What is the alternative implementation of LocationClient in Google Play Service SDK 6.5?

public class MyActivity implements GoogleApiClient.ConnectionCallbacks,                   
                                   GoogleApiClient.OnConnectionFailedListener{
  private GoogleApiClient locationClient;

  protected void onCreate (Bundle bundle) {
    locationClient=new GoogleApiClient.Builder(ctx)
      .addApi (LocationServices.API)
      .addConnectionCallbacks (this)
      .addOnConnectionFailedListener(this)
      .build();
    locationClient.connect();
  }

  // Get the latest current location
  public Location getLastLocation(){
    LocationServices.FusedLocationApi.getLastLocation(locationClient);
  }
}
