Events

You can observe the lifecycle of a FuseAdView by listening to its emitted events.

Currently, the following events are available:

An ad has started loading
An ad has finished loading successfully
An error occurred while loading an ad
An ad impression was recorded

Android

To listen for events on Android, implement the FuseAdViewListener interface and add it to your FuseAdView instance:

class EventListener : FuseAdViewListener {
  override fun onEvent(adView: FuseAdView, event: FuseAdViewEvent) {
    val eventName = when (event) {
      is FuseAdViewEvent.Loading -> "Loading"
      is FuseAdViewEvent.Loaded -> "Loaded"
      is FuseAdViewEvent.Impression -> "Impression recorded"
      is FuseAdViewEvent.Error -> "Error(${event.error.message})"
    }
    println(eventName)
  }
}

val adView = FuseAdView(context, code = "<zone_code>")
adView.addListener(EventListener())

Jetpack Compose

In Jetpack Compose, pass an event handler lambda to ComposeFuseAdView:

fun onEvent(adView: FuseAdView, event: FuseAdViewEvent) {
  val eventName = when (event) {
    is FuseAdViewEvent.Loading -> "Loading"
    is FuseAdViewEvent.Loaded -> "Loaded"
    is FuseAdViewEvent.Impression -> "Impression recorded"
    is FuseAdViewEvent.Error -> "Error(${event.error.message})"
  }
  println(eventName)
}

ComposeFuseAdView(
  code = "<zone_code>",
  onEvent = ::onEvent,
)

iOS

On iOS, set the delegate property of FuseAdView to an object that implements the FuseAdViewDelegate protocol:

class EventDelegate: NSObject, FuseAdViewDelegate {
  func onEvent(adView: FuseAdView, event: FuseAdViewEvent) {
    let eventName: String
    switch event {
      case .loading: eventName = "Loading"
      case .loaded: eventName = "Loaded"
      case .impression: eventName = "Impression"
      case .error(let error): eventName = "Error(\(error))"
      @unknown default: eventName = "Unknown event"
    }
    print(eventName)
  }
}

let adView = FuseAdView(code: "<zone_code>")
adView.delegate = EventDelegate()

SwiftUI

In SwiftUI, provide an event handler when creating a FuseAdViewRepresentable instance:

func onEvent(adView: FuseAdView, event: FuseAdViewEvent) {
  let eventName: String
  switch event {
    case .loading: eventName = "Loading"
    case .loaded: eventName = "Loaded"
    case .impression: eventName = "Impression"
    case .error(let error): eventName = "Error(\(error))"
    @unknown default: eventName = "Unknown event"
  }
  print(eventName)
}

FuseAdViewRepresentable(
  code: "<zone_code>",
  onEvent: onEvent
)
