What is this?
Hi all,
This is a script that will allow you (with your 4.2.x ROM) to bind the data from any app or game from /sdcard/Android/data to extSdCard. This means, your internal memory is no longer being filled by 6 Games (and their respective data) on the 16 GB versions of the S3.
Hasn't this been done before?
Yes and no. Back in the 4.0.4, 4.1.1 and 4.1.2 days, we could all use an app called "Directory Bind" but this no longer works in 4.2.x because Google have changed the way this works (Permissions). What happens now, is only the app that creates the bind can see it. For example, if you bind one directory to another using terminal, if you cd to the original location, do an "ls" list command and it will list you the data in the new location. However, browse to the original location in a file manager, it will be empty.
So this script works?
Yes it does. It uses what is unfortunately an "ugly" work around, by hijacking a system processes (debugger daemon) to achieve elevated permissions (Above and beyond that of su).
The script is still very much a "Work in Progress". I would even call it a proof-of-concept at this point. It will be tidied up and made more user friendly as time goes on. Right now though, I'm just happy to have it working.
Is this the only way?
No it is not. There are ways of changing the Dalvik cache or patching init.rc and various other technical methods that have found their way into AOSP / CM based roms. This is a way to achieve that on a stock rooted setup (Touchwiz) without high detail patching that the normal root user may not be in a position to do.
Any limitations?
How does it work?
We have in the attached zip, 2 scripts. 1 manages the set up of your defaults and mounts. The other does the daemon hijacking. The 1st calls the second script when a new mount is added (although I haven't confirmed this 100% working yet).
Script manager to be used to call the primary script but also it can be used to call the secondary too. The hijack needs to occur at every boot too.

- It assumes that for app data, you will have one named directory you bind everything to. For example, I have the default set as /extSdCard/bind. The script creates my new app directories within there, then binds the original over to it.
- You have to set your defaults on first use before you can bind.
- It uses script manager to run and manage the scripts.
- There is not yet a way of reversing a bind through the script. It can be done manually however. Scope for future.
- The option to select defaults, in the terminal display is not a single column, which makes it tricky to see. You need to go to landscape mode for a better view.
- Very few games have a hidden folder starting "." - These cannot be bound (copy issue)
