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.
Carica un oggetto dell'annuncio con premio
Gli annunci con premio vengono caricati chiamando il metodo load()
statico nella
classe RewardedAd
e trasmettendo un RewardedAdLoadCallback
. In genere
questa operazione viene eseguita nel metodo onCreate()
di un Activity
.
Come accade per i callback di caricamento di altri formati, RewardedAdLoadCallback
sfrutta LoadAdError
per fornire dettagli sull'errore a precisione più elevata.
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
}
})
}
}
Impostazione di FullScreenContentCallback
L'elemento FullScreenContentCallback
gestisce gli eventi relativi alla visualizzazione del tuo RewardedAd
. Prima di mostrare RewardedAd
, assicurati di impostare il callback in questo modo:
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.")
}
}
Mostra l'annuncio
Quando mostri un annuncio con premio, utilizzerai un oggetto OnUserEarnedRewardListener
per gestire gli eventi premio.
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.")
}
[Facoltativo] Convalidare i callback di verifica lato server (SSV)
Le app che richiedono dati aggiuntivi nei callback della verifica lato server dovrebbero utilizzare la funzionalità dei dati personalizzati degli annunci con premio. Qualsiasi valore di stringa impostato su un oggetto annuncio con premio viene trasmesso al parametro di query custom_data
del callback SSV. Se
non è impostato alcun valore dei dati personalizzati, il valore del parametro di query custom_data
non sarà
presente nel callback della SSV.
Il seguente esempio di codice mostra come impostare dati personalizzati su un oggetto annuncio con premio prima di richiedere un annuncio.
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
}
})
Se vuoi impostare la stringa premio personalizzata, devi farlo prima di mostrare l'annuncio.
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()
.
