Introducing adaptive anchor banners

In today’s mobile-first world, app publishers who use banner ads must serve them across a greater variety of screen sizes and layouts than ever before. Existing responsive banner ad formats often produce ads that are too small and not optimally tailored to the specifications of each device.

To address this, we’ve created a new banner type called adaptive anchor banners. These banners dynamically adjust creative size to deliver an ad that is ideally sized across all of your user’s devices, without the need to write any custom code.

These banners are designed to replace standard 320x50 and leaderboard banner sizes, as well as smart banners. Here is a comparison of the 3 formats on a standard mobile device:

Migrating your banner implementation to adaptive

Here are a few simple steps to update your banner implementation to use adaptive banners:

  1. Ensure your UI supports a variable height banner. Depending on what constraints or layout mechanism you are using to position your banner, you may need to remove height constraints such that the layout accepts variable content size.
    • For Android this can be done using WRAP_CONTENT.
    • For iOS constrain your banner in terms of X and Y positions, you may also give it a width constraint, but ensure any height constraint or content size is placeholder only.

    Note that the max height is 15% of the device height or 90px, whichever is smaller.

  2. Use the adaptive banner ad size APIs to get an adaptive ad size. The adaptive ad size APIs are available for different orientations.

    AdSize.getCurrentOrientationAnchoredAdaptiveBannerAdSize(context, width)
    AdSize.getPortraitAnchoredAdaptiveBannerAdSize(context, width)
    AdSize.getLandscapeAnchoredAdaptiveBannerAdSize(context, width)



    Which one you use depends on your use case. If you want to preload ads for a given orientation, use the API for that orientation. If you only need a banner for the current orientation of the device, use the current orientation API.

    Once you have an ad size, set that on your banner view as usual before loading an ad. The banner will resize to the adaptive ad size as long as you have laid it out without any conflicting constraints.

  3. Update your mediation adapters. If you use mediation, update your mediation adapters to the latest version. All open source mediation adapters that support banners have been updated to support the adaptive banner ad size requests. Note that adapters will still only return ad sizes supported by their corresponding ad network SDK, and those ads will be centered in your adaptive banner view.

Share your feedback about AdMob and Ad Manager mobile app integration

We’re continuously improving our guides, code samples, and other developer resources for the Google Mobile Ads SDK to help you integrate AdMob and Ad Manager into your mobile apps.

To learn more about what's working well and what could be improved, we're announcing our second annual developer feedback survey for the Google Mobile Ads SDK. We'd like to hear from you about where we should focus our efforts.


Your answers will be completely anonymous. The survey should take about 15 minutes to complete and will close on September 30, 2019.

Your feedback is truly important to us. Here are a few highlights of the changes we made based on feedback from last year’s survey:

  1. Continuous translations of the developer docs in several languages
  2. Continuous build integration of sample applications via Travis CI
  3. Launched a Developer tutorials playlist on the Google AdMob YouTube channel
  4. Launched the App Policy Center to help publishers handle policy violations

Please let us know what you’d like us to focus on next. Thank you in advance for helping us continue to improve the developer experience for everyone.

Google Mobile Ads SDK for Android: How to migrate to v18.0.0

Earlier this week, Google Play services released a major update to many of its libraries to migrate all Android support library dependencies to Jetpack (using androidx.* packages). This includes the play-services-ads library from the Google Mobile Ads SDK, which has been updated to 18.0.0.

While the Google Mobile Ads SDK itself hasn’t changed between version 17.2.1 and 18.0.0, you’ll need to migrate your own app and all of your dependencies to AndroidX in order to pick up play-services-ads 18.0.0 or any future versions. This is particularly important if you use AdMob mediation, as several mediation partners have dependencies on Android support libraries that aren’t compatible with AndroidX.

To make the migration process as smooth as possible for you, Android Studio offers an easy way to convert your project and its dependencies to AndroidX using the Migrate to AndroidX option.

Migrate to AndroidX

Android Studio 3.2 or higher includes a Refactor > Migrate to AndroidX menu option to convert your project to use AndroidX. We’ll demonstrate what happens when converting our BannerExample to AndroidX.

  1. Change the project’s compileSdkVersion to 28. This is a prerequisite for migrating to AndroidX.
  2. Right click the app module, and select Refactor > Migrate to AndroidX. You’ll be given an option to save your project as a zip file before Android Studio converts it.
  3. Select Do Refactor to complete the migration.

What changed?

Here is the project before the migration:

And here is the project afterwards:

First, you’ll notice that the package name for AppCompatActivity has changed to androidx.appcompat.app. The refactor has changed this project’s com.android.support:appcompat-v7:26.1.0 dependency to androidx.appcompat:appcompat:1.0.0 and fixed the associated imports.

Second, this migration added a gradle.properties file with these two lines:


These properties ensure your project and its dependencies use AndroidX, by rewriting any binaries that are using an Android support library. See Using AndroidX for more details on these flags.

Now that your project is converted to AndroidX, you can safely update your play-services-ads dependency to 18.0.0 in your project-level build.gradle file:

dependencies {
implementation 'androidx.appcompat:appcompat:1.0.0'
implementation 'com.google.android.gms:play-services-ads:18.0.0'

As always, you can follow the release notes to learn what’s changed in the Google Mobile Ads SDK. We’d also love to hear about how your migration went! If you have any questions about the release or have trouble migrating, please reach out to us on the Google Mobile Ads SDK developer forum.

Announcing v17.0.0 of the Android Google Mobile Ads SDK

Google Mobile Ads SDK v17.0.0 for Android has just been released, and it comes with two important changes that you should be aware of:

  1. A tag is now required in AndroidManifest.xml.
  2. NativeAppInstallAd and NativeContentAd APIs are deprecated in favor of UnifiedNativeAd.

Required AndroidManifest.xml changes

Starting in version 17.0.0, if you are an AdMob publisher you are now required to add your AdMob app ID in your AndroidManifest.xml file. Once you find your AdMob app ID in the AdMob UI, add it to your manifest adding the following tag:

<!-- TODO: Replace with your real AdMob app ID -->

Failure to add this tag will result in the app crashing at app launch with a message starting with "The Google Mobile Ads SDK was initialized incorrectly."

What if I'm using Google Ad Manager instead of AdMob?

Publishers using Google Ad Manager will need to declare themselves as an Ad Manager app with a different tag to avoid the same crash:


See the getting started guide (AdMob | Ad Manager) for additional details on how to make this change.

NativeAppInstallAd and NativeContentAd APIs are deprecated

This release also officially deprecates the NativeAppInstallAd and NativeContentAd APIs in favor of the previously released UnifiedNativeAd API. The UnifiedNativeAd APIs offer a consolidated way to render any type of native ad, reducing the number of lines of code needed to integrate native ads by up to 50%.

The following example shows how to load both app install and content ads using the new unified API:

AdLoader adLoader = new AdLoader.Builder(context, "ca-app-pub-3940256099942544/2247696110")
.forUnifiedNativeAd(new UnifiedNativeAd.OnUnifiedNativeAdLoadedListener() {
public void onUnifiedNativeAdLoaded(UnifiedNativeAd unifiedNativeAd) {
// Show the ad.
adLoader.loadAd(new AdRequest.Builder().build());

Check out the native ads guide to get started with the unified API.

What else changed?

See the release notes for a full list of changes. If you have any questions about the release, please reach out to us on the Google Mobile Ads SDK developer forum.
