獎勵廣告

獎勵廣告 可讓您以應用程式內產品來獎勵使用者 影片廣告、可試玩廣告及問卷調查

必要條件

  • Google Mobile Ads SDK 19.7.0 以上版本。
  • 完成入門指南。

一律使用測試廣告進行測試

建構及測試應用程式時，請務必使用測試廣告，而非 現場及正式環境廣告否則可能導致帳戶遭到停權。

要載入測試廣告，最簡單的方法是使用我們專屬的測試廣告單元編號。 Android 獎勵廣告：

ca-app-pub-3940256099942544/5224354917

這項機制經過特別設定，可針對每個請求傳回測試廣告 在您的程式設計、測試和偵錯時，可以免費使用應用程式。只需製作 務必先用廣告單元 ID 取代廣告單元，再發布應用程式。

若要進一步瞭解 Mobile Ads SDK 測試廣告的運作方式，請參閱「測試 Google Ads。

載入獎勵廣告物件

系統會在以下位置呼叫靜態的 load() 方法，載入獎勵廣告 RewardedAd 類別並傳入 RewardedAdLoadCallback。這通常 透過 Activity 的 onCreate() 方法完成。 請注意，與其他格式載入回呼一樣，RewardedAdLoadCallback 會利用 LoadAdError 提供更精確的錯誤詳細資料。

Java

import com.google.android.gms.ads.rewarded.RewardedAd;

public class MainActivity extends Activity {
  private RewardedAd rewardedAd;
  private final String TAG = "MainActivity";

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    AdRequest adRequest = new AdRequest.Builder().build();
    RewardedAd.load(this, "ca-app-pub-3940256099942544/5224354917",
      adRequest, new RewardedAdLoadCallback() {
        @Override
        public void onAdFailedToLoad(@NonNull LoadAdError loadAdError) {
          // Handle the error.
          Log.d(TAG, loadAdError.toString());
          rewardedAd = null;
        }

        @Override
        public void onAdLoaded(@NonNull RewardedAd ad) {
          rewardedAd = ad;
          Log.d(TAG, "Ad was loaded.");
        }
    });
  }
}

Kotlin

class MainActivity : AppCompatActivity() {

  private var rewardedAd: RewardedAd? = null
  private final var TAG = "MainActivity"

  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)
    var adRequest = AdRequest.Builder().build()
    RewardedAd.load(this,"ca-app-pub-3940256099942544/5224354917", adRequest, object : RewardedAdLoadCallback() {
      override fun onAdFailedToLoad(adError: LoadAdError) {
        Log.d(TAG, adError?.toString())
        rewardedAd = null
      }

      override fun onAdLoaded(ad: RewardedAd) {
        Log.d(TAG, "Ad was loaded.")
        rewardedAd = ad
       }
    })
  }
}

設定 FullScreenContentCallback

FullScreenContentCallback 會處理與顯示 RewardedAd。顯示 RewardedAd 之前，請務必先設定回呼 如下所示：

Java

rewardedAd.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.");
    rewardedAd = null;
  }

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

Kotlin

rewardedAd?.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.")
    rewardedAd = null
  }

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

顯示廣告

顯示獎勵廣告時，您需要使用 OnUserEarnedRewardListener 物件 處理獎勵事件

Java

if (rewardedAd != null) {
  Activity activityContext = MainActivity.this;
  rewardedAd.show(activityContext, new OnUserEarnedRewardListener() {
    @Override
    public void onUserEarnedReward(@NonNull RewardItem rewardItem) {
      // Handle the reward.
      Log.d(TAG, "The user earned the reward.");
      int rewardAmount = rewardItem.getAmount();
      String rewardType = rewardItem.getType();
    }
  });
} else {
  Log.d(TAG, "The rewarded ad wasn't ready yet.");
}

Kotlin

rewardedAd?.let { ad ->
  ad.show(this, OnUserEarnedRewardListener { rewardItem ->
    // Handle the reward.
    val rewardAmount = rewardItem.amount
    val rewardType = rewardItem.type
    Log.d(TAG, "User earned the reward.")
  })
} ?: run {
  Log.d(TAG, "The rewarded ad wasn't ready yet.")
}

[選用] 驗證伺服器端驗證 (SSV) 回呼

需要在伺服器端使用額外資料的應用程式 驗證回呼應使用 獎勵廣告的自訂資料功能。獎勵廣告中設定的任何字串值 系統會將物件傳遞至 SSV 回呼的 custom_data 查詢參數。如果答案為「否」 如果已設定自訂資料值，custom_data 查詢參數將不會 傳遞到 SSV 回呼中。

以下程式碼範例示範如何設定獎勵廣告的自訂資料 物件，再請求廣告。

Java

RewardedAd.load(MainActivity.this, "ca-app-pub-3940256099942544/5354046379",
    new AdRequest.Builder().build(),  new RewardedAdLoadCallback() {
  @Override
  public void onAdLoaded(RewardedAd ad) {
    Log.d(TAG, "Ad was loaded.");
    rewardedAd = ad;
    ServerSideVerificationOptions options = new ServerSideVerificationOptions
        .Builder()
        .setCustomData("SAMPLE_CUSTOM_DATA_STRING")
        .build();
    rewardedAd.setServerSideVerificationOptions(options);
  }
  @Override
  public void onAdFailedToLoad(LoadAdError loadAdError) {
      Log.d(TAG, loadAdError.toString());
      rewardedAd = null;
  }
});

Kotlin

RewardedAd.load(this, "ca-app-pub-3940256099942544/5354046379",
    AdRequest.Builder().build(), object : RewardedAdLoadCallback() {
  override fun onAdLoaded(ad: RewardedAd) {
    Log.d(TAG, "Ad was loaded.")
    rewardedInterstitialAd = ad
    val options = ServerSideVerificationOptions.Builder()
        .setCustomData("SAMPLE_CUSTOM_DATA_STRING")
        .build()
    rewardedAd.setServerSideVerificationOptions(options)
  }

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

如要設定自訂獎勵字串，就必須在顯示 廣告。

常見問題

初始化呼叫是否有逾時？
10 秒後，Google Mobile Ads SDK 會叫用 OnInitializationCompleteListener (即使中介服務聯播網尚未
如果我收到初始化回呼時，有些中介服務聯播網還沒準備就緒，該怎麼辦？

建議您在 OnInitializationCompleteListener。即使中介服務聯播網尚未準備就緒 Google Mobile Ads SDK 仍會要求該聯播網提供廣告。如果 中介服務聯播網在逾時後完成初始化作業，仍可 服務日後的廣告請求

您可以呼叫 MobileAds.getInitializationStatus()，繼續在應用程式工作階段中輪詢所有轉接程式的初始化狀態。

如何找出特定中介服務聯播網未就緒的原因？

AdapterStatus.getDescription() 說明轉接器未準備就緒的原因 服務廣告請求

系統是否一律會先呼叫 onUserEarnedReward() 回呼，再呼叫 onAdDismissedFullScreenContent() 回呼？

Google Ads 的所有 onUserEarnedReward() 呼叫都發生在 onAdDismissedFullScreenContent()。對於透過中介服務放送的廣告，第三方廣告聯播網 SDK 的實作方式會決定回呼順序。廣告聯播網 SDK 提供含獎勵資訊的單一關閉回呼， 中介服務轉接程式會叫用 onUserEarnedReward() onAdDismissedFullScreenContent()。
