Android Question Copy a file and change it's extension (example: from .bat to .txt)

[alvin1929]

Any examples or references that could help me achieve this?

references that could help me achieve this?

the easiest way is: to use File.Copy To copy the File To a new File with the new extension txt , Then use File.Delete To delete the bat File

 

[thinktank]

File.Copy(File.DirAssets,"abc.txt",File.DirInternal,"abc.xyz")

have you not look for file.copy( dir, file.this, dir, file.that )?

Another hack is, instead of copy and delete, you rather read the file into a variable and write it to your new location with the .txt extension

Thank you for your suggestions. I am currently doing the file.copy and file.delete method. I m using the Content chooser with the file.copy, I might be missing something?

Here's my code

Sub Button1_Click

    Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
    If Result Then
    Dim cc As ContentChooser
    cc.Initialize("cc")
    cc.Show("application/bat", "Choose bat ")
    End If
End Sub

Sub cc_Result (Success As Boolean, Dir As String, filename As String)
    If Success Then
    File.Copy(Dir,filename,Dir, "new.txt")
    End If
End Sub

log says
sending message to waiting queue (OnActivityResult)
running waiting messages (1)

Your code cannot work.
Where does this line come from:
Wait For Activity_PermissionResult (Permission As String, Result As Boolean)
?

I miss this line, rp.CheckAndRequest(rp.PERMISSION_WRITE_EXTERNAL_STORAGE)

The code works now and decided to transfer the file in File.DirDefaultExternal

Sorry so to say but all of this is wrong. Watch the runtime permissions video tutorial for more information.
