                         ads:adUnitId="XXX"
                         ads:refreshInterval="60"/>


</LinearLayout>

Please help me out. I am stuck here :(

回答1:

Probably a namespace issue. You have to define the namespace.

try adding

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

回答2:

New Admob SDK (Google Play services) requiried another namespace

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

回答3:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
    android:layout_width="fill_parent" android:id="@+id/rltvLayoutPromote"
    android:layout_height="fill_parent">
    <LinearLayout android:id="@+id/linearLayoutwebview"
        android:layout_height="wrap_content" android:layout_width="wrap_content"
        android:orientation="vertical">
        <WebView android:id="@+id/webViewPromote"
            android:layout_width="fill_parent" android:layout_height="fill_parent"
            android:fitsSystemWindows="true" />
    </LinearLayout>
    <LinearLayout android:layout_width="fill_parent"
        android:id="@+id/ad_layout" android:layout_height="wrap_content"
        android:gravity="bottom" android:layout_alignParentBottom="true"
        android:layout_alignBottom="@+id/home_layout">
        <com.google.ads.AdView android:layout_width="wrap_content"
            android:layout_height="wrap_content" ads:adUnitId="XXXXXXXXXX"
            ads:adSize="BANNER" android:id="@+id/adView" ads:refreshInterval="60" />
        <!--            put 3 if not working-->
    </LinearLayout>
</RelativeLayout>

and put this lines in manifest.xml file

  <uses-permission android:name="android.permission.INTERNET"/>
  <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
  <meta-data android:value="true" android:name="ADMOB_ALLOW_LOCATION_FOR_ADS" />

the above code is working perfectly for me... visit this site for complete reference help forandroid-admob
