Getting FileNotFoundException (Permission Denied) on saving xml file

I'm trying to save an xml file to a USB device connected to an android device via USB OTG, and I'm getting this exception:

javax.xml transform.TransformerException: java.io.FileNotFoundException: /mnt/usb/filename.xml (Permission denied)

/mnt/usb is the path to the USB device.

If I change the path to something local on the device, everything works.

I read here and tried changing this line:

StreamResult result = new StreamResult(new File( PATH, filename ));

to:

File myfile = new File( PATH, filename );
StreamResult result = new StreamResult(myfile.toURI().getPath());

But the same exception occurred.

On the USB device itself, I can't find any permission configurations, but I can create files in it when connected to PC.

Have you tried with `file.setWritable(true)`? – Héctor Nov 04 '15 at 07:06
have you included WRITE_EXTERNAL_STORAGE permission – karan Nov 04 '15 at 07:08
@bigdestroyer - Didn't work... Same thing – Alaa M. Nov 04 '15 at 07:13
Are you sure that your USB is mounted in /mnt/usb? – Héctor Nov 04 '15 at 07:19
@bigdestroyer Hmm... That might be the problem – Alaa M. Nov 04 '15 at 07:27
