Android Question Connecting to USB storage using otg

[Meigionel TS]

I am looking for a way to copy a file from File.DirDefaultExternal to the root folder of any usb storage device connected with the mobile using otg. I looked at the reference codes of the standard USB library to figure out a way but I am struggling and could not figure out. Here is a snippet of the wrong code:

Sub Btn_click
   File.copy(File.DirDefaultExternal, "more.txt", "THE ROOT PATH OF THE USB DEVICE WHICH I COULD NOT FIGURE OUT", "more.txt")
End Sub

I realize that this question has been asked once but not been answered.

I could not understand the process there. Any help?

It is not simple to get the path to a USB storage as there is no API in Android for this.

You should try to run the code posted in this thread. It depends on the USB library.

It is so poorly formatted and I could not understand where to start. I ran into error when I tried that code.

I've ordered an adapter. Will write an example once it arrives. It can take a few weeks.

That would really help. I found that many people raised this question here many times. It would answer all that questions.

Would it be possible to write an example, I am still struggling with this.
