# Revenue reporting

## Implementation

Since version **1.7.0**, apps can receive an estimated revenue that has likely been generated by an ad.

To do this, it is just needed to implement the corresponding listener for each ad format, as shown in the example below:

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

```kotlin
val bannerAd: BannerAd

bannerAd.listener = object : BannerAd.Listener() {
    override fun onBannerRevenuePaid(ad: BannerAd, data: Revenuedata) {
        // Invoked when the ad has generated revenue
    }
}
```

{% endtab %}

{% tab title="Java" %}

```java
BannerAd mBannerAd;

mBannerAd.setListener(new BannerAd.Listener() {
    @Override
    public void onBannerRevenuePaid(@NonNull BannerAd ad,
                                    @NonNull Revenuedata data) {
        // Invoked when the ad has generated revenue
    }
});
```

{% endtab %}
{% endtabs %}

The listener receives an object of type `RevenueData` that contains the following fields:

<table><thead><tr><th width="139.62109375">Field</th><th width="140.36328125">Type</th><th>Description</th></tr></thead><tbody><tr><td><code>revenue</code></td><td><code>AdValue</code></td><td>The revenue generated by the ad</td></tr><tr><td><code>source</code></td><td><code>String</code></td><td>The revenue source</td></tr></tbody></table>

In addition, the `AdValue` class contains the following fields that represent the revenue:

<table><thead><tr><th width="140.49609375">Field</th><th width="190.46484375">Type</th><th>Description</th></tr></thead><tbody><tr><td><code>currency</code></td><td><code>String</code></td><td>The currency corresponding to the revenue</td></tr><tr><td><code>precision</code></td><td><code>AdValue.Precision</code></td><td>The accuracy of the information. It can be <code>ESTIMATED</code>, <code>PRECISE</code> or <code>PUBLISHER_DEFINED</code></td></tr><tr><td><code>value</code></td><td><code>Double</code></td><td>The revenue value</td></tr></tbody></table>

## Integration with Firebase

Below, a basic example is shown of how to report the revenue information to Firebase:

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

```kotlin
override func onBannerRevenuePaid(ad: BannerAd, data: RevenueData) {
    val bundle = Bundle().apply {
        putString("currency",   data.revenue.currency)
        putString("precision",  data.revenue.precision?.name)
        putString("source",     data.source)
        putDouble("value",      data.revenue.value)
    }

    Firebase.analytics.logEvent("ad_revenue", bundle)
}
```

{% endtab %}

{% tab title="Java" %}

```java
@Override
public void onBannerRevenuePaid(@NonNull BannerAd ad,
                                @NonNull RevenueData data) {
    Bundle bundle = new Bundle();

    bundle.putString("source", data.getSource());
    
    AdValue revenue = data.getRevenue();

    bundle.putString("currency",  revenue.getCurrency());
    bundle.putDouble("value",     revenue.getValue());
    
    AdValue.Precision precision = revenue.getPrecision();
    
    if (precision != null) {
        bundle.putString("precision", precision.name());
    }

    FirebaseAnalytics.getInstance(context).logEvent("ad_revenue", bundle);
}
```

{% endtab %}
{% endtabs %}
