I recently came across this problem. The issue is outlined in this bug report.

To fix it you should call populate() in your ItemizedOverlay before any data is populated. I added it to the constructor:

private class MyItemizedOverlay extends ItemizedOverlay {

    private Context context;
    private ArrayList mOverlays = new ArrayList();

    LocationItemizedOverlay(Drawable defaultMarker, Context context) {
        super(boundCenterBottom(defaultMarker));
        this.context = context;
        populate(); // Add this
    }
}
