Handle callbacks from background thread

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 add a banner view to view hierarchy after an ad loads:

Kotlin

 BannerAd 
 . 
 load 
 ( 
  
 adRequest 
 , 
  
 object 
  
 : 
  
 AdLoadCallback<BannerAd 
 > 
  
 { 
  
 override 
  
 fun 
  
 onAdLoaded 
 ( 
 ad 
 : 
  
 BannerAd 
 ) 
  
 { 
  
  // Add the banner view to the view hierarchy on the UI thread. 
  
 activity 
 ?. 
 runOnUiThread 
  
 { 
  
 binding 
 . 
 bannerViewContainer 
 . 
 addView 
 ( 
 ad 
 . 
 getView 
 ( 
 requireActivity 
 ())) 
  
 } 
  
 } 
  
 }, 
 )

Java

 BannerAd 
 . 
 load 
 ( 
  
 adRequest 
 , 
  
 new 
  
 AdLoadCallback<BannerAd 
 > 
 () 
  
 { 
  
 @Override 
  
 public 
  
 void 
  
 onAdLoaded 
 ( 
 @NonNull 
  
 BannerAd 
  
 ad 
 ) 
  
 { 
  
  // Add the banner view to the view hierarchy on the UI thread. 
  
 runOnUiThread 
 ( 
  
 () 
  
 -> 
  
 binding 
 . 
 bannerViewContainer 
 . 
 addView 
 ( 
 ad 
 . 
 getView 
 ( 
 MainActivity 
 . 
 this 
 ))); 
  
 } 
  
 });
