Always get google play service update message by checking google play service in launcher app

I have an app that has google cloud messaging functionality so I am using the latest google service and since the development tool is android studio so I get the code for gcm from android developer site http://developer.android.com /google/gcm/client.html and then I was checking available google play services or not when starting the app

 public boolean checkPlayServices(Activity activity) {
    int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(context);
    if (resultCode != ConnectionResult.SUCCESS) {
        if (GooglePlayServicesUtil.isUserRecoverableError(resultCode)) {
            GooglePlayServicesUtil.getErrorDialog(resultCode, activity,
                    PLAY_SERVICES_RESOLUTION_REQUEST).show();
        } else {
            activity.finish();
        }
        return false;
    }
    return true;
}

      

        
        
        
      

    

but it always returns this message "This app won't start unless you update google play services
