My Java Code

NativeExpressAdView adView = (NativeExpressAdView)findViewById(R.id.adView);

    AdRequest request = new AdRequest.Builder()
        .addTestDevice("YOUR_DEVICE_ID")
        .build();
    adView.loadAd(request);

My XML for same is below

<com.google.android.gms.ads.NativeExpressAdView
     xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
    android:id="@+id/adView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    ads:adUnitId="ca-app-pub-3940256099942544/6300978111"
     ads:adSize="320x80">
</com.google.android.gms.ads.NativeExpressAdView>

Thanks

Answer 1

It seems that the namespace prefix declaration for ads is wrong

Try replacing

xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"

with

 xmlns:ads="http://schemas.android.com/apk/res-auto"
