I include this plugin on the setttings based on the documentation:
plugins = { ["CoronaProvider.ads.admob"] = { -- required publisherId = "com.coronalabs", }, },
and then in my application I have
ads.init( "admob", "ca-app-pub-8145556512349498/5075330363", adListener ) ads.show( "banner", { x=0, y=0 } )
where ca-app-pub-8145556512349498/5075330363 is the Ad unit ID from Admob site, but I suppose is not correct, because this field should be the appId, how can I found this?
