFailedToShowFullScreenContent(AdError adError) {
          // Called when ad fails to show.
          Log.e(TAG, "Ad failed to show fullscreen content.");
          rewardedInterstitialAd = null;
        }

        @Override
        public void onAdImpression() {
          // Called when an impression is recorded for an ad.
          Log.d(TAG, "Ad recorded an impression.");
        }

        @Override
        public void onAdShowedFullScreenContent() {
          // Called when ad is shown.
          Log.d(TAG, "Ad showed fullscreen content.");
        }
      });
    }
    @Override
    public void onAdFailedToLoad(LoadAdError loadAdError) {
      Log.d(TAG, loadAdError.toString());
      rewardedInterstitialAd = null;
    }
  });
}

Kotlin

private fun loadAd() {
  RewardedInterstitialAd.load(this, "/21775744923/example/rewarded-interstitial",
    AdManagerAdRequest.Builder().build(), object : RewardedInterstitialAdLoadCallback() {
    override fun onAdLoaded(ad: RewardedInterstitialAd) {
      rewardedInterstitialAd = ad
      rewardedInterstitialAd?.fullScreenContentCallback = object: FullScreenContentCallback() {
        override fun onAdClicked() {
          // Called when a click is recorded for an ad.
          Log.d(TAG, "Ad was clicked.")
        }

        override fun onAdDismissedFullScreenContent() {
          // Called when ad is dismissed.
          // Set the ad reference to null so you don't show the ad a second time.
          Log.d(TAG, "Ad dismissed fullscreen content.")
          rewardedInterstitialAd = null
        }

        override fun onAdFailedToShowFullScreenContent(adError: AdError) {
          // Called when ad fails to show.
          Log.e(TAG, "Ad failed to show fullscreen content.")
          rewardedInterstitialAd = null
        }

        override fun onAdImpression() {
          // Called when an impression is recorded for an ad.
          Log.d(TAG, "Ad recorded an impression.")
        }

        override fun onAdShowedFullScreenContent() {
          // Called when ad is shown.
          Log.d(TAG, "Ad showed fullscreen content.")
        }
      }
    }

    override fun onAdFailedToLoad(adError: LoadAdError) {
      Log.d(TAG, adError?.toString())
      rewardedInterstitialAd = null
    }
  })
}

處理獎勵

如要顯示插頁式獎勵廣告，請在 MainActivity 中導入 OnUserEarnedRewardListener 介面，以便在使用者獲得獎勵時收到通知。

Java

public class MainActivity extends AppCompatActivity implements OnUserEarnedRewardListener {
  ...
  @Override
  public void onUserEarnedReward(@NonNull RewardItem rewardItem) {
    Log.i(TAG, "User earned reward.");
    // TODO: Reward the user!
  }
}

Kotlin

class MainActivity : AppCompatActivity(), OnUserEarnedRewardListener {
  ...
  override fun onUserEarnedReward(rewardItem: RewardItem) {
    Log.d(TAG, "User earned reward.")
    // TODO: Reward the user!
  }
}

放送廣告

實作 OnUserEarnedRewardListener 介面後，您可以使用廣告的 show() 方法呈現廣告，如下所示：

Java

rewardedInterstitialAd.show(/* Activity */ MainActivity.this,/*
    OnUserEarnedRewardListener */ MainActivity.this);

Kotlin

rewardedInterstitialAd?.show(/* Activity */ this, /*
    OnUserEarnedRewardListener */ this)
