1st thing I did was downloaded "google Play Services for Froyo" from my eclipse android sdk manager. Than I added "google-play-services.jar" in to "Referenced Libraries" in eclipse project.

#------------------------------------------------------
# 2nd thing I did was to add ad on my layout xml file
# res > layout > mainXmlFile       
#-------------------------------------------------------





    <com.google.ads.AdView
        xmlns:ads = "http://schemas.android.com/apk/lib/com.google.ads"
            android:id = "@+id/adView"
            android:layout_width = "fill_parent"
            android:layout_height = "wrap_content"
            ads:adUnitId = "ci-apa-pab-44_myKey"
            ads:adSize = "BANNER"
            ads:testDevices = "TEST_EMULATOR, "
            ads:loadAdOnCreate = "true" />











#------------------------------------------
# Lastly I add permission in manifest file 
#AndroidManifest
#-------------------------------------------




 .......        
            <activity android:name="com.google.android.gms.ads.AdActivity"
                 android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>
        </application>
        <uses-permission android:name="android.permission.INTERNET"/>
      <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    </manifest>
