# Interstitial Ads

Interstitial Ads are loaded automatically. You can observe ad loading events by specifying the delegate:

```kotlin
val interstitial: BIDInterstitial? = BIDInterstitial(activity)
interstitial?.setLoadDelegate(interstitialLoadDelegate)
```

The delegate should implement the following methods:

```kotlin
var interstitialLoadDelegate : BIDFullLoad? = object : BIDFullLoad {
    override fun load(info: BIDAdInfo) {
        log("Interstitial - didLoadAd - adtag: ${info.adTag}")
    }

    override fun failLoad(info: BIDAdInfo, error: String) {
        log("Interstitial - didFailToLoadAd - adtag: ${info.adTag} Error:$error")
   }
}
```

To show an interstitial ad, call `showInterstitial` instance method:

```kotlin
interstitial.showInterstitial(activity, showDelegate)
```

The delegate should implement the following methods:

```kotlin
var fullShow : BIDFullShow? = object : BIDFullShow {
    override fun display(info: BIDAdInfo) {
        print("Interstitial - didDisplayAd. AdInfo: $adInfo")
    }

    override fun click(info: BIDAdInfo) {
        print("Interstitial - didClickAd. AdInfo: $adInfo")
    }

    override fun hide(info: BIDAdInfo) {
        print("Interstitial - didHideAd. AdInfo: $adInfo")
    }

    override fun failToDisplay(info: BIDAdInfo, error: String) {
        print("Interstitial - failToDisplay. All networks fail to display - error: $error")
    }

    override fun allNetworksFailedToDisplay() {
        print("Interstitial - allNetworksDidFailToDisplayAd." )
    }
}
```

## Stopping and Starting Auto-Load

By default, Interstitials preload ads before any load attempt. So an Interstitial can use already preloaded ads instead of waiting on a manual load call to load new ads. To disable this feature you need to call the following method:

```kotlin
interstitial.setAutoload(false)
```

Once you disable autoload, you should load ads manually every time you need them to show:

```kotlin
interstitial.load()
```

## Destroying of interstitial with resource release

```kotlin
interstitial.destroy()
```
