Rewarded ads

Prerequisites

• Google Mobile Ads SDK 19.7.0 or higher.
• Follow the Get Started guide to import the Google Mobile Ads SDK and update your Android manifest.

Always test with test ads

When building and testing your apps, make sure you use test ads rather than live, production ads. Failure to do so can lead to suspension of your account.

The easiest way to load test ads is to use our dedicated test ad unit ID for Android rewarded ads:

/6499/example/rewarded

It's been specially configured to return test ads for every request, and you're free to use it in your own apps while coding, testing, and debugging. Just make sure you replace it with your own ad unit ID before publishing your app.

For more information about how the Mobile Ads SDK's test ads work, see Test Ads.

Load a rewarded ad object

Rewarded ads are loaded by calling the static load() method on the RewardedAd class and passing in a RewardedAdLoadCallback. This is usually done in the onCreate() method of an Activity. Notice that like other format load callbacks, RewardedAdLoadCallback leverages LoadAdError to provide higher fidelity error details.

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

public class MainActivity extends Activity {
  private RewardedAd mRewardedAd;
  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());
          mRewardedAd = null;
        }

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

class MainActivity : AppCompatActivity() {

  private var mRewardedAd: 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())
        mRewardedAd = null
      }

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

Set the FullScreenContentCallback

The FullScreenContentCallback handles events related to displaying your RewardedAd. Before you show your RewardedAd, make sure to set the callback like so:

mRewardedAd.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.");
    mRewardedAd = null;
  }

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

mRewardedAd?.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.")
    mRewardedAd = null
  }

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

Show the ad

When you show a rewarded ad, you will use an OnUserEarnedRewardListener object to handle reward events.

if (mRewardedAd != null) {
  Activity activityContext = MainActivity.this;
  mRewardedAd.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.");
}

if (mRewardedAd != null) {
  mRewardedAd?.show(this, OnUserEarnedRewardListener() {
    fun onUserEarnedReward(rewardItem: RewardItem) {
      var rewardAmount = rewardItem.amount
      var rewardType = rewardItem.type
      Log.d(TAG, "User earned the reward.")
    }
  })
} else {
  Log.d(TAG, "The rewarded ad wasn't ready yet.")
}
