AdMob not working when testing on device

Hi, 

I am trying to add AdMob to my game as a banner at the bottom of the screen. I added the code and then tested it on a device. However the Ads do not show when I test it on my Android phone. 

This is what I have included in the code for AdMob. Is there something I am missing ? also, Is it just necessary to add the code ? How do I set it up so that the revenue will be linked to my account in AdMob ? Is this done automatically or manually ? 

Thank in advance for any help. 

main.lua 

local provider = "admob"   local appID = "com.daleoshea.example"   local ads = require "ads"     ads.init( provider, appID ) ads.show("banner", {x=0, y=display.contentHeight})

build.settings

 plugins =     {         ["CoronaProvider.ads.admob"] =         {             publisherId = "com.coronalabs"         },     }, 

That AppID is an Apple iAds style AppID.  AdMob uses a really big number string like: ca-app-pub-53871639238388424/239548374838

There will be separate versions of those strings for Android Banners, Android Interestitials, Apple banners and Apple Interstitials.  AdMob calls this an Ad Unit Id.
