Im adding an custom adUnitId to my PublisherAdView banner AD, provided by publishes in order to trigger Google Mobile Ads SDK to call my custom made event handler class, but instead i get this error message:
Ads: Could not load custom event implementation class: MyCustomBannerAdapter, assuming old implementation.
Ads: Could not instantiate mediation adapter: com.google.ads.mediation.customevent.CustomEventAdapter.
java.lang.NullPointerException: Attempt to invoke interface method 'java.lang.Object java.util.Map.get(java.lang.Object)' on a null object reference

This is MyCustomBannerAdapter:
public final class MyCustomBannerAdapter extends Adapter implements CustomEventBanner, CustomEventInterstitial {
@Override
public void initialize(Context context, InitializationCompleteCallback
initializationCompleteCallback, List<MediationConfiguration> list) {
}
@Override
public VersionInfo getVersionInfo() {
return null;
}
@Override
public VersionInfo getSDKVersionInfo() {
return null;
}
@Override
public void requestBannerAd(Context context, CustomEventBannerListener customEventBannerListener,
String s, AdSize adSize, MediationAdRequest mediationAdRequest, Bundle bundle) {
}
@Override
public void onDestroy() {
}
@Override
public void onPause() {
}
@Override
public void onResume() {
}
@Override
public void requestInterstitialAd(Context context, CustomEventInterstitialListener
customEventInterstitialListener, String s, MediationAdRequest mediationAdRequest, Bundle bundle){
}
@Override
public void showInterstitial() {
}
}
And in my activity i have imported MyCustomBannerAdapter like this:
import com.example.event.adapter.MyCustomBannerAdapter
Build gradle:
implementation 'com.google.android.gms:play-services-ads:19.0.0'
AndroidManifest:
<meta-data
android:name="com.google.android.gms.ads.AD_MANAGER_APP"
android:value="true" />
I was following official Gooogle Mobile Ads SDK documentation:
https://developers.google.com/ad-manager/mobile-ads-sdk/android/quick-start
Any idea how to trigger calling MyCustomBannerAdapter?
