插页式激励广告(Beta 版)

插页式激励广告是一种 一种利诱性质的广告格式,可让您为每次展示 自动应用。与激励广告不同,用户 用户才能选择观看插页式激励广告。

前提条件

* Google 移动广告 SDK 19.2.0 或更高版本。

实现

植入插页式激励广告的主要步骤如下所示:

  • 加载广告
  • 注册全屏事件回调
  • 处理奖励回调
  • 展示广告
  • [可选] 验证 SSV 回调

加载广告

广告的加载是通过在load() RewardedInterstitialAd 类。加载方法需要上下文,您的广告 一个单元 ID、一个 AdRequest 对象和一个 RewardedInterstitialAdLoadCallback,在广告加载成功时收到通知;或 失败。已加载的 RewardedInterstitialAd 对象会作为形参在 onRewardedInterstitialAdLoaded() 回调。

以下示例展示了如何在 RewardedInterstitialAd MainActivity

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);

    new Thread(
            () -> {
              // Initialize the Google Mobile Ads SDK on a background thread.
              MobileAds.initialize(this, initializationStatus -> {});
              // Load an ad on the main thread.
              runOnUiThread(
                  () -> {
                    loadAd();
                  });
            })
        .start();
  }

  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)

    val backgroundScope = CoroutineScope(Dispatchers.IO)
    backgroundScope.launch {
      // Initialize the Google Mobile Ads SDK on a background thread.
      MobileAds.initialize(this@MainActivity) {}
      // Load an ad on the main thread.
      runOnUiThread {
        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
      }
    })
  }
}

注册回调

要接收有关展示事件的通知,您必须传递 FullScreenContentCallback 对象传递给广告的 setter。通过 FullScreenContentCallback 对象处理广告展示时的回调 以及何时关闭以下代码 展示了如何在 FullScreenContentCallback RewardedInterstitialAdLoadCallback:

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
    }
  })
}

处理奖励

如需展示您的插页式激励广告,请在 MainActivity 中实现 OnUserEarnedRewardListener 接口,以便在用户获得奖励时收到通知。

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!
  }
}

展示广告

实现 OnUserEarnedRewardListener 接口后,您可以使用广告的 show() 方法展示广告,如下所示:

Java

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

Kotlin

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

[可选] 验证服务器端验证 (SSV) 回调

需要在服务器端获取额外数据的应用 验证回调应使用 自定义数据功能。在激励广告上设置的任何字符串值 对象会传递给 SSV 回调的 custom_data 查询参数。如果拒绝 自定义数据值后,custom_data 查询参数值不会 。

以下代码示例演示了如何为激励广告设置自定义数据 插页式广告对象。

Java

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;
    ServerSideVerificationOptions options = new ServerSideVerificationOptions
        .Builder()
        .setCustomData("SAMPLE_CUSTOM_DATA_STRING")
        .build();
    rewardedInterstitialAd.setServerSideVerificationOptions(options);
  }
  @Override
  public void onAdFailedToLoad(LoadAdError loadAdError) {
    Log.d(TAG, loadAdError.toString());
    rewardedInterstitialAd = null;
  }
});

Kotlin

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
    val options = ServerSideVerificationOptions.Builder()
        .setCustomData("SAMPLE_CUSTOM_DATA_STRING")
        .build()
    rewardedInterstitialAd.setServerSideVerificationOptions(options)
  }

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

如果您要设置自定义奖励字符串,则必须在显示 。
