Android Question Network Login to Windows PC Shared Folder

A Z M JANNAT UL KARIM · Jul 22, 2019

Hi, I am using an apps in local computer which will access some images from network URL like \\192.168.0.22\image$\image01.jpg and put in some label. But the shared folder can only be access through some login credential. Can I use any Login credential from Apps before accessing the file. Thank you

The SMB library allows you to access Microsoft Windows Network file system.

should be possible with a SMB library

SMB-Version 3.1.1 > Windows 10 / Windows Server 2016 / Samba 4.3

For Information the folder is in Windows 10 v1903 System. Had turn off password protected sharing. Folder shared with Everyone / Read Only. Also had SetCredentials for it. Following is the code for your reference ...

B4X:

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    'Activity.LoadLayout("Layout1")
    If FirstTime Then
        SMB1.SetCredentials("user","123456","")
        SMB1.Initialize("SMB1")
    End If
    SMB1.ListFiles("smb://192.168.2.246/images/", "")
End Sub

Sub SMB1_ListCompleted(Url As String, Success As Boolean, Entries() As SMBFile)
Log("ListCompleted")
' Return
  If Not(Success) Then
      Log("ListFiles failed : " & LastException)
  Else
    For i = 0 To Entries.Length - 1
        Log("*****************")
        Log(Entries(i).Name)
        Log(Entries(i).Directory)
        Log(DateTime.Date(Entries(i).LastModified))
        Log(Entries(i).Parent)
        Log(Entries(i).Size)
      Next
  End If
End Sub

Thank you ...

Can you please tell me which PORT need to check. I can access from other PC through the URL with Credentials.

MarkusR · Jul 22, 2019

maybe 445
you can see open port in cmd window with
netstat

Try it with this library: https://www.b4x.com/android/forum/threads/jcifs-ng-smb-client-smb2.104560/
It support SMB2/3

Great Don. Now it can access the shared folder and list all the file from there

Thank you very much ...
I think I need to go through the documentation to further implement it
