I have an off line map of Australia which I downloaded from mapsforge.org. It works well and is detailed enough for my needs.
However when I try to load another map eg Online Google - Bing Maps or OSM - Outdoor maps - the title of the map changes to that map, but the actual map on the screen remains the Australian mapsforge map.
On one occasion I could see the new map starting to load on the screen, but then it just flicked away and the Australian mapsforge map came back.
Can someone explain what I may be doing wrong or what is happening?
