In cases where an ad fails to load, a
callback
is called which provides a LoadAdError
object.
For AdView
, the following is called:
Kotlin
fun
onAdFailedToLoad
(
error
:
LoadAdError
)
Java
public
void
onAdFailedToLoad
(
LoadAdError
adError
)
;
The following example shows the information available when an ad fails to load:
Kotlin
override
fun
onAdFailedToLoad
(
error
:
LoadAdError
)
{
// Gets the domain from which the error came.
val
errorDomain
=
error
.
domain
// Gets the error code. See
// https://developers.google.com/admob/android/reference/com/google/android/gms/ads/AdRequest#constant-summary
// for a list of possible codes.
val
errorCode
=
error
.
code
// Gets an error message.
// For example "Account not approved yet". See
// https://support.google.com/admob/answer/9905175 for explanations of
// common errors.
val
errorMessage
=
error
.

// Gets additional response information about the request. See
// https://developers.google.com/admob/android/response-info
// information.
val
responseInfo
=
error
.
responseInfo
// Gets the cause of the error, if available.
val

=
error
.

// All of this information is available using the error's toString() method.

}
Java
@Override
public
void

{

String
errorDomain
=

getDomain

In version 23.5.0 of Google Mobile Ads SDK, verbose logging was enhanced to include a stack trace of where the ad fails to load. These message don't indicate a crash, but rather identify the unique source of the error. The following table provides common error logs, descriptions, and suggested actions for resolution:
