问题描述

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="------------------------------" />
