In Android project, Why It is fail to mark the location whose latitude and longitude are got from other classes

it is fail to mark LOCATION2 on map , but is successful if replace it using LOCATION1.

    public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;
        LatLng LOCATION1 = new LatLng(18.79038, 98.98468);
        int permissionCheck = ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_CALENDAR);
        mMap.setMyLocationEnabled(true);
        mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(LOCATION1, 13));
        vehicles=query.QueryVhe();
        Double lat=vehicles.get(0).getLatitude(); //get latitude.
        Double lng=vehicles.get(0).getLongitude();//get Longitude.

        //I am sure that lat and lng have already got data here.
        //here is a problem that it is fail to mark LOCATION2.
        LatLng LOCATION2 = new LatLng(lat, lng);
        mMap.addMarker(new MarkerOptions()
                .title("Sydney")
                .snippet("Chaing Mai.")
                .position(LOCATION2));// But if it is successful if LOCATION2 were LOCATION1.
    }
}

You can add your marker in following manner.

    Marker marker = map.addMarker(new MarkerOptions()
           .position(new LatLng(37.7750, 122.4183)) // those are dummy values for lat and long
           .icon(BitmapDescriptorFactory.fromResource(R.drawable.location))
           .title("My Location on Map")
           .snippet("details"));

use this code if it helps you please make it as right

 mMap.addMarker(new MarkerOptions()
                        .title("My Location")
                        .icon(BitmapDescriptorFactory.fromResource(R.drawable.myloc))
                        .anchor(0.0f, 1.0f) // Anchors the marker on the bottom left
                        .position(new LatLng(lat, lon)))
                        .setDraggable(true);

if you dont need anchor or setdraggable you can remove it
