激励广告

使用集合让一切井井有条 根据您的偏好保存内容并对其进行分类。

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

在构建和测试应用时,请确保使用的是测试广告,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:

/6499/example/rewarded

该测试广告单元 ID 已经过专门配置,可确保每个请求返回的都是测试广告。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。需要注意的一点是,请务必在发布应用前用您的广告单元 ID 替换该测试广告单元 ID。

加载激励广告对象

针对 RewardedAd 类调用静态 load() 方法并传入 RewardedAdLoadCallback 可加载激励广告。这通常是在 ActivityonCreate() 方法中完成的。请注意,与其他广告格式加载回调一样,RewardedAdLoadCallback 会利用 LoadAdError 提供较高保真度的错误详情。

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) {
    AdManagerAdRequest adRequest = new AdManagerAdRequest.Builder().build();
    RewardedAd.load(this, "/6499/example/rewarded",
      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 = AdManagerAdRequest.Builder().build()
    RewardedAd.load(this,"/6499/example/rewarded", 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
       }
    })
  }
}

[可选] 验证服务器端验证 (SSV) 回调

对于需要服务器端验证回调中额外数据的应用,应使用激励广告的自定义数据功能。在激励广告对象上设置的任何字符串值都将传递给 SSV 回调的 custom_data 查询参数。如果未设置自定义数据值,custom_data 查询参数值不会出现在 SSV 回调中。

以下代码示例演示了如何在请求广告之前对激励广告对象设置自定义数据。

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
  }
})

如果您要设置自定义奖励字符串,则必须在展示广告之前设置。

设置 FullScreenContentCallback

FullScreenContentCallback 处理与展示 RewardedAd 相关的事件。在展示 RewardedAd 之前,请务必按如下方式设置回调:

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.")
  }
}

展示广告

展示激励广告时,您将使用 OnUserEarnedRewardListener 对象处理奖励事件。

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.")
}
