獎勵廣告

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

打造及測試應用程式時,請務必使用測試廣告,而非實際的廣告。否則帳戶可能會遭到停權。

如要載入測試廣告,最簡單的方法是使用 Android 獎勵廣告專用的測試廣告單元 ID:

ca-app-pub-3940256099942544/5224354917

這個功能經過特別設計,可針對每項要求傳回測試廣告,您可以在編寫、測試及偵錯時,自由在應用程式中使用。您只要在發布應用程式前將其 ID 換成您自己的廣告單元 ID 即可。

載入獎勵廣告物件

呼叫 RewardedAd 類別上的靜態 load() 方法並傳入 RewardedAdLoadCallback 後,即可載入獎勵廣告。這通常位於 ActivityonCreate() 方法中。請注意,如同其他格式載入回呼,RewardedAdLoadCallback 會使用 LoadAdError 提供較高的擬真度錯誤詳細資料。

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
       }
    })
  }
}

[選用] 驗證伺服器端驗證 (SSV) 回呼

如果應用程式需要在伺服器端驗證回呼中提供額外資料,則應使用獎勵廣告的自訂資料功能。系統會將獎勵物件設定的任何字串值傳遞至 SSV 回呼的 custom_data 查詢參數。如未設定自訂資料值,SSV 回呼就不會顯示 custom_data 查詢參數值。

下列程式碼範例示範如何在請求廣告前,為獎勵廣告物件設定自訂資料。

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
  }
})

如果您要設定自訂獎勵字串,則必須先完成設定才能顯示廣告。

設定 FullScreenContentCallback

FullScreenContentCallback 會處理顯示 RewardedAd 的相關事件。在顯示 RewardedAd 之前,請務必設定回呼,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,您將使用 OnUserEarnedRewardListener 物件來處理獎勵事件。

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.")
}

常見問題

初始化呼叫有逾時嗎?
10 秒後,即使中介服務聯播網尚未完成初始化作業,Google Mobile Ads SDK 也會叫用 OnInitializationCompleteListener
如果我收到初始化初始化作業,但部分中介服務聯播網尚未完成,該怎麼辦?

建議您在 OnInitializationCompleteListener 回呼內載入廣告。即使中介服務聯播網尚未準備就緒,Google Mobile Ads SDK 仍會要求該聯播網放送廣告。因此,如果中介服務聯播網在逾時後完成初始化,仍可在該工作階段中處理日後的廣告請求。

您可以藉由呼叫 MobileAds.getInitializationStatus(),繼續在整個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尚未準備就緒的原因?

AdapterStatus.getDescription() 說明轉接器為何不能用來處理廣告請求,

onUserEarnedReward() 回呼一律會在 onAdDismissedFullScreenContent() 回呼之前呼叫嗎?

如果是 Google 廣告,所有 onUserEarnedReward() 呼叫都會發生在 onAdDismissedFullScreenContent() 之前。透過中介服務放送的廣告,第三方廣告聯播網的導入作業會決定回呼順序。如果廣告聯播網 SDK 提供單一關閉回呼與獎勵資訊,中介服務轉接程式會在 onAdDismissedFullScreenContent() 之前叫用 onUserEarnedReward()
