When my app loads the following error comes up on some devices. It refers to none of my source files at all! How do I go about fixing this one?

As mentioned here: Marking Current Location on Map, Android and here http://code.google.com/p/android/issues/detail?id=2035, you may need to call overlays.populate(); method in your code.
