startLocationService()가 없다고 뜹니다.

Question

import android.content.Intent;
import android.location.Location;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.model.LatLng;

public class MainActivity extends AppCompatActivity {

    private Button btn[] = new Button[3]; // btn_Howto 클릭시 이벤트
    GoogleMap map;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btn[0] = (Button)findViewById(R.id.btn_whyBeep);
        btn[0].setOnClickListener(new View.OnClickListener(){
            public void onClick(View v) {
                Intent intent = new Intent(MainActivity.this, WhyBeep.class);
                startActivity(intent);
            }
        });

        btn[1] = (Button)findViewById(R.id.btn_Howto);
        btn[1].setOnClickListener(new View.OnClickListener(){
            public void onClick(View v) {

                map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

                startLocationService();
            }

            public void onLocationChanged(Location location) {

                showCurrentLocation(latitude, longitude);
            }
            private void showCurrentLocation(Double latitude, Double longitude) {
                LatLng curPoint = new LatLng(latitude, longitude);

                map.animateCamera(CameraUpdateFactory, newLatLngZoom(curPoint, 15));

                map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
            }
        });

        btn[2] = (Button)findViewById(R.id.btn_Setup);
        btn[2].setOnClickListener(new View.OnClickListener(){
            public void onClick(View v) {
                Intent intent = new Intent(MainActivity.this, SetUp.class);
                startActivity(intent);
            }
        });


    }
}

지금 이런 상태인데 

startLocationService(); 이 메소드가 없다고하고

showCurrentLocation(latitude, longitude); 안의 인자가 없다고하고

map.animateCamera(CameraUpdateFactory, newLatLngZoom(curPoint, 15));

이것 역시 인자가 없다고 뜨는데 import를 더 해야하는 건가요?
