This page covers the instructions to handle callbacks from a background thread.
GMA Next-Gen SDK runs ad load and event callbacks on a background thread. When performing UI-related operations within these callbacks, ensure you explicitly dispatch them to the UI thread.
The following examples show a toast after an ad loads:
Kotlin
adView
.
loadAd
(
adRequest
,
object
:
AdLoadCallback<BannerAd>
{
override
fun
onAdLoaded
(
ad
:
BannerAd
)
{
// Show a toast on the UI thread.
runOnUiThread
{
Toast
.
makeText
(
activity
,
"Ad loaded."
,
Toast
.
LENGTH_SHORT
).
show
()
}
}
},
)
Java
adView
.
loadAd
(
adRequest
,
new
AdLoadCallback<BannerAd>
()
{
@Override
public
void
onAdLoaded
(
@NonNull
BannerAd
ad
)
{
// Show a toast on the UI thread.
runOnUiThread
(()
-
>
Toast
.
makeText
(
activity
,
"Ad loaded."
,
Toast
.
LENGTH_SHORT
).
show
()
);
}
});
