What kind of possibilities do I have? I would like to use GPS and custom map-sources, but offline. First I thought about the OSMDroid library with own map-sources. But one cannot use it offline. My second idea was to use a simple graphic and make it geo-sensitive? How could I make a graphic geo-sensitive? Could anybody please give me some hints? Are there other opportunities to realize something like I want to?
thank you for your answer! I also need to know how to make my own graphic geo-sensitive! That means: I would like to use any graphic and mark my position on it. How can I realize the positioning? I need somehow to know where the received longitude and latitude on my graphic are. Has anybody already dealed with something like that and could help?
