Android Google Maps - custom background behind all markers

Question

I try to put a background between the map and my marker; this image should always (!) stay behind all markers.

I tried several way, e.g. showInfoWindow() on all my markers except the background image, but it seems as this would only help for the last one.

Then I tried a solution using GroundOverlay, but I need my image to always stay the same size (e.g. half the device size), independent of zoom factor.

Is there a solution on Android for this?

This is easy to do.

Add two markers instead of one. First add the background as a bitmap at lat_lng.

Something like this:

map.addMarker(new MarkerOptions()
      .position(lat_lng)
      .anchor(0.5f, 0.5f)
      .icon(BitmapDescriptorFactory.fromBitmap(bitmap)));

Then add your marker like you normally do at the same lat_lng.

Do the above for each of your markers.
