Answer 1

Change the namespace to

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

Ad.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <com.google.android.gms.ads.AdView
        android:id="@+id/adview"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        ads:adSize="BANNER" />

</LinearLayout>

NOTE :

Use this Namespace for new SDK

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

Answer 2

Try add "ads:adSize" to XML like below:

<com.google.android.gms.ads.AdView
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    android:id="@+id/adview"
    ads:adSize="SMART_BANNER"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
     />

Answer 3

Remove "adView.setAdSize(AdSize.SMART_BANNER);" from your java file.

Refer below:

Here is the XML layout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          xmlns:ads="http://schemas.android.com/apk/res-auto"
          android:orientation="vertical"
          android:layout_width="match_parent"
          android:layout_height="match_parent">
<TextView android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:text="@string/hello"/>
<com.google.android.gms.ads.AdView android:id="@+id/adView"
                       android:layout_width="match_parent"
                       android:layout_height="wrap_content"
                       ads:adSize="BANNER"
                       ads:adUnitId="INSERT_YOUR_AD_UNIT_ID_HERE"/>
</LinearLayout>

And here is your java file

package com.google.example.gms.ads.xml;

import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;

import android.app.Activity;
import android.os.Bundle;

/**
 * A simple {@link Activity} which embeds an AdView in its layout XML.
 */
public class BannerXMLSample extends Activity {

  private static final String TEST_DEVICE_ID = "INSERT_YOUR_TEST_DEVICE_ID_HERE";

  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    // The "loadAdOnCreate" and "testDevices" XML attributes no longer available.
    AdView adView = (AdView) this.findViewById(R.id.adView);
    AdRequest adRequest = new AdRequest.Builder()
        .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
        .addTestDevice(TEST_DEVICE_ID)
        .build();
    adView.loadAd(adRequest);
  }
}
