Custom marker in google maps in android with vector asset icon

Question

How can we achieve a map marker icon with vector asset file, the way google shows it like this, programatically:

Update:

m

You can use this method:

private BitmapDescriptor bitmapDescriptorFromVector(Context context, int vectorResId) {
        Drawable vectorDrawable = ContextCompat.getDrawable(context, vectorResId);
        vectorDrawable.setBounds(0, 0, vectorDrawable.getIntrinsicWidth(), vectorDrawable.getIntrinsicHeight());
        Bitmap bitmap = Bitmap.createBitmap(vectorDrawable.getIntrinsicWidth(), vectorDrawable.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(bitmap);
        vectorDrawable.draw(canvas);
        return BitmapDescriptorFactory.fromBitmap(bitmap);
}

So your code will look like:

map.addMarker(new MarkerOptions()
                .position(latLng)
                .icon(bitmapDescriptorFromVector(getActivity(), R.drawable.your_vector_asset))
                .title(title);

Edit:
In Kotlin it may look like:

private fun bitmapDescriptorFromVector(context: Context, vectorResId: Int): BitmapDescriptor? {
        return ContextCompat.getDrawable(context, vectorResId)?.run {
            setBounds(0, 0, intrinsicWidth, intrinsicHeight)
            val bitmap = Bitmap.createBitmap(intrinsicWidth, intrinsicHeight, Bitmap.Config.ARGB_8888)
            draw(Canvas(bitmap))
            BitmapDescriptorFactory.fromBitmap(bitmap)
        }
    }
