How to allow apps to delete SD card content I have Android version 5.0 on two different devices and on both, if I delete any user content (e.g. photos, music) stored on the SD card it appears to be removed but moments later reappears exactly as it was.

I am led to believe that this is part of the new OS version enhanced security but is there any way that I can stop this so that when I delete something, it stays deleted! Currently I can only do this via USB from my PC.
Since 4.4 the "WRITE_EXTERNAL_STORAGE" permission no longer grants WRITE access to the secondary(external) sdcard. (This is a simplified explanation, 4.4 did not force this change.)

The necessary permission to do so ("WRITE_MEDIA_STORAGE") is only avialable to system apps.

Since 5.0 it is possible to gain write access through Androids storage provider system, this must be implemented by the developer though.


The native file manager app should be able to write to the external sdcard, check if it requests the "WRITE_MEDIA_STORAGE" permission.
SD Maid will support deletion &amp; renaming with the next update (3.1.2.0+) through the systems storage provider.
I don't know about SandDisk Memory Zone.
