问题
My head almost exploded today because the entire day I tried to solve the problem with my AdView from AdMob. I'm getting an error mentioned in the title. I googled through 3 pages but nothing. Same error whatever I do. This is my XML file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFF"
android:orientation="vertical" >
<ImageView
android:id="@+id/imageView1"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.48"
android:src="@drawable/butters10" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="42dp" >
<Button
android:id="@+id/prev"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:background="@drawable/prev" />
<Button
android:id="@+id/next"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:background="@drawable/next" />
</RelativeLayout>
<com.google.ads.AdView
xmlns:ads="http://schemas.android.com/apk/libs/com.google.ads"
android:id="@+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
ads:loadAdOnCreate="true"
app:adSize="BANNER"
app:adUnitId="------------------------------" >
</com.google.ads.AdView>
</LinearLayout>
I tried to change the app keyword to ads but the problem still shows up.
Another thing is I actually want to add the same ad this the same unit-id to more than one activity. I added this exactly code to my first activity xml file, and everything works fine, but in the second activity it doesn't work at all. Thank you for any help.

Change
xmlns:ads="http://schemas.android.com/apk/libs/com.google.ads"
to
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
All the documentation seems to refer to the namespace as being at /lib/ not /libs/
And reference the tags using ads
<com.google.ads.AdView
xmlns:ads="http://schemas.android.com/apk/libs/com.google.ads"
android:id="@+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
ads:loadAdOnCreate="true"
ads:adSize="BANNER"
ads:adUnitId="------------------------------" />

To make it work with Google Play services use:
xmlns:ads="http://schemas.android.com/apk/res-auto"
in your XML file.

My requirement was to be able to dynamically pass in ad unit IDs instead of specifying them in xml. Turns out the framework does not like a mix of these, so I am creating my ads 100% programmatically:
public class AdMobBanner extends FrameLayout {
private AdView adView;
public AdMobBanner(Context context, AdParams params) {
super(context);
adView = new AdView(context);
FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
layoutParams.gravity = Gravity.CENTER;
adView.setLayoutParams(layoutParams);
adView.setAdSize(AdSize.BANNER);
adView.setAdUnitId(params.getAdUnitId());
addView(adView);
}
public void showAdvert(AdParams params) {
AdRequest.Builder builder = new AdRequest.Builder();
for (String id: params.getTestDevices()) {
builder.addTestDevice(id);
}
adView.loadAd(builder.build());
}
@Override
public void pause() {
adView.pause();
}
@Override
public void resume() {
adView.resume();
}
}
The AdParams class is my own class and you can replace it with your own class, or pass in strings, but the general solution is posted here.

The "loadAdOnCreate" and "testDevices" XML attributes no longer available. To make your ad working with Google Play Services
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);
}
}

Add android:theme="@android:style/Theme.Translucent" to your Android Manifest after meta-data
