回答1:

This error usually returned for a couple of reasons.

• There were no ads that are available to serve the specific user.
• Content width is not enough for the ad to be shown fully
• You just created the ad element at AdMob and it'll take some time before it'll start serving you ads.
• You are using the wrong App ID or ID. Just double check them as you might have just copied the example from documentation and forgot to change it to your unit's app id or id.
• Last but not least, you didn't properly initialize the AdMob. Go back and read the documentation again.
