I would like to add AppBrain’s AppLift ad network to my existing android app through AdMob mediation.
Do I need to create a new mediation ID for this new version or can I keep using the same mediation id?
What happens to old app versions (that don’t have AppLift) if I allocate traffic to AppLift?
I found a great explanation for AdWhirl, does AdMob mediation differ?
The Admob mediation layer handles this for you.
I assume that you have found the instructions on integrating AppLift into Admob mediation. When you add the new Custom Event with classname
com.appbrain.mediation.AdmobAdapter, Admob will offer this to your app. For older versions of the app, Admob will gracefully detect that this class is not present and choose the next option that you specify on the Admob console.
