Question

I want to create a folder in sdcard in an android device and I want to set a folder permission for the creating folder. The folder permission should be that from only from m

Answer 1

as others have said, you can't for the reasons specified.

i'm not exactly sure what you are trying to accomplish, but if you want to create a private file that can't be accessed by other apps, you can create in your app's "data" directory, by doing this,

OutputStream os = context.createFileOutput("myfile.ext", Context.MODE_PRIVATE);

note that this is not the SD card, it's internal storage, so you aren't going to be able to create a very large file.

Answer 2

String SaveFolder = "/Ready";
String extStorageDirectory = Environment.getExternalStorageDirectory().toString();
File myFolder = new File(extStorageDirectory + Folder);
myFolder.mkdir();

This is a code to make a folder, and just like Tim said: it is not possible to create read-only permissions folder.

Answer 3

sadly it is not possible to create read-only permissions for the sdcard. This is a part of Android's system design and won't be changed soon.

Answer 4

I am making an application in android and I want to make a ready only folder in sdcard.

This is not possible, sorry.

Answer 5

FAT32, the standard SD card file system, does not support file permissions. This means that any file is world readable and world writeable.
