AdMob “Not enough space to show ad” error

Question

I'm new to Android. I added AdMob in my android app by making the following changes in main.xml:

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <LinearLayout
        xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" >
        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" />

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent" />

        <com.google.ads.AdView
            xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
            android:id="@+id/adView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            ads:adSize="BANNER"
            ads:adUnitId="XXXXXXXXX"
            ads:loadAdOnCreate="true" />
    </LinearLayout>
</TabHost>

My project is successfully running with no error, but I'm not getting the ad.

WARN/Ads(3805): Not enough space to show ad! Wants: <320, 50>, Has: <320, 0>.

It means there is no space for to display ad in your layout. Change it to RelativeLayout and align parent bottom.

<RelativeLayout
            xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            >
        <TabWidget
                android:id="@android:id/tabs"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content" />
        <FrameLayout
                android:id="@android:id/tabcontent"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:layout_below="@android:id/tabs"/>

    <com.google.ads.AdView
            xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
            android:id="@+id/adView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_alignParentBottom="true"
            ads:adSize="BANNER"
            ads:adUnitId="XXXXXXXXX"
            ads:loadAdOnCreate="true" 
            />
</RelativeLayout>

This is causing the issue.

 <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent" />

Your FrameLayout is occupying all the height on the view.So even if you write AdView below FrameLayout,It is getting 0 height.

Concider including AdMob at runtime inside your FrameLayout.
