Prerequisites
- Google Mobile Ads SDK 19.7.0 or higher.
- Complete the Get started guide.
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:
ca-app-pub-3940256099942544/5224354917
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.
リワード広告のオブジェクトを読み込む
リワード広告を読み込むには、RewardedAd
クラスの静的 load()
メソッドを呼び出して RewardedAdLoadCallback
を渡します。これは通常、Activity
の onCreate()
メソッドで行います。他の形式の読み込みコールバックと同様に、RewardedAdLoadCallback
は LoadAdError
を利用して、より再現性の高いエラーの詳細を提供します。
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
}
})
}
}
FullScreenContentCallback を設定する
FullScreenContentCallback
は、RewardedAd
の表示に関連するイベントを処理します。RewardedAd
を表示する前に、コールバックを以下のように設定してください。
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.")
}
}
広告を表示する
リワード広告を表示する際は、OnUserEarnedRewardListener
オブジェクトを使ってリワード イベントを処理します。
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.")
}
[省略可] サーバーサイド認証(SSV)コールバックを検証する
サーバーサイド認証コールバックで追加データを必要とするアプリでは、リワード広告のカスタムデータ機能を使用する必要があります。リワード広告オブジェクトに設定されている文字列値はすべて、SSV コールバックの custom_data
クエリ パラメータに渡されます。カスタムデータ値が設定されていない場合、SSV コールバックは custom_data
クエリ パラメータ値を持ちません。
次のコードサンプルは、広告をリクエストする前に、リワード広告オブジェクトにカスタムデータを設定する方法を示しています。
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
}
})
カスタム リワード文字列を設定する場合は、広告を表示する前に行う必要があります。
FAQ
- Is there a timeout for the initialization call?
- After 10 seconds, the Google Mobile Ads SDK invokes the
OnInitializationCompleteListener
even if a mediation network still hasn't completed initialization. - What if some mediation networks aren't ready when I get the initialization callback?
We recommend loading an ad inside the callback of the
OnInitializationCompleteListener
. Even if a mediation network is not ready, the Google Mobile Ads SDK still asks that network for an ad. So if a mediation network finishes initializing after the timeout, it can still service future ad requests in that session.You can continue to poll the initialization status of all adapters throughout your app session by calling
MobileAds.getInitializationStatus()
.- How do I find out why a particular mediation network isn't ready?
AdapterStatus.getDescription()
describes why an adapter is not ready to service ad requests.- Does the
onUserEarnedReward()
callback always get called before theonAdDismissedFullScreenContent()
callback? For Google ads, all
onUserEarnedReward()
calls occur beforeonAdDismissedFullScreenContent()
. For ads served through mediation, the third-party ad network SDK's implementation determines the callback order. For ad network SDKs that provide a single close callback with reward information, the mediation adapter invokesonUserEarnedReward()
beforeonAdDismissedFullScreenContent()
.
