# Interstitial Ad

## 1. 기본 요건

* [ADX Android SDK](/adx/android/integrate.md#2-adx-android-sdk)를 프로젝트에 추가합니다.
* Interstitial Ad용으로 발급받은 Ad Unit ID를 사용합니다.
* 광고를 요청하기 전에 [SDK 초기화](/adx/android/sdk-integration/initialize.md)를 먼저 진행합니다.
  * **SDK 초기화는 앱 실행 시 한 번만 호출**하여 주시고, **광고 요청은 초기화가 완료된 후**에 이뤄져야 합니다.

## 2. 구현

1. `InterstitialAd`를 인스턴스화하고 `InterstitialListener`를 추가합니다.
2. `loadAd()`를 호출하여 광고를 로드합니다.
3. 광고 로드가 완료되어 `onAdLoaded()` callback을 받은 후 `show()`를 하거나, `isLoaded()`로 표시할 광고가 있는지 확인 후, `show()` 로 광고를 표시합니다.
4. 노출 종료 시 `onDestroy()`에서 `InterstitialAd`의 `destroy()`를 호출하여 `InterstitialAd`를 제거합니다.

            }

            @Override

    }
    
    void show() {
        if (interstitialAd != null && interstitialAd.isLoaded()) {
            interstitialAd.show();
        }
    }
    
    @Override
    protected void onDestroy() {
        super.onDestroy();
    
        if (interstitialAd != null) {
            interstitialAd.destroy();
            interstitialAd = null;
        }
    }
}
```

{% endtab %}

{% tab title="Kotlin" %}

```kotlin
class InterstitialActivity : AppCompatActivity() {

    private var interstitialAd: InterstitialAd? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_fullscreen)

        interstitialAd = InterstitialAd(this, "<INTERSTITIAL_AD_UNIT_ID>"))

            override fun onAdError(errorCode: Int) {
            }

            override fun onAdClicked() {

        interstitialAd?.loadAd()
    }
    
    fun show() {
        if (interstitialAd?.isLoaded == true) {
            interstitialAd!!.show()
        }
    }

    override fun onDestroy() {
        super.onDestroy()

        interstitialAd?.destroy()
        interstitialAd = null
    }
}
```

{% endtab %}
{% endtabs %}

## 3. Callback

`InterstitialAd`의 `InterstitialListener`를 설정하여 특정 이벤트를 수신할 수 있습니다. 필요에 따라 구현해주세요.

{% tabs %}
{% tab title="Java" %}

```java
interstitialAd.setInterstitialListener(new InterstitialAd.InterstitialListener() {
    @Override
    public void onAdLoaded() {
    }

    @Override
    public void onAdError(int errorCode) {
    }

    @Override
    public void onAdClicked() {
    }

    @Override
    public void onAdImpression() {
    }

    @Override
    public void onAdClosed() {
    }

    @Override
    public void onAdFailedToShow() {
    }
});
```

{% endtab %}

{% tab title="Kotlin" %}

```kotlin
interstitialAd?.setInterstitialListener(object : InterstitialAd.InterstitialListener {
    override fun onAdLoaded() {
    }

    override fun onAdError(errorCode: Int) {
    }

    override fun onAdClicked() {
    }

    override fun onAdImpression() {
    }

    override fun onAdClosed() {
    }

    override fun onAdFailedToShow() {
    }
})
```

{% endtab %}
{% endtabs %}

## 4. Ad Revenue (OnPaidEvent)

* 광고 노출이 발생동안 예상되는 광고 수익을 받아볼 수 있습니다.
* 이는 미디에이션 설정 과정에서 수동적으로 설정한 값과 정확한 값이 섞여 있어서 예상 값으로 사용하시는 것을 권장드립니다.
* ecpm의 currency는 **USD**입니다.
* 아래와 같이 <mark style="color:red;">`OnPaidEvent`</mark> 콜백을 등록하여 사용하시면 됩니다.
* 광고 매출 데이터를 MMP와 연동할 수 있습니다. 자세한 사항은 아래 SDK 연동 가이드를 참조해 주십시오.
  * [애드저스트(Adjust)의 AD(X) SDK 연동 가이드](https://dev.adjust.com/ko/sdk/android/integrations/adx)
