 If you want to track your ad revenue with the Admob SDK, you can use our SDK-to-SDK integration to pass this information to the Adjust backend. To do this, you will need to construct an Adjust ad revenue object containing the information you wish to record, then pass the object to the `trackAdRevenue` method.
