獎勵廣告

激励广告 让您可以向与视频广告、试玩广告和调查问卷互动的用户奖励应用内商品。

前提条件

  • Google 移动广告 SDK 19.7.0 或更高版本。
  • 通读入门指南

务必用测试广告进行测试

构建和测试应用时,请确保使用测试广告,而不是实际投放的广告。否则,可能会导致您的帐号被暂停。

对于 Android 激励广告,加载测试广告最简便的方法就是使用下面的专用测试广告单元 ID:

ca-app-pub-3940256099942544/5224354917

该测试广告单元 ID 已经过专门配置,可为每个请求返回测试广告,您可以在自己应用的编码、测试和调试过程中随意使用该测试广告单元 ID。只是一定要在发布应用前用您自己的广告单元 ID 替换该测试广告单元 ID。

載入獎勵廣告物件

系統會透過呼叫 RewardedAd 類別上的靜態 load() 方法,並傳入 RewardedAdLoadCallback 來載入獎勵廣告。這項作業通常在 ActivityonCreate() 方法中完成。請注意,如同其他格式載入回呼,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 相關的事件。顯示 RewardedAd 之前,請務必依下列方式設定回呼:

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.")
}

[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傳送額外資料,則應使用獎勵廣告的自訂資料功能。在獎勵廣告物件上設定的任何字串值,都會傳遞至 SSV 回呼的 custom_data 查詢參數。如未設定自訂資料值,SSV 回呼中就不會顯示 custom_data 查詢參數值。

下列程式碼範例示範如何在請求廣告前,設定獎勵廣告物件的自訂資料。

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,就必須在顯示廣告前完成指定。

常见问题解答

初始化调用是否有超时?
10 秒后,即使中介广告联盟仍未完成初始化,Google 移动广告 SDK 也会调用 OnInitializationCompleteListener
在获得初始化回调时,如果某些中介广告联盟尚未准备就绪,该怎么办?

我们建议您在 OnInitializationCompleteListener 的回调中加载广告。即使中介广告联盟尚未就绪,Google 移动广告 SDK 仍会向该广告联盟请求广告。因此,如果中介广告联盟在超时后完成初始化,它仍然可以在该会话中为将来的广告请求提供服务。

您可以通过调用 MobileAds.getInitializationStatus() 继续在整个应用会话中轮询所有适配器的初始化状态。

如何找出特定中介广告联盟未就绪的原因?

AdapterStatus.getDescription() 描述了适配器未准备好为广告请求提供服务的原因。

系统是否始终会在调用 onAdDismissedFullScreenContent() 回调之前调用 onUserEarnedReward() 回调?

对于 Google Ads,所有 onUserEarnedReward() 调用都发生在 onAdDismissedFullScreenContent() 之前。对于通过中介投放的广告,由第三方广告联盟 SDK 的实现情况决定回调顺序。对于为单次关闭回调提供奖励信息的广告联盟 SDK,中介适配器会在调用 onAdDismissedFullScreenContent() 之前调用 onUserEarnedReward()
