Your xml is using a MapFragment, not a SupportMapFragment.

Change your xml to use a SupportMapFragment and it should work:

<fragment class="com.google.android.gms.maps.SupportMapFragment"
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

Also, make sure that you're inflating the correct layout in the call to setContentView().
