Adaptive banners are the next generation of responsive ads, maximizing
performance by optimizing ad size for each device. Improving on fixed-size
banners, which only supported fixed heights, adaptive banners let developers
specify the ad-width and use this to determine the optimal ad size.
To pick the best ad size, inline adaptive banners use maximum instead of fixed
heights. This results in opportunities for improved performance.
When to use inline adaptive banners
Inline adaptive banners are larger, taller banners compared to anchored adaptive
banners. They are of variable height, and can be as tall as the device screen.
They are intended to be placed in scrolling content, for example:
When implementing adaptive banners in your app, note these points:
Ensure you are using the latest version of the Google Mobile Ads SDK, and if
using mediation
, the latest versions of your mediation adapters.
The inline adaptive banner sizes are designed to work best when using the
full available width. In most cases, this will be the full width of the
screen of the device in use. Be sure to take into account applicable safe areas.
AdSize.getInlineAdaptiveBannerAdSize(int width, int maxHeight)
When using the inline adaptive banner APIs, the Google Mobile Ads SDK
returns an AdSize with the given width and an
inline flag. The height is either zero or maxHeight, depending on which
API you're using. The actual height of the ad is made available when it's
returned.
An inline adaptive banner is designed to be placed in scrollable content. The
banner can be as tall as the device screen or limited by a maximum height,
depending on the API.
Implementation
Follow the steps below to implement a simple inline adaptive banner.
Get an inline adaptive banner ad size. The size you get will be used to
request the adaptive banner. To get the adaptive ad size make sure that you:
Get the width of the device in use in density independent pixels, or set
your own width if you don't want to use the full width of the screen.
You can use MediaQuery.of(context) to get the screen width.
Use the appropriate static methods on the ad size class, such as
AdSize.getCurrentOrientationInlineAdaptiveBannerAdSize(int width)
to get an inline adaptive AdSize object for the current orientation.
If you wish to limit the height of the banner, you can use the static
method AdSize.getInlineAdaptiveBannerAdSize(int width, int maxHeight).
Create a BannerAd object with your ad unit ID, the adaptive ad size, and
an ad request object.
Load the ad.
In the onAdLoaded callback, use BannerAd.getPlatformAdSize() to get the
updated platform ad size and update the AdWidget container height.

width of the screen, accounting for insets:
