Can you please help me summarize file access issues on KitKat+? I have mixed impression on what works and what does not.

- can DataDir point to a folder on SD card - ie. can TB save new files to SD card?
- if DataDir points to internal memory, are the files created by TB (wpts, tracks) visible from PC when the phone is connected as mass storage device?

Or, what setup is working for you guys with 4.4+? Cool

Case - micro SD moved from old phone to new KitKat based device, existing folders Smile
Data dir on SD doesn't work, no permissions for app to save wpts, tracks, etc.
So app folders should be created in internal SD, maps can work from external SD (but tmc files are not created for new maps).
Price - going to maps folder on SD, to select something else, is more complicated (lot of steps in file system).
Tracks or wpts can be transfered between internal memory and ie micro-SD, using phone built-in file manager or others, no problem with file access.
As I remember micro-SD was visible only from PC for cable connection, but it depends on USB mode and installed apps; doesn't matter when ie cloud/WiFi file manager is used in phone.
Edit: both SD are visible for cable connection, when no PC app used Smile Including all TB files. MTB mode for USB used.

On my SGS3, running rooted 4.4.4, newly recorded tracks were not visible from the PC through usb. (Existing Trekbuddy file structure copied from a backup to the external sd-card - had no problems while using Trekbuddy.)

I will also test on my Nexus 7, which has only internal storage.

Just bought a Motorola MotoE which uses KitKat and also could not find the directories so ended up using Filezilla to ftp the files onto the device. I used File Manager app and under Network is a Sharing tab that gives an IP address to use, ie, 192.168.0.4:2121.

Some applications can WRITE to SD card i my XPERIA Z3 Compact without root access. For example OSMAND, MAPY.cz ...

according to: http://forum.xperia.cz/viewtopic.php?f=41&t=10218

Application can write to folder created by this apllication.

Application needs WRITE_EXTERNAL_STORAGE permission.
( Other •modify/delete internal media storage contents ??)

I think that application should write to /sdcardx/Android/data/ folder.

Is it possible to check TrekBuddy's permissions?
