Need to change rw permissions to r only on a file located in my documents directory. Have root access yet I am unable to change the file permissions. Tried to change the group to a read only group yet am unable to even change the group. In each case, my root file manager reports it is unable to do so.

As I mentioned in a previous post, I need to change the file permissions to read only in order to force Adobe Reader to prompt the user with a "save as" after completing an Adobe PDF form. Frustrating that it should be this difficult......

Hi

Are you using kitkat and if so, is your documents folder on a removable sd card. If so have a read of this https://plus.google.com/+TodLiebeck/posts/gjnmuaDM8sn There is a solution in there for rooted users.

Thanks. I will check the link provided. The documents folder is not on a removable sd card unfortunately.

(Checked the link. No joy for me...) The file is located on internal storage so I would think it would be a simple change of permissions as root. Grrrrr.....this one thing is the only roadblock to rolling these tablets out........

Adobe reader in android doesnt have a "save as" option. Couldnt you change the file permissions using Windows?
 
Depending on which access path is chosen and if FUSE is used to overlay the file system, it may be impossible for compatibility reasons to change file permissions on a user file.

Regardless of Android version.
 
The kludgy way of doing this is to duplicate the file and then rename it. I am distributing these forms on tablets for our instructors to grade multiple students. Given the varied level of tablet/computer expertise, I want to make it as fool proof and easy as possible.....If I can force a "save as" prompt, it allows the instructor to save a file as "studentname.pdf" and move on to grading the next student.

Still trying to come to terms with root access not being able to make changes...

Tried that. The file is inheriting group/directory permissions from what I see...What the reader does allow, is to copy a file and then rename it.
