Can I use MyLocationOverlay with another overlay?

in my app I have an overlay of pins that marks a point of interest. I also want to show the users current location using mylocationoverlay. However when I try to combine the two I get this error from my stack trace and it crashes when I run it on my phone

Here is the code I am using. I have the mylocationoverlay created in the oncreate method and I have the other overlay created in the reload async task

Your exception would not appear to have anything to do with the overlays, but rather with some problem retrieving map tiles from the Google Maps server. Here is a sample project demonstrating both MyLocationOverlay (for the compass rose) and a custom overlay.
