Answer 1

After V20, admob drop the use of UnifiedNativeAdView to use the new NativeAdView instead

• you have to change the declaration "final UnifiedNativeAdView unifiedNativeAdView " to "final NativeAdView adView"
• and dont forget to : import com.google.android.gms.ads.nativead.NativeAdView;

like this:

        final NativeAdView adView = activity.findViewById(R.id.native_ad_view);
