Erel: The code is easy.
I draw a marker and need to create a circle around to determinate an area.
Depending of zoom you have the image results. The center of bitmap latlon (0,0) is on bottom. And not in the center marker.

    Dim bmd =BitmapDescriptorFactory1.FromBitmap(LoadBitmap(File.DirAssets, "modissat_ch.png")) As BitmapDescriptor
    Dim mo As MarkerOptions
    mo.Initialize
'--------------------------------------------------
    mo.Position2(0,0)  ' same as circle
'--------------------------------------------------
    mo.Icon(bmd)
    mo.Visible(True)

    gmape.AddMarker(gmap, mo)

    Dim  cop As CircleOptions
    cop.Initialize
'--------------------------------------------------   
    cop.Center2(0,0)  ' same as bitmap
'--------------------------------------------------
    cop.Visible(True)
    cop.StrokeWidth(4)
    cop.StrokeColor(Colors.Red)
    cop.Radius(10000)    'if static grow or not like zoom terrain  ,the marker not.
    gmape.AddCircle (gmap, cop)

You should use GoogleMapsExtra library: https://www.b4x.com/android/forum/threads/googlemapsextras.26277/#content

The MarkerOptions object allows you to set the anchor. It should be 0.5, 0.5.
