Hello,
I'm not sure if this is the right place to ask. I'm trying to build an app that can create waypoints and save them to an .gpx file. I'm able to get the location, but now I want to create .gpx files and edit them. I also want to be able to access the files when I'm on my computer, so the folder need to be accessible. Could someone please explain to me how I can do this, or tell me where I can find how to do this? Tanks
