Admob HandleFailedToReceiveAd "No fill"

[Ziad Khalid]

Hello, I'm using Unity3D 4.3 and I used the sample provided in this plugin, it's called HelloWorld. I followed the instructions in the README file, Also I used an ad IP I got from Admob site. But even though I did everything needed ( I think ) the ads still doesn't show up. I built the game and put it in my device ( Samsung Galaxy S3 ) I tapped on "Request Banner" and then I waited a couple of seconds then I tapped on "Show Banner" and nothing is shown.

The logcat says "HandleFailedToReceiveAd event received with message: No fill" 

what does "No fill" mean and how to fix that? if that's the problem...

Logcat is attached.

No fill means there is no inventory from the ad server. One common mistake I've seen is trying to request a banner ad with an ad unit ID that was configured for interstitial ads in the AdMob front-end. Double check your ad unit, and make sure there is a setting for "Refresh rate". If there is a setting for "Interstitial Timeout" but no setting for refresh rate, you've got an interstitial ad unit.

Thanks,

Eric
