Namespace prefix "xmlns" found for tag fragment

I am trying to use maps in my xml, the code is below

<RelativeLayout xmlns:android="http://ift.tt/nIICcg"
xmlns:tools="http://ift.tt/LrGmb4"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >

<Spinner 
    android:id="@+id/spr_place_type"
    android:layout_width="wrap_content"
    android:layout_height="60dp"
    android:layout_alignParentTop="true" />

<Button
    android:id="@+id/btn_find"
    android:layout_width="wrap_content"
    android:layout_height="60dp"        
    android:layout_alignParentTop="true"
    android:layout_toRightOf="@id/spr_place_type"
    android:text="@string/str_btn_find" />    

<fragment xmlns:android="http://ift.tt/nIICcg"
    android:id="@+id/map"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@id/spr_place_type"
    class="com.google.android.gms.maps.SupportMapFragment" />
