Android Question send a file from Android device to Windows PC

[mario53]

with an app in B4A I managed to connect a Windows PC via WiFi with Android device.
There is a library that allows you to see the windows PC resources and therefore be able to send a file to a folder.

See here: https://www.b4x.com/android/forum/threads/android-smb-cifs-tutorial.17179/

or with a corresponding B4J app (then you can do even more):

I tried this example, downloaded app in wifi and executed.

This compilation
LogCat connected to: B4A-Bridge: samsung GT-I9301I

debugging gives me this error:
(SmbException) jcifs.smb.SmbException: The network name cannot be found.
----------------------------------------------------------------------------------------
this is the code:

#Region Project Attributes
#ApplicationLabel: B4A Example
#VersionCode: 1
#VersionName:
'SupportedOrientations possible values: unspecified, landscape or portrait.
#SupportedOrientations: unspecified
#CanInstallToExternalStorage: False
#End Region

#Region Activity Attributes
#FullScreen: False
#IncludeTitle: True
#End Region

Sub Process_Globals
Dim SMB1 As SMB
End Sub

Sub Globals

End Sub

Sub Activity_Create(FirstTime As Boolean)
If FirstTime Then
SMB1.Initialize("SMB1")
End If
SMB1.ListFiles("smb://USER-PC/Users/Public/", "")
End Sub

Sub SMB1_ListCompleted(Url As String, Success As Boolean, Entries() As SMBFile)
If Not(Success) Then
Log(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

where the error?

you cannot use your network name. Use the ip instead
I´m not sure but i think the lib is not able to read networknames.

 

[mario53]

What's the syntax for using ip

 

[mario53]

this example and taken in as a functioning network
See here: https://www.b4x.com/android/forum/threads/android-smb-cifs-tutorial.17179/

 

[mario53]

I temporarily solved the problem by giving all permissions to smb library.
so now I see the network and all of SMB1.ListFiles file path ( "smb: // USER-PC / Users / Public /", "")
the problem is if I change path SMB1.ListFiles ( "smb: // USER-PC / temp / test /", "") returns the error
(SmbException) jcifs.smb.SmbException: The network name cannot be found.

thank

Have you tried to access this path with a SMB client (see the tutorial)?

 

[mario53]

which tutorial ?

 

[asales]

Search in the forum to "SMB tutorial".

 

[LucaMs]

which tutorial ?

See here: https://www.b4x.com/android/forum/threads/android-smb-cifs-tutorial.17179/

Erel suggested to try a client, like this one:

Before starting with your own solution it is recommended to download an existing SMB client such as AndSMB: https://play.google.com/store/apps/details?id=lysesoft.andsmb
