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

I realized that many other my applications need access to SD Card so I fix it once and for all.

 

1) get root access.

2) modify /system/etc/permissions/platform.xml so android.permission.WRITE_EXTERNAL_STORAGE and android.permission.WRITE_MEDIA_STORAGE sections will look like:

<permission name="android.permission.WRITE_EXTERNAL_STORAGE" >    <group gid="sdcard_r" />    <group gid="sdcard_rw" />    <group gid="media_rw" /></permission><permission name="android.permission.WRITE_MEDIA_STORAGE" >    <group gid="media_rw" />    <group gid="sdcard_rw" /></permission>

3) restart phone

 

This fixed my Samsung S4 (but I lost guarantee due to rooting)

“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

Have same error on Samsung S4 with 4.4.2

Syncing of existing folders stoped, also I cannot add sync folder from SD card.
