Solution 1:

I had this problem. My problem was solved when I added the google play services with following steps:

1. Import google Play Services as project. Don't forget to check 'Copy Project to your workspace' option
2. Right click on your app project and click Properties. Select Android. Click 'Add library'. Select google play services from list.
3. You should make sure that you remove Jar if you have included previously.
4. Clean your project and build again.
