Java Error in an XML file: aborting build

I downloaded an android app so I could learn how to build map apps, and I need some help getting this running well. I have added the necessary libraries, and configured AVD. Now I need to get it to run but I keep running into the error below and need some help figuring this one out. Doing project cleans has not helped solve this one.

Where do I look for the problem in this case? I delete the main.xml.out file, run it, it is recreated and then the same error. What do I do to get to the main problem? And what could it be?

 ---this is the content of my main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >
    <FrameLayout 
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
        <com.google.android.maps.MapView
        android:id="@+id/mapView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:clickable="true"
        android:apiKey="0yNvLwdK_rMeMIYkMdOTNTttBcxQ0O_rgNLE_Mw"/>
    </FrameLayout>
</LinearLayout>

This is the error log

Is there a way to configure this so the xml.out files generated are deleted on error/exit?
