About MicroSD Cards in Android 4.4 / KitKat

When Google launched Android 4.4, they specified that applications you download can no longer write to user-installed MicroSD playing cards. Apps can nonetheless write to inside flash storage. Some devices (like Google Nexus devices) solely have inside storage, and are unaffected. Other gadgets (e.g. Samsung Galaxy and Note devices) have the ability to increase their cupboard space by putting in a MicroSD card. When KitKat is installed on such units, apps are restricted to only having the ability to manipulate information on the built-in storage, with write-access to the MicroSD card being restricted.

This change represents a removal of functionality compared with Android 4.3. 4.3 allowed apps to write down to the MicroSD card, as did prior versions.

The limitation introduced in KitKat does not affect the capabilities of preinstalled apps, solely apps you select to install. Apps preinstalled by Google, your device manufacturer, and your carrier still have this capacity. Only apps that you just choose to put in are restricted.

Technical Details

NextApp SDFix will modify the configuration file situated at /system/etc/permissions/platform.xml to permit apps to write down to the MicroSD card. Specifically, SDFix will add the Android UNIX group media_rw to the WRITE_EXTERNAL_STORAGE permission's configuration. This will enable apps (only people who you granted write entry permissions to when you put in them) to write down recordsdata to the MicroSD card. On many gadgets, this is successfully reverting the state of this permission again to the greatest way it was configured in Android 4.3. This modification is carried out by modifying the present XML file, somewhat than changing it.

A backup of the unique configuration file might be saved at /system/etc/permissions/platform.xml.original-pre-sdfix (provided one does not already exist). Reverting this modification may be achieved through the use of a root -enabled file manager to switch the /system/etc/permissions/platform.xml file with the backed up model.
