To show AdMob banner ads in an InAppBrowser using Cordova/Ionic, you'll need to follow these steps:

  1. Install AdMob Plugin: Install the Cordova AdMob plugin in your Ionic project. You can use the cordova-plugin-admob-free plugin, which is a popular choice for AdMob integration in Cordova/Ionic apps.

    Run the following command to install the plugin:

    cordova plugin add cordova-plugin-admob-free
  2. Configure AdMob: Configure AdMob by setting up your AdMob account and obtaining the AdMob app ID and the Ad unit ID for the banner ad. You can get these IDs from the AdMob dashboard.

  3. Initialize AdMob: In your Ionic app's JavaScript code (usually in your app's app.js or app.component.ts), initialize the AdMob plugin with your AdMob app ID.

    // Initialize AdMob with your AdMob app ID admob.banner.config({ id: 'YOUR_ADMOB_APP_ID', isTesting: false, // Set to true during development to receive test ads });
  4. Show the InAppBrowser and Banner Ad: When you want to show the InAppBrowser with the AdMob banner ad, use the following code:

    // Show the AdMob banner ad admob.banner.prepare().then(() => { // The AdMob banner is ready // Show the InAppBrowser const targetUrl = ''; const options = 'location=yes,toolbar=yes,hardwareback=no,closebuttoncaption=Close'; const inAppBrowserRef =, '_blank', options); }).catch((error) => { console.error('Error preparing AdMob banner:', error); });

    Note that the options variable in the method allows you to customize the appearance and behavior of the InAppBrowser. Adjust these options according to your requirements.

  5. Handle InAppBrowser Events (Optional): You can handle events from the InAppBrowser, such as when the browser is closed or when a new page starts to load. For example, you can listen for the exit event to know when the InAppBrowser is closed and then hide the AdMob banner ad.

    inAppBrowserRef.addEventListener('exit', () => { // The InAppBrowser is closed // Hide the AdMob banner ad admob.banner.hide(); });
  6. Test the AdMob Banner (Optional): During development, set the isTesting option to true when initializing AdMob. This will ensure that test ads are shown instead of real ads while testing your app.

    admob.banner.config({ id: 'YOUR_ADMOB_APP_ID', isTesting: true, // Set to true during development to receive test ads });

That's it! With these steps, you should be able to show AdMob banner ads in your InAppBrowser within your Cordova/Ionic app. Remember to handle the InAppBrowser events appropriately to manage the visibility of the banner ad based on the user's interaction with the browser.
