I am an avid outdoorsmen and I have downloaded a few different gps apps to my droid. Like My Tracks, Oruxmaps, Trekbuddy, Geobeagle, and so on. I cannot figure out for the life of me how to download an offline map to put on these apps so that I may use the gps feature when I have no signal. Can someone please help me out with all of this? I'm about to go crazy here.
