This fix Requires ROOT and Busybox installed to /system/xbin
Context: I have been looking for a way to make an app that hides files to read/write files on my external SDcard, The way I found was to edit the platform.xml file to add that missing line as guided here: LINK this is just one of the many articles saying the same thing. which helped some apps work, but not the one i was looking for.
Reason: the point of this script is to make it so you do not have to set permission to the "media_rw" folder after every reboot manually.
Steps:
1) Follow and complete guide linked above, or any other similar guide, if you have not done so already.
*NOTE* some custom ROMs have already implemented this fix
2) After reboot use an app that allows you to make scripts (Ex. Rom Toolbox) this guide will use Rom Toolbox app
- create new script, name it whatever you want. I named it "sdcard permission"
- input this line and save:
*NOTE* you do not need to put it as 777 but it is what worked for me as it gave full read/write/execute permissions
3) Set script to run at boot
4) Run script manually then check app to see if it worked
-Alternatively go check /mnt/media_rw to see if it has the new permissions
Now you should be able to access the external SD card after every boot.
NOTE: you may need to redo the guide in the first step after switching ROMs as the new ROM may not have the fix implemented.
