[Btsync Can No Longer Sync To Ext Sd Card On Note 3, After Update Android 4.4.2.]

“Starting in Android 4.4, the owner, group and modes of files on external storage devices are now synthesized based on directory structure. This enables apps to manage their package-specific directories on external storage without requiring they hold the broad WRITE_EXTERNAL_STORAGE permission. For example, the app with package name com.example.foo can now freely access Android/data/com.example.foo/ on external storage devices with no permissions. These synthesized permissions are accomplished by wrapping raw storage devices in a FUSE daemon.”

 

So it is possible to sync folders under the Android/data/<btsync_package>/

Need only to know btsync package.

 

Update:

I found package name - com.bittorrent.sync

But btsync still throws error when I try to sync folder under /Android/data/com.bittorrent.sync

 

It worked for me on an S4 with KitKat, syncing to /storage/extSdCard/Android/data/com.bittorrent.sync/docs, where 'docs' is a name I chose.
