Understanding “Permissions”

On any UNIX or Linux based file system, every single file and folder stored on the hard drive has a set of permissions associated with it. These permissions which are also called attributes, determine the level of accessibility/permission given to a user or a group of users.


The Read-Write-Execute attributes tells the system or server who is allowed to do what with a particular files. In the same way, every file and directory also has an OwnerGroup and Others associated with it. By changing these permission rules, you can direct a system or server what king of accessibility it allows to different types of peoples.


Android, being a Linux-based platform for mobile devices, also relies on this kind of permission rules in its system files. And therefore, you might need to fix/manage or edit them in certain situations.

  1. Copy the file/apk  that you want to fix permissions of and copy it to your devices’  internal or external SD Card.

  5. To fix or set Read-Write-Execute (r-w-e) permissions of  the file, you must copy it to a root directory (like system, data, etc.) first. You cannot fix permissions while the file is stored on SD or ExtSD card on your device.

In short, we mention this rule simply as rw- r– r– where each blank space shows unmarked attribute.
