问题
I want to include an admob banner in my application and I got this weird error. Any help is deeply appreciated.
Here is the xml code
<com.google.ads.AdView android:id="@+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="bottom"
ads:adUnitId="..."
ads:adSize="BANNER"
/>
In the activity, I wrote the following code
adview = (AdView)findViewById(R.id.adView);
adview.setVisibility(View.VISIBLE);
AdRequest re = new AdRequest();
adview.loadAd(re);
In the Logcat I get the following error
Not enough space to show ad! Wants: <480, 75>, Has: <0, 800>
I suspected that there must have been an additional problem since I gave the width of the AdView as "wrap_content"
In the graphical view of the xml file there is this warning
and when I click on this error I see that there is an java.lang.UnsupportedOperationException
If you want to investigate further here is the full exception stack trace

Adview request starts after the layout been created. So you have to provide specific height and width to the layout of give some weight to the layout. You are provided wrap_content to the hieght and width of the layout, So it takes initially as a 0dp of width and all the view elements loads in the page based on the that. just try with fixed layout size like this,
<com.google.ads.AdView android:id="@+id/adView"
android:layout_width="480dp"
android:layout_height="75dp"
android:gravity="bottom"
ads:adUnitId="..."
ads:adSize="BANNER"
/>
And also you have to mention admob in the xmlns in the layout xml
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
In resources you have to declare the admob package like this
<?xml version="1.0" encoding="utf-8"?>
<resources>
<declare-styleable name="com.admob.android.ads.AdView">
</declare-styleable>
</resources>

I had the same problem and I solved it. You just make the right dimensions of admob, it requires 480, 75.
