问题
I am working on a project in which I want to show a Map, for that I want to add google-play-service-lib but when I add it my R.java files gets deleted and not getting regenerated.
I tried adding google-play-service-lib into build path. After adding everything goes ok. But, when I run the project it gives an error says, java.lang.NoClassDefFoundError: com.google.android.gms.R$styleable
And when I add it into the project, R.java gets deleted. I tried number of permutations and combinations which I found on google and SO. But there is no feasible solution, which solves my problem.
Please help me out for this..!!

making sure your Google play services is present in same working directory and make this project as a reference to the original project..
Ensure you have the latest version (v2) of the Google Play Services installed.
Select Window > Android SDK Manager or run android at the command line.
Scroll to the bottom of the package list and select Extras > Google Play services. The Google Play services SDK is downloaded to your computer and installed in your Android SDK environment at <android-sdk-folder>/extras/google/google_play_services/
Add the Google Play Services project into your Eclipse workspace.
Click File -> Import..., select Android -> Existing Android Code into Workspace
Browse to and select <android-sdk-folder>/extras/google/google_play_services/libproject/google-play-services_lib
To add the dependency to Google Play Services into your project
Project -> Properties -> Android -> Library, Add -> google-play-services_lib
Providing the link you can see the importing Google play services
and even check your google play services is up to date by going to sdk manger...
