“First, use AdMob to get your unit ID for your package name. Add this to the Android project settings and add a “Show Ad Banner” blueprint node. This should be all you need.”
I have done exactly this and have published my app about 3 or 4 different times to Google Play for alpha and beta testing, yet my testers still do not see any ads.
Is it necessary to add the line “addTestDevice(“deviceserialnumber”)” in order for the testers to even see ads? I understand it’s unethical/unlawful to publish actual ads in a testing version, but does AdMob not even send ad data to a Beta version for this reason?
