try out by replacing your map fragment in xml by this,

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
    <fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        class="com.google.android.gms.maps.SupportMapFragment" />

</LinearLayout>

Issue is in your xml file defining class name in fragment.

You problem is the way you added google-play-services to your project:

I have copied the google-play-services.jar in libs folder and set in the build path of eclipse.

This is wrong! Read the first 3 steps of this blog post I wrote to get an idea of how to do it correctly:

Google Maps API V2

In short, you should import google-play-services as a project in your workspace. and then reference it from your project.

Finally resolve my issue. Issue occurred because Eclipse was not able to find google-play-services_lib(even it was showing green mark while adding as a library). I tried same process on another machine and everything worked fine.

So I changed my entire Android SDK location and it woked fine.
