add google maps in an android application

Question

I'm new in Android development. I want to add Google maps to my application. I have done lots of searches but still the same problem arises when I run the application "Unfortunately , application has stopped"

So this is my java class

package com.example.hellomap;
import com.google.android.maps.MapView;
import android.support.v4.app.FragmentActivity;
import android.os.Bundle;


public class MainActivity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map_main);
        MapView map =(MapView) findViewById(R.id.map);

    }

}

the xml file :

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

and the Manifest

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.hellomap"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="16" />

        android:glEsVersion="0x00020000"
        android:required="true"/>
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <uses-library android:name="com.google.android.maps"/>
        <activity
            android:name="com.example.hellomap.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <meta-data
    android:name="com.google.android.maps.v2.API_KEY"
    android:value="AIzaSyCKSp9pb7g8Wkga2SgeoT_MSe0JG59DkSU" />
    </application>

</manifest>

The LogCat shows:

EXCEPTION :- ClassNotFoundException please check GooglePlayService Library Project First.

Second Thing You Can Not Type Cast Fragment To Map View, please read this

Update:-

Follow The Step:-

1)Create New Project

2)Import GooglePlayService Library project into Your Workspace.

3)assign Google play Service library project as library project to your project

4)now add Map Fragment/Supported Map Fragment into your activity layout file

5)make sure this class found

how to check==>press control Key from keyboard and click on class name id you found class then it's okay other wise fix it first. i prefer to use Supported Fragment.

6)define all permission as describe in link i posted previously.

6)now its time to generate api key for map ,follow the step from given link.

Thanks i hope its help
