Create and Obtain API Key for Google Maps Android API v2 service

Google Map V2 on Fragment Class

The first thing that we will handle is the import of Google Map classes.
To get the Google Maps files we need to download the last version of
Google Play Services via the Android SDK Manager.

After you downloaded the Google Play Services

Import google play service library and also copy the lib to your  workspace 

you can found play service library here " \extras\google\google_play_services\libproject\google-play-services_lib "

Add the library to your project

import the support library this can be done very easily
using Eclipse: Right-Click you project and choose “Android Tools” and then choose
“Add Support Library…”:

1.  import android.os.Bundle; 
2.  import android.support.v4.app.Fragment;
