Google Maps API V2 fragment failing to inflate

Google Maps API V2 fragment failing to inflate

This is my first time developing an Android application and my first
objective is to make a simple map control appear on the screen. Code and
everything looks ok except for the fact that the application crashes when
running on my 2.3.7 phone! I am using the exemple from Google API v2 page
and still it is not working.
My Android phone is running a 2.3.7 Android version.
The code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MapActivity" >
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
EDIT: I'm new to this site and using the tags "pre" and "code" made the
other android tags hidden.
What is happening?
