AdMob App Open Ads : Android Studio Implementation
What are AdMob App Open Ads?
AdMob App Open Ads are a unique ad format designed to display full-screen advertisements during app loading times or app transitions, such as when launching the app or switching between app screens.
Unlike traditional interstitial ads that interrupt the user’s flow within the app, App Open Ads are displayed in a non-intrusive manner, enhancing the user experience and maintaining engagement.
Key Benefits
Non-Intrusive User Experience
By displaying ads during natural app transitions, App Open Ads avoid interrupting the user’s flow, resulting in a seamless and non-disruptive experience. Users can continue using the app without feeling frustrated or annoyed by sudden ad interruptions.
Higher Revenue Potential
App Open Ads provide an excellent opportunity for developers and publishers to boost their revenue. By monetizing app loading times and transitions, which would otherwise remain unutilized, developers can significantly increase their ad inventory and maximize revenue potential.
AdMob App Open Ads Implementation Guide [AdMob Setup]
Step 1: Open AdMob and create an unit for App Open Ad.
Please select the app in which you want to display the ads. Select Ad units from the menu.
Click on “Add ad unit” button.
Next, you can choose ‘App open’ from the list of options.
Let’s give our ad unit a name. It’s better to keep the name short.(Here MyAppOpenAd) Finally click on ‘Create ad unit’.
You can then view the App ID and App Open Ad Unit ID. Copy these IDs for future use. In this tutorial, We use test unit id for implementing app open ads. (Test ID: ca-app-pub-3940256099942544/3419835294)
App Open Ads Implementation [Android Studio Setup]
Create a new Android Project or use existing one.
Add the following dependencies to [build.gradle (:app)]
def lifecycle_version = "2.2.0"
implementation "androidx.lifecycle:lifecycle-extensions:$lifecycle_version"
implementation "androidx.lifecycle:lifecycle-runtime:$lifecycle_version"
annotationProcessor "androidx.lifecycle:lifecycle-compiler:$lifecycle_version"Sync your project.
Let’s place the App ID within the <application></application> tags of the AndroidManifest.xml file.
<meta-data
android:name="com.google.android.gms.ads.APPLICATION_ID"
android:value="ca-app-pub-XXX"/>Replace ‘ca-app-pub-XXX’ with your own App ID.
In Android Studio, let’s create a new class called MyApplication.java

Let’s modify the AndroidManifest.xml file as below. Add MyApplication as android:name.
<application
android:name=".MyApplication"
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name">
<!-- .... -->
</application>Run your app. The ad will show when you switch back to your app screen.
