插頁式獎勵廣告

「插頁式獎勵廣告」是一種獎勵廣告格式,可讓您針對在應用程式自然轉換時自動顯示的廣告提供獎勵。與獎勵廣告不同的是,使用者不需要選擇觀看插頁式獎勵廣告。

必要條件

  • Google Mobile Ads SDK 19.2.0 以上版本。
  • 按照入門指南匯入 Google Mobile Ads SDK,並更新您的 AndroidManifest.xml
  • 如要放送插頁式獎勵廣告,請與您的客戶經理聯絡。

導入作業

導入插頁式獎勵廣告的主要步驟如下:

  1. 載入廣告。
  2. 註冊全螢幕事件回呼。
  3. 處理獎勵回呼。
  4. 顯示廣告。

載入廣告

廣告載入是在 RewardedInterstitialAd 類別的靜態 load() 方法完成。載入方法需要結構定義、廣告單元 ID、 an AdRequest 物件和 RewardedInterstitialAdLoadCallback,以便在廣告成功或失敗時收到通知。載入的 RewardedInterstitialAd 物件會以 onRewardedInterstitialAdLoaded() 回呼中的參數的形式提供。以下範例顯示如何在 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);

    MobileAds.initialize(this, new OnInitializationCompleteListener() {
      @Override
      public void onInitializationComplete(InitializationStatus initializationStatus) {
        loadAd();
      }
    });
  }

  public void loadAd() {
    // Use the test ad unit ID to load an ad.
    RewardedInterstitialAd.load(MainActivity.this, "ca-app-pub-3940256099942544/5354046379",
        new AdRequest.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)

    MobileAds.initialize(this) { initializationStatus ->
      loadAd()
    }
  }

  private fun loadAd() {
    RewardedInterstitialAd.load(this, "ca-app-pub-3940256099942544/5354046379",
      AdRequest.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

如要接收簡報事件的通知,您必須將 FullScreenContentCallback 物件傳送至廣告的設定器。FullScreenContentCallback 物件會處理廣告成功或失敗的回呼,以及廣告關閉的時間。下列程式碼顯示如何在 RewardedInterstitialAdLoadCallback 中設定匿名的 FullScreenContentCallback 物件:

Java

public void loadAd(){
  RewardedInterstitialAd.load(MainActivity.this, "ca-app-pub-3940256099942544/5354046379",
      new AdRequest.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, "ca-app-pub-3940256099942544/5354046379",
    AdRequest.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接收通知。

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!
  }
}

顯示廣告

導入 OnUserEarnedRewardListener 介面後,您就能使用廣告的 show() 方法顯示廣告,如下所示:

Java

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

Kotlin

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