Gmaps in a fragment Api 2 Android app

I'm developing an app with a fragment that contains a map (from google not Openstreet). But I'm at really beginning and I have a problem in the xml of the fragment. Eclipse return me this error:

"Fatal error: main Caused by: android.view.InflateException:Binary XML file line #4: Error inflating class com.google.android.gms.maps.MapView"

Below I paste the fragment_geolocalizzazione.xml :

    <?xml version="1.0" encoding="utf-8"?>


    <com.google.android.gms.maps.MapView
    xmlns:android="http://ift.tt/nIICcg"
    xmlns:map="http://ift.tt/GEGVYd"
    android:id="@+id/mapView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:clickable="true"
    android:background="#00000000" >

    </com.google.android.gms.maps.MapView>

I inflate this layout but it returns error on this ("com.google.android.gms.maps.MapView") and it return null when the main activity call it.
