App’s finally built without problems, but admob ads not showing.
I’ve done the integration steps successfully with valid licence key, what can I do?
On https://developers.google.com/admob/android/quick-start it’s mentioned some lines to be added to androidmanifest.xml file and gradle.build, I tried adding them and build failed, I removed them and build is successful but ads are not showing, are these lines mandatory when monetizing my app?
