Error Handling

An ad request can fail for a number of reasons including network errors, or an invalid parameter.  When an ad request failed to load the ad, the AdListener.onAdError event is called, returning an AdError object that contains an error code and message.

A complete list of error codes with descriptions can be found below: 

Code Error Name Description

200 NETWORK_ERROR The ad request failed due to a problem with network connectivity.
