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

    <LinearLayout android:id="@+id/linearLayout1"
        android:layout_height="wrap_content" android:layout_width="wrap_content"
        android:orientation="vertical">
        <WebView android:id="@+id/webView" 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">
 </LinearLayout>
            </RelativeLayout>

Answer 1

Edit the code as below, add these code

    android:layout_above="@+id/ad_layout"
    android:layout_alignParentTop="true"

Your xml should be like this:

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

<LinearLayout android:id="@+id/linearLayout1"
    android:layout_height="wrap_content" android:layout_width="wrap_content"
    android:orientation="vertical" android:layout_above="@+id/ad_layout"
    android:layout_alignParentTop="true">
    <WebView android:id="@+id/webViewMakeMp3" 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">
    </LinearLayout>
   </RelativeLayout>

Answer 2

i've use this in xml file

<?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/rltvLayout1"
    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/webView1"
            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="here put ID"
            ads:adSize="BANNER" android:id="@+id/adView" ads:refreshInterval="60" />

    </LinearLayout>
</RelativeLayout>

one more point i found is that
There are some changes to the way Admob works in version 4.1.0
1) Remove attrs.xml (or if you need it for your own custom attributes, remove the parts related to AdViews).

2) Change the namespace in your layout from xmlns:ads="http://schemas.android.com/apk/res/com.your.packagename" to xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads" see more...
