Test Ads

It is very important that while you are developing your application that you do not serve live ads. This is a requirement of the usage of AdMob and not following this correctly can have your application id blocked from using AdMob.

It is important to enable test ads during development so that you can click on them without charging Google advertisers. If you click on too many ads without being in test mode, you risk your account being flagged for invalid activity.

Sample ad units​

The quickest way to enable testing is to use Google-provided test ad units. These ad units are not associated with your AdMob account, so there's no risk of your account generating invalid traffic when using these ad units. Here are sample ad units that point to specific test creatives for each format:

Test Devices​

If you want to do more rigorous testing with production-looking ads, you can now configure your device as a test device and use your own ad unit IDs that you've created. Test devices can either be added in the AdMob UI or programmatically.

var config:RequestConfiguration = Adverts.service.getRequestConfiguration()
        .setTestDeviceIds( [ "33BE2250B43518CCDA7DE426D04EE231" ] )
;

Adverts.service.setRequestConfiguration( config );

This test id is listed in the device logs when testing an ad request.

Android​

Check the logcat output for a message that looks like this:

I/Ads: Use RequestConfiguration.Builder.setTestDeviceIds(Arrays.asList("33BE2250B43518CCDA7DE426D04EE231")) to get test ads on this device.

Android emulators are automatically configured as test devices.

Check the console (device logs) for a message that looks like this:

<Google> To get test ads on this device, set: GADMobileAds.sharedInstance.requestConfiguration.testDeviceIdentifiers = @[ @"2077ef9a63d2b398840261c8221a0c9b" ];
