Change color of Custom marker on Map in Android

Question

I'm trying to change the color of markers on Map. I want shape of a common marker but with custom colors. I've tried the following code but it doesn't make any change in color and doesn't give any error as well. Can you please guide any solution or any alternative approach? Any help would be highly appreciated.

Code:

Drawable background = context.getResources().getDrawable(R.drawable.pink_map);
    if (background instanceof ShapeDrawable) {
        ((ShapeDrawable)background).getPaint().setColor(getResources().getColor(R.color.theme_color));
    } else if (background instanceof GradientDrawable) {
        ((GradientDrawable)background).setColor(getResources().getColor(R.color.theme_color));
    }

    // convert drawable to bitmap
    Bitmap bitmap = ((BitmapDrawable) background).getBitmap();

    Marker marker = mMap.addMarker(new MarkerOptions().position(sydney)
                    .title("My Location")
                    .icon(BitmapDescriptorFactory.fromBitmap(bitmap))

Answer 1

This is working for me:

mMap.addMarker(new MarkerOptions()
                    .position(contactLatLng)
                    .title(contactName)
                    .icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_map_blue))
                    );

The important thing is to import the image asset as 'Action Bar and Tab Icons' option. Then you choose the theme CUSTOM and you can select a custom color to apply your image.
