AdMob Interstitial Ads don't show up on Android device
I'm trying to test the interstitial ads on my android game before publishing but they don't show up and I can't understand why. I successfully set up the iOS version compiling an RC build so I did the same for the android version but to no avail.
Here's how I set up the AdMob services section:
I put the App ID in the AdMob App ID textbox and the Unit ID in the other two.
I hope someone can help me.
