Access to Garmin Descent MK1 USB storage on Android

[Wojciech Więckowski]

Hi,

I wonder if it's possible to provide folder selector dialog in Subsurface
Mobile to access Garmin FIT files when OTG cable connection is used.

MK1 storage is mounted automatically by the system and FIT files are
accessible from Android file manager.

From Subsurface I can set vendor + model using two combos but "Connection"
combo shows only FTDI option and a lot of MAC addresses.
It would be nice to have at least a possibility to enter raw mount path
which in my case is:
/storage/DC51-1EC5

I assume that Garmin parser works also on phones but probably hasn't been
tested yet.

I have thought about this but then got distracted. I don't know which permissions Subsurface-mobile on Android would need to get access to mounted filesystems and if we could get an Intent that tells us where the Descent is mounted - but this certainly seems doable. I just don't think I'll have time to look into this any time soon.

I am sure that this would work

Probably getting mount path is relatively easy as access to /proc/mounts
shouldn't be restricted by android and only vfat volumes are possible
storage candidates. Reading files from the removable storage will need all
the platform-specific stuff.
