How to add a drawable image in a map marker

Question

I want to add an image into my map marker, I don't know why this code is not working. The marker is not displaying in my current location. Here is the code.

 @Override
    public void onLocationChanged(Location location) {
        BitmapDescriptor imageDrawable = BitmapDescriptorFactory.fromResource(R.drawable.driver);
        if (lastLocation !=null) {
            lastLocation = location;
            LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
            mMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
            mMap.addMarker(new MarkerOptions().position(latLng).title("My Location")
            .icon(imageDrawable));
            mMap.animateCamera(CameraUpdateFactory.zoomTo(10));
        }

Thanks in advance
