Does Chmod work in any directory?? Newbie question

[giga]

:sign0013: I am not able to chmod in any directory or file. I have tried on the mnt/sdcard/XYZ folder no luck.

What is needed to chmod to 755 for a file?
Do you need to mount/ remount the sdcard?

It does not work for /data/data/app-name/files either.

I have tried this as well: http://www.b4x.com/forum/basic4andr...nning-shell-commands-superuser.html#post39820

Any help appreciated.

I can't answer you question - but remember that an SD card is generally formatted as FAT32 and FAT32 has no support for any features of the Linux file system - such a permissions.

Thanks for the reply warwound, I will keep the FAT types in mind. All I am trying to do is put a file in the sdcard or /data/data/my-app/files directory with just RWX permissions.

Strangely, I tried and downloaded a test apk from the web and that one can create a RWX file in their /data/data/their-app/files directory on the same emulator.

?? How can they get access and I can't ??

Just not my app.

P.S I can do it through ADB, but that doesn't solve my problem with each phone.

can't CHMOD bin file in my app-directory

Is there a library similar in B4A. That makes the bin file executable at runtime?

java has this code that works on android

private String MakeExecutable(String filename) {
//First get the absolute path to the file
File folder = m_context.getFilesDir();

String filefolder = folder.getCanonicalPath();
if (!filefolder.endsWith("/"))
filefolder += "/";

String fullpath = filefolder + filename;

Runtime.getRuntime().exec("chmod 770 " + fullpath).waitForExit();

return fullpath;

Any help appreciated. Thanks in advance

This code is equivalent to running chmod with Phone.Shell.
