Write access on the external SD card (where most users will want to store their data) is only possible in the app's own folder or everywhere if the phone is rooted.
I'm afraid it's not possible. Run.GPS needs write access to the routes folder since it also stores downloaded route files there. Therefore, it should be in the app's own data folder to have full read/write privileges.
Is it possible to configure where route files are stored? I would like to change it into my downloads dir- it is very useful when I download gpx from web site.
It is not necessary to do it in app, i can change it manually in config file..
