아래와 같이 코드를 작성했습니다. 하지만 화면에서는 현재 위치를 확인 할수 있는 아이콘이 안나옵니다... ㅠㅠ 살려 주세요 고수님들 ㅠㅠ

public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

    private GoogleMap mMap;
    FusedLocationProviderClient client;
    int permissionchek;

    LocationCallback mLocationCallback;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
        client = LocationServices.getFusedLocationProviderClient(this);



    }

    @Override
    public void onMapReady(GoogleMap googleMap) {
        mMap= googleMap;

        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED &&
                ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
            mMap.setMyLocationEnabled(true);
            mMap.getUiSettings().setMyLocationButtonEnabled(true);
        }
        mMap.getUiSettings().setMyLocationButtonEnabled(true);
        mMap.getUiSettings().setZoomControlsEnabled(true);
        try{
            mMap.setMyLocationEnabled(true);

        }catch(Exception e)
        {

        }




    }

    private void setPermission(){
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED &&
                ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

            ActivityCompat.requestPermissions(this,
                    new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION}, 1);
            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, 1);
            return;
        }
    }
