Banner & MREC Ads

Banner and MREC ads are rectangular ad formats that occupy a portion of an app’s layout—often positioned at the top or bottom of the screen or placed inline within scrollable content. They remain visible as users interact with the app, allowing for uninterrupted gameplay or usage, and can be refreshed automatically after a set period.

The following sections show you how to load and then show and hide a banner or MREC ad.

Loading a Banner or MREC

The following code shows you how to load a banner or MREC by using your Ad Unit ID, desired position, and (for banners) desired background color. MAX will size the ad for you automatically:

Banners

const BANNER_AD_UNIT_IDS = {
  "android" : "«Android-banner-ad-unit-ID»",
  "ios" : "«iOS-banner-ad-unit-ID»"
}

func initializeBannerAds:
  var platform = OS.get_name().to_lower() # "android", "ios", etc.
  var ad_unit_id = adUnitsDict.get(platform)

  # MAX automatically sizes banners to 320×50 on phones and 728×90 on tablets
  AppLovinMAX.create_banner(ad_unit_id, AppLovinMAX.BannerPosition.BOTTOM_CENTER)

MRECs

const MREC_AD_UNIT_IDS = {
  "android" : "«Android-MREC-ad-unit-ID»",
  "ios" : "«iOS-MREC-ad-unit-ID»"
}

func initializeMRecAds:
  var platform = OS.get_name().to_lower() # "android", "ios", etc.
  var ad_unit_id = adUnitsDict.get(platform)

  # MRECs are sized to 300x250 on phones and tablets
  AppLovinMAX.create_mrec(ad_unit_id, AppLovinMAX.AdViewPosition.BOTTOM_CENTER)

Displaying a Banner or MREC

To show a banner or MREC, make the following call:

Banners

AppLovinMAX.show_banner(«ad-unit-ID»);

MRECs

AppLovinMAX.show_mrec(«ad-unit-ID»);

To hide a banner or MREC, make the following call:

Banners

AppLovinMAX.hide_banner(«ad-unit-ID»);

MRECs

AppLovinMAX.hide_mrec(«ad-unit-ID»);

Adaptive Banners

注意

Only Google bidding and Google AdMob, Google Ad Manager, and Liftoff Monetize support adaptive banners. MAX sizes banners from other networks normally.

Google recommends that developers include a 50px padding between the banner placement and the app content. This makes it less likely that users will accidentally click on the banner. Refer to Google’s “About Confirmed Click” policy for more information and best practices.

Adaptive banners are responsive banners with heights that derive from the device type and the width of the banner. To disable adaptive banners, set the adaptive_banner flag, as in this example:

AppLovinMAX.set_banner_extra_parameter(«ad-unit-ID», "adaptive_banner", "false")

Call AppLovinMAX.get_adaptive_banner_height_for_width(«width») to get the banner height, and then adjust your content accordingly.

Stopping and Starting Auto-Refresh

You may want to stop auto-refresh for an ad. This may be the case when you hide an ad or you want to manually refresh. Stop auto-refresh with the following call:

AppLovinMAX.stop_banner_auto_refresh(«ad-unit-ID»);

Start auto-refresh for an ad with the following call:

AppLovinMAX.start_banner_auto_refresh(«ad-unit-ID»);
