Interstitial ad load example

Use

LoadConfiguration.Builder

to construct a load request with the placement ID and mediation metadata, optionally including ad markup for bidding. Pass the built configuration to

InterstitialAd.load()

along with a

LoadListener

. The

onAdLoaded

callback receives the loaded

InterstitialAd

instance on success, or a

UnityAdsError

on failure. Retain the ad instance, as it's required to show the ad later.

Ads expire a set time after they load if they aren't shown. Set

onAdExpired

on the loaded ad instance to detect this and clear your reference. Calling

show()

on an expired ad fails. Do this in the same block where you store the ad, then use the callback to discard the stale reference and trigger a new

load()

call so a valid ad is ready the next time you need one.


InterstitialAd.load(loadConfig, (interstitialAd, error) -> {    if (interstitialAd != null) {        // Ad loaded successfully, ready to be shown        this.interstitialAd = interstitialAd;        interstitialAd.setOnAdExpired(expiredAd -> {            this.interstitialAd = null;            // reload here        });    } else {        // Handle load error    }});


InterstitialAd.load(loadConfig, { interstitialAd, error ->    if (interstitialAd != null) {        // Ad loaded successfully, ready to be shown        this.interstitialAd = interstitialAd        interstitialAd.onAdExpired = AdExpiredListener { _ ->            this.interstitialAd = null            // reload here        }    } else {        // Handle load error    }})

Interstitial ad show example

Call

show()

on the retained

InterstitialAd

instance, passing the activity, a

ShowConfiguration

, and an

InterstitialShowListener

. The listener provides callbacks for each stage of the ad's lifecycle:

onStarted

when the ad displays,

onClicked

when the user interacts with it,

onCompleted

when it closes, and

onFailed

if an error occurs — with the error details available via the

UnityAdsError

argument.


  loadedInterstitialAd.show(activity, new ShowConfiguration.Builder().build(), new InterstitialShowListener()  {     @Override     public void onStarted(@NonNull InterstitialAd ad)        { /* displayed */ }     @Override     public void onClicked(@NonNull InterstitialAd ad)        { /* clicked */ }     @Override     public void onCompleted(@NonNull InterstitialAd ad, @NonNull ShowFinishState state)      { /* hidden */ }     @Override     public void onFailed(@NonNull InterstitialAd ad, @NonNull UnityAdsError error)           { /* failed */ }  } );


loadedInterstitialAd.show(activity, ShowConfiguration.Builder().build(), object : InterstitialShowListener {  override fun onStarted(ad: InterstitialAd)                                 { /* displayed */ }  override fun onClicked(ad: InterstitialAd)                                 { /* clicked */ }  override fun onCompleted(ad: InterstitialAd, state: ShowFinishState)       { /* hidden */ }  override fun onFailed(ad: InterstitialAd, error: UnityAdsError)            { /* failed */ }})
