Android Question File not exist

[Almog]

Hello,

I tried to use OkHttpUtils2 to download a file from a link (trying to download file named "rec.zip")

        Dim d As HttpJob
        d.Initialize("", Me)
        d.Download(link)
        Wait For (d) JobDone(d As HttpJob)
        If d.Success Then
            If Not(File.IsDirectory(File.DirRootExternal , "/rec")) Then
                File.MakeDir(File.DirRootExternal, "rec")
            End If
            Dim out As OutputStream = File.OpenOutput(File.DirRootExternal & "/rec" , "rec.zip", False)
          
            File.Copy2(d.GetInputStream, out)
       
            out.Close
        End if

and get an error :
