Implement banner ads in Android
Implement banner ads in your Android app. Create banner view objects, display them in your layout, and use a listener to manage ad events.

Banner ads require a specific type of dedicated banner placement.
You can place the banner view object into your view hierarchy, just like you would any other view. This allows you to customize the position of each banner instance, or display multiple banners.
Note
app-ads.txt is an IAB initiative to combat fraud and create transparency in the advertising ecosystem. Ensure that you set up the app-ads.txt file as described. Otherwise, banner demand might be significantly decreased.
Script implementation
The following script sample is an example implementation for displaying two banner ads on the screen, and buttons for testing them.
This example uses a single listener for multiple banner view objects. You can also have a different listener for each banner view object.
Implementing the MREC banner format
To display a medium rectangle (MREC) sized ad format in your app, ensure the proper dimensions are used, such as 300x250, 300x300, or 450x450. In the case of a 300x250 MREC banner ad specifically, replace this in the following example code:
new UnityBannerSize(320, 50)
With this adjusted dimension:
new UnityBannerSize(300, 250)
Banner ad example
Construct a to handle impression, click, and show failure events, then pass it into along with the placement ID and a , which supports fixed or adaptive dimensions for anchored and inline layouts. Optionally include mediation metadata and ad markup for bidding, then call with the built configuration and a . On a successful load, retrieve the banner's via to insert it into your layout.
BannerShowListenerBannerConfiguration.BuilderBannerSizeBannerAd.load()LoadListenerViewad.getView()BannerShowListener showListener = new BannerShowListener() { @Override public void onImpression(@NonNull BannerAd ad) { /* impression */ } @Override public void onClicked(@NonNull BannerAd ad) { /* clicked */ } @Override public void onFailedToShow(@NonNull BannerAd ad, @NonNull UnityAdsError error) { /* show failure */ } }; BannerConfiguration.Builder builder = new BannerConfiguration.Builder( placementId, new BannerSize( 320, 50 ), showListener ) .withMediationInfo( createMediationInfo() ); if ( AppLovinSdkUtils.isValidString( bidResponse ) ) { builder.withAdMarkup( bidResponse ); } BannerAd.load( builder.build(), new LoadListener<BannerAd>() { @Override public void onAdLoaded(@Nullable BannerAd ad, @Nullable UnityAdsError error) { if ( error == null ) { loadedBannerAd = ad; listener.onAdViewAdLoaded( ad.getView() ); // retrieve view via getView() } else { // failure } } } );
