This guide explains how to integrate interstitial ads into an Androidapp.
Prerequisites
- Google Mobile Ads SDK 19.7.0 or higher.
- Follow the Get Started guide toimport the Google Mobile Ads SDK and update your Android manifest.
Always test with test ads
When building and testing your apps, make sure you use test ads rather thanlive, production ads. Failure to do so can lead to suspension of your account.
The easiest way to load test ads is to use our dedicated test ad unit ID forAndroid interstitials:
ca-app-pub-3940256099942544/1033173712
It's been specially configured to return test ads for every request, and you'refree to use it in your own apps while coding, testing, and debugging. Just makesure you replace it with your own ad unit ID before publishing your app.
For more information about how the Mobile Ads SDK's test ads work, seeTest Ads.
Load an ad
Note: Make all calls to the Mobile Ads SDK on the main thread.To load an interstitial ad, call the InterstitialAd
staticload()
method and pass in anInterstitialAdLoadCallback
to receive the loadedad or any possible errors. Notice that like other format load callbacks,InterstitialAdLoadCallback
leveragesLoadAdError
to provide higher fidelity error details.
Set the FullScreenContentCallback
The FullScreenContentCallback
handles events related to displaying yourInterstitialAd
. Before showing InterstitialAd
, make sure to set thecallback:
Java
Kotlin
Show the ad
Interstitial ads should be displayed during natural pauses in the flow of an app.Between levels of a game is a good example, or after the user completes a task.To show an interstitial, use theshow()
method.
Some best practices
- Consider whether interstitial ads are the right type of ad for your app.
- Interstitial ads work best in apps with natural transition points.The conclusion of a task within an app, like sharing an image or completing agame level, creates such a point. Because the user is expecting a break in theaction, it's easy to present an interstitial ad without disrupting theirexperience. Make sure you consider at which points in your app's workflow you'lldisplay interstitial ads and how the user is likely to respond.
- Remember to pause the action when displaying an interstitial ad.
- There are a number of different types of interstitial ads: text, image,video, and more. It's important to make sure that when your app displays aninterstitial ad, it also suspends its use of some resources to allow the ad totake advantage of them. For example, when you make the call to display aninterstitial ad, be sure to pause any audio output being produced by your app.
- Allow for adequate loading time.
- Just as it's important to make sure you display interstitial ads at anappropriate time, it's also important to make sure the user doesn't have towait for them to load. Loading the ad in advance by calling
load()
before you intend to callshow()
can ensure that your app has a fully loaded interstitial ad at theready when the time comes to display one. - Don't flood the user with ads.
- While increasing the frequency of interstitial ads in your app might seemlike a great way to increase revenue, it can also degrade the user experienceand lower clickthrough rates. Make sure that users aren't so frequentlyinterrupted that they're no longer able to enjoy the use of your app.
