I know this error: java.lang.NoClassDefFoundError: com.google.android.gms.R$styleable

You should import google play services lib project into workspace, not just add external jar to project. Here is detailed info:

Android developers topic related "Copy the /extras/google/google_play_services/libproject/google-play-services_lib library project into the source tree where you maintain your Android app projects. If you are using Eclipse, import the library project into your workspace. Click File > Import, select Android > Existing Android Code into Workspace, and browse to the copy of the library project to import it."
