Why eclipse can not resolve com.google.android.gms.location.ActivityRecognitionClient?

Question

1. I want to use google ActivityRecognition service in my android application.
2. I've install google play services from SDK manager and add google_play_services_lib project to my project by import option and hitting "copy project to your workspace" checkbox.
3. I'v been wrote a code according to this link: Android Activity Recognition not working with Nexus 5

4. My import list is as bellow:

   import android.app.PendingIntent; import android.content.Context; import android.content.Intent; import android.hardware.Sensor; import android.hardware.SensorEvent; import android.hardware.SensorEventListener; import android.hardware.SensorManager; import android.os.Bundle; import android.support.v4.app.FragmentActivity; import android.util.Log; import android.widget.Toast;

   import com.google.android.gms.common.ConnectionResult; import com.google.android.gms.common.GooglePlayServicesClient; import com.google.android.gms.common.GooglePlayServicesUtil; import com.google.android.gms.location.ActivityRecognitionClient;

   public class MainActivity extends FragmentActivity implements GooglePlayServicesClient.ConnectionCallbacks,GooglePlayServicesClient.OnConnectionFailedListener {

5. My android project can resolve all import excepting com.google.android.gms.location.ActivityRecognitionClient!!!!

6. I copied sample activityRecognition project from developer.android.com and open it from my eclipse but there is the same problem with ActivityRecognitionClient!!!
7. I found a similar problem here: Imported Project in Android Studio can't resolve ActivityRecognnitionClient but not helpful for me.
