How do I place an advert within AlertDialog? [closed]

First you need to create a custom AlertDialog (en) . Soon after you enter the AdView referencing the dialog to findViewByID . See below:

AdView adView = (AdView)dialog.findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
adView.loadAd(adRequest);

See more detail regarding AdMob , read here at documentation .
