Whenever you see code with File.DirRootExternal or Msgbox you immediately know that it is broken. Use the forum search and you will find many many threads about these two.

my problem is only with the line:
File.Copy(Dir, FileName, File.DirRootExternal, "PDFtest.pdf")
which does not copy the file, which gives the error:
The error: (Exception) java.lang.Exception: java.io.FileNotFoundException: /storage/emulated/0/PDFTeste.pdf: Failed to open: EPERM (Operation not allowed)

it is not an authorization problem, the problem is that ContentChooser returns the Dir and when I try to copy the file does not exist, am I being clear?

Nothing to say until you fix it.

You cannot use File.DirRootExternal.
You have to use rp.GetSafeDirDefaultExternal("subfolder")

Replace msgbox with
MsgboxAsync("Error msgbox","")

 

[Erel]

ou have to use rp.GetSafeDirDefaultExternal("subfolder")

Tip: don't use it as well. Use FIle.DirInternal or XUI.DefaultFolder.

 

[zed]

I use rp.GetSafeDirDefaultExternal("subfolder") in development mode.
It allows me to check if all the files are well copied, which is not possible with xui.DefaultFolder then,
I change rp.GetSafeDirDefaultExternal("subfolder") for xui.DefaultFolder.
Is this a bad thing?

 

[Erel]

It allows me to check if all the files are well copied, which is not possible with xui.DefaultFolder then

Why not? Don't confuse File.DirInternal=XUI.DefaultFolder with File.DirAssets.

Anyway, there is nothing bad with using GetSafeDirDefaultExternal, it is just not needed any more and doesn't provide any benefit.
