1. Remove Existing Ad Integrations
Having multiple add integrations in your project — unless you are trying to do it on purpose — is likely to cause problems with building, compiling, and running your project.
If, however, you are working on a new project, you are in luck! Go ahead and skip to step 2.
Please make sure to commit all your work to version control before continuing. You almost certainly want to create a new branch before proceeding.
Clinton has created a new tool to ease this step; please try out The Ad Terminator. (Otherwise, follow Bruno’s document explaining how to remove ad integrations from an existing FPS (CCode) project.)
If you have an old version of the Google Play Services Resolver, I recommend deleting it. The AdMob package contains an updated version.
Your project is prepped. It will have errors in the console about Play Services resolver. Don’t worry about it right now.
