I want to display Google ads in my app but it shows error unexpected namespace prefix xmlns at this tag xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads". If I remove this line then it shows Error parsing XML:unbound prefix. Please help me to identify that where things go wrong. Here is my code.
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="@drawable/background_port"
tools:context=".MainActivity">
<LinearLayout xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
>
<com.google.ads.AdView android:id="@+id/adView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
ads:adUnitId="a151b801b7c1d6b"
ads:adSize="BANNER"

Once a namespace prefix is created, it cannot be changed or deleted. The workaround is to move all your code to a new Developer Organization, where you can setup the desired Namespace Prefix.
One of the primary motivations for defining an XML namespace is to avoid naming conflicts when using and re-using multiple vocabularies. XML Schema is used to create a vocabulary for an XML instance, and uses namespaces heavily.
It means XML namespace. Basically, every element (or attribute) in XML belongs to a namespace, a way of "qualifying" the name of the element.
Annotation Type XmlNs @Retention(value=RUNTIME) @Target(value={}) public @interface XmlNs. Associates a namespace prefix with a XML namespace URI. Usage. @XmlNs annotation is intended for use from other program annotations. See "Package Specification" in javax.
