Android Question How to write on a USB-Stick

[peternmb]

Hallo,

i want to export a file on a USB-Stick.

I made a litte example where I can choose in the filebrowser the USB-Stick, but i find not the right way to write the file.
Please can somebody tell me, where I made the mistake?
Thank you.

The only way is to use streams and the methods in ExternalStorage class. File.Copy will not work as you cannot use normal File operations on external storege.

Thank you for this answer.

If I use streams it is the same - I can not write to the stick.
I modified my example and use streams.

See above and the example here.
