DirectoryBind - move data to external_sd ;-)

This is application to bind directories
located on external_sd to directories on
internal memory (/sdcard/). This way You
can transfer large application data
directories to external_sd. Could be
usefull with ex.: games from Gameloft,
other like Shadowgun, applications like


* Requires ROOT !
* Aimed at specific functionality and
features (not idiot-proof)
* You can create any number of Data ->

Target directory pairs, mount them
manually or choose to mount them on
system boot (checkbox does that).

* On/Off switch controls whole mount-on-
boot function.

* Diskette icon indicates if mount
operation was successful, by taping it You
can mount/umount entry.

* Icon changes if application is using
mounted entry

* DirectoryBind can tell what application
is using this entry (tap at entry in use)

* Long tap on entry (disabled) brings edit/
delete window

* App auto umount all entries on USB
connected and remount after USB
disconnected (for now via
BroadcardReceiver UMS_CONNECTED /

* App shows notification and vibrates if
auto umount on USB fails

* If mounting all checked entries (ex. on
boot) app is waiting specified time (def.
60 sec) if data directory is not available
(happens sometimes at boot)

* Tested sucessfully with Asphalt 6,
Shadowgun, DeadSpace, CamScanner
Color statuses:

* GRAY - entry disabled
* RED - mount failed
* BLUE - waiting for data availability
* GREEN - mounted OK

please do not test data transfer files
features on sensitive data they seem to
work OK but are not throughly tested
Compiled using API android 2.3.3.
Attached as self-signed development apk
package. No market link for now.

important info

* Remember ! All entries must be
umounted before attempting to use MASS
STORAGE MODE. Application will try to
do it automatically on USB CONNECT. If
it fails and You'll use MASS STORAGE
MODE sdcard partition WILL CRASH and
reboot will be required to restore normal
operations ! Main cause of that is
appplication using mounted folder. You
have to close that application and retry to
umount entry.

* This application requires *root
privileges* so it has full control over
entire system! Uses root privileges to
invoke "mount", "umount", "lsof" and
"grep" shell commands via su and it
DOES NOT write anything on system
It DOES NOT apply any permanent
changes to the OS, however I cannot
guarantee it does not contain BUGS and
security issues. I'm not responsible to any
damage it can cause. Use it AT YOUT
application permissions explained
application automatically creates target
path, copy existing files from target to
application can perform automatic bind on
VIBRATE - application creates
notification alert with vibrations when
cannot umount all locations on USB

READ_LOGS - dump own logcat to file

*ROOT* - invoking "mount", "umount",
"lsof" and "grep" commands via su


As every program can contain bugs so this
one too. I'm very grateful if someone find
and report a bug. No report will go
unattended and I'll look into each case.
There is just one thing, often report even
very detailed is not enough so application
has built in logging (logcat) capability - it
can be enabled in Preferences.
Logcat can be dumped to file from main
app window: menu -> dump logcat to file
So when reporting bug please attach that
file to Your post
Regards !
