android: Can I create multiple AdMob ADs for a single Android app?

I solve, we can create and use more than one mediation id for a single app. Create them at https://mediation.admob.com/#manage:mediation/create and just give them different names. You will either need to have 2 versions of your app, one for each each deployment site with its own mediation id, or a single version of your app that uses some form of configuration to choose the appropriate meidation id.
