I just imported an example of the google map api V2 for android to test. It's missing the google-play-services_lib.jar. I can't find this library. Where do I get it?

First check that your sdk contains Google Play Services installed or not.
For that you do the below steps
In Eclipse--->Window--->Android SDK MAnager--->Check Google Play Services installed in extras.
Then you add the google plays services jar by find that one at the below location
your-android-sdk\extras\google\google_play_services\libproject\google-play-services_lib\libs

@RakeshGondaliya Close your eclipse and start SDK Manger manually and try to install it. It may work.

Thanks for sharing your knowledge... It was a stupid mistake.. Actually the message Access denied was in German , so I didn't understood... Now it worked with Admin login.. Once again thanks...
