User Data Directory In Android 4.3

User data in android 4.2 onwards is stored at /data/user/ But still I found /data/data directory in android 4.3 filesystem. I think it is there to store application d

Solution 1:

No.

/data/data always belongs to the primary user. You can see this by listing /data/user directory:

/data/user/0 is a soft-link to /data/data and the permissions are set so that only this "user 0" has access to all the data stored in /data/data.

Therefore /data/data is not common for all users.
