Question about add ads in Cocoonjs

Hello, i was using intel xdk for crosswalk but now i change to cocoonjs because you can add advertisements like banner easy. Yesterday they accepted me for premium and now i only need to put the ads. I search for tutorials because im going to use mopub and leadbolt. But when i register in mopub and leadbolt they ask for the apk url in google play, but my app isn´t uploaded yet. The question is: I need to uploaded first my app,and then add the ads with a update?

Thanks for the help.

You do not need to have the app uploaded first, even if you do not link your apk url, the ads will still compile into your game if set up correctly.

I found this tutorial really helpful:
