Android Question Newbie Question on JCIF and SMB Libraries

[GGS]

I am an experienced VB6 programmer and new to B4A. I need to be able to copy a file from a shared folder on a PC based lan and display the contents. I've installed SMB and the associated .xml file in the library but have not been able to get JCIFS-1.3.17 to appear in the library tab in the IDE. From the docs. I have read it appears both are needed to copy a file from a shared folder to the Android device. I have copied the JCIFS1.3.17.jar file to the library folder, but no joy. My code for testing this is pretty simple:

Sub Activity_Create(FirstTime As Boolean)
'Do not forget to load the layout file created with the visual designer. For example:
If FirstTime Then
SMB1.Initialize("SMB1")
End If
SMB1.DownloadFile("smb://ROBIN-PC/Genesis/","YourInvoice.txt", File.DirRootExternal,"YourInvoice.txt")

End Sub

Sub SMB1_DownloadCompleted (Url As String, RemoteFile As String, Success As Boolean)
If Success Then
Msgbox (Url, "Success")
Else
Msgbox (Url , "Failed")
End If
End Sub

It always fails. The URL on the PC is shared to Everyone on the network (running Vista, ugh).

Any tips or pointers would be much appreciated.

Thanks,
Gary

JCIFS.jar will not be listed in the libraries. You do not need to select it, it will be added automatically when you check SMB library.

What is the output of Log(LastException) when it fails?

The log doesn't show any exceptions. The log repeats these two lines several times over:

** Activity (main) Create, isFirst = true **
** Activity (Main) Resume **.

This is the log (with Filter off):

I'm running this through the emulator. Does that make a difference? I have also tried this process using a text file in the Public folder on networked PC, but I get the same result.

Thanks,
Gary

Test it with a real device and make sure that the firewall doesn't block the connection.

Hi,

Thanks so much. It was that simple. Works on the actual device.
