Know if correct "Ad unit ID" was used by my develoepr

I have an iOS app and soon making an Android version. Is there anyway to know if my developer have used the Ad unit ID that I have provided him? Is it possible for him to do a rotation between my Ad unit ID and his own?

I expect the revenue to be more based on numbers of users, therefore I have this doubt.

I tried to monitor my phone using fiddler but it looks like AdMob requests are encrypted. I want to make sure the app is only showing Ad units that are under my account.

The Adsense Management API doesn't provide this info as Accounts.adunits.list only retrieves ad units tied to your account. Perhaps you can contact admob support to find out about the ad unit ids requesting for ads in your package name.

OR You can also decompile the live apk:

1. If you have access to the google play developer account where the app is published, navigate to Release Management -> App Releases -> MANAGE PRODUCTION

2. Download the current apk in production:

3. Go to http://www.javadecompilers.com/apk decompile and download the java files. If you don't want to decompile your apk online, you can use any good offline decompiler available in the play store

4. Do a search for "setAdUnitID" in the downloaded project's root directory. You should see your ad unit ids:

This works even if your project is obfuscated with proguard, however note ad units can be rotated remotely so if a variable is used for the ad unit id, you may want to go through the code to be sure the ad unit isn't fetched from a server.

Also note that your apk can be published on third-party app stores, meaning you'd have to go through these steps for every apk in a different store.

Ideally admob should have info about adunits tied to a specific app so you may want to contact their support for assistance
