Android Google Maps fragment in the xml. I get "Unexpected namespace prefix"

I'm trying to learn android, and having followed the instructions on how to use the Google Maps API V.2 I now got it working.
However, the instructions on how to configure the initial state of the maps, found at developers.google.com, suggests a namespace defined in the xml-file, in this case "map".

The xml-code below gives med the error "Unexpected namespace prefix "map"". Trying to define the xmlns:map inside the fragment tag gave the same error but with "xmlns".

I'm obviously missing some fundamental xml-knowledge here, can someone help me out?

<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:map="http://schemas.android.com/apk/res-auto" <!-- Definition -->
android:layout_width="match_parent"
android:layout_height="match_parent">

<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment"
map:cameraBearing="112.5"/> <!-- PROBLEM -->

</RelativeLayout>

Answer

you have to do two things:

first: https://docs.google.com/document/pub?id=19nQzvKP-CVLd7_VrpwnHfl-AE9fjbJySowONZZtNHzw

Add the dependency to Google Play Services into your project

Project -> Properties -> Android -> Library, Add -> google-play-services_lib

second: https://developers.google.com/maps/documentation/android/intro

Select Project > Properties, select Java Build Path, and navigate to Libraries. Select Add External Jars, include the following jar files, and click OK:

<android-sdk-folder>/extras/android/compatibility/v4/android-support-v4.jar

now my project shows no errors anymore :) regards, marcel
