In Eclipse go to:
"Project" -> "Properties" -> "Java Build Properties"
On the "Order and Export" tab I checked "Android Private Libraries" on my project. I also did this for the library project it references. This fixed my class not found errors following upgrading to SDK 22.
You should refer the google play services library project in your map project.
Import your library project to your worksace. import the same to eclipse.
Right click on your project. goto properties. Choose android. click android. browse and add the library project.
