Android Question File Read Permisson Denied Or File Not Found Exception?

[RishiKumar2210]

Hi All, I am trying to read the text file in the mobile's package name storage Folder(File.DirDefaultExternal), But it shows following Error

java.io.FileNotFoundException: /storage/emulated/0/Android/data/com.sdmmarketing/files/Registration Details/registrationdetails.txt (Permission denied)

When I connect Mobile with B4a with the same wifi connection It Works. But When I open With connecting, It shows an Error

As Erel already tell to you, you can't use File.DirDefaultExternal
You can use:

Dim rp As RuntimePermissions
Dim MyFolder = rp.GetSafeDirDefaultExternal("")

or

Dim MyFolder = XUI.DefaultFolder

Dim MyFolder = XUI.DefaultFolder

Dim lr_runtimepermission As RuntimePermissions
        lr_runtimepermission.GetSafeDirDefaultExternal("")
        
        If(File.Exists(File.DirDefaultExternal & "/Registration Details", "" )) = False Then

            File.MakeDir(File.DirDefaultExternal, "Registration Details")

            File.Copy(File.DirAssets,"registrationdetails.txt",File.DirDefaultExternal & "/Registration Details", "registrationdetails.txt")

            File.WriteString(File.DirDefaultExternal, "/Registration Details/registrationdetails.txt", ls_jsonstr)
        Else
            File.Delete(File.DirDefaultExternal, "/Registration Details/registrationdetails.txt")

            File.MakeDir(File.DirDefaultExternal, "Registration Details")

            File.Copy(File.DirAssets,"registrationdetails.txt",File.DirDefaultExternal & "/Registration Details", "registrationdetails.txt")

            File.WriteString(File.DirDefaultExternal, "/Registration Details/registrationdetails.txt", ls_jsonstr)
        End If
            
        dialog_progress.dismissWithAnimation
        ToastMessageShow("Registered Successfully", True)

This is My Code.
