Question

将 com.google.android.gms:play-services-ads:19.4.0 更新到 20.1.0 仍然没有删除一些不推荐使用的方法。参考https://developers.google.com/android/reference/com/google/android/gms/ads/mediation/customevent/CustomEventListener#onAdFailedToLoad(com.google.android.gms.ads.AdError)

error: <anonymous my_app_adapter_file> is not abstract and does not override abstract method onAdFailedToLoad(int) in CustomEventListener


customEventListener = new CustomEventBannerListener() {
 //Deprecated still the CustomEventBannerListener expecting the int in onAdFailedToLoad
  @Override
  public void onAdFailedToLoad(int i) {
            
  }

 //latest
 @Override
 public void onAdFailedToLoad(AdError adError) {
 return;
 }
