Android Question NET library v1.81 - FTP does it still work? [B4A]

[mash4aa]

Hi
I have a question whether the NET library currently works. I have a strange situation - I tried to connect to 3 different FTP servers and none of them downloaded the file. I don't know if I'm doing everything right. Here is my sample code:

Sub Process_Globals
    Dim FTP As FTP
    'Dim rp As RuntimePermissions
End Sub

Sub Globals
    Private Button1 As Button
End Sub

Sub Activity_Create(FirstTime As Boolean)
    Activity.LoadLayout("Layout")   
End Sub

Sub FTP_DownloadProgress (ServerPath As String, TotalDownloaded As Long, Total As Long)
    Dim s As String
    s = "Downloaded " & Round(TotalDownloaded / 1000) & "KB"
    If Total > 0 Then s = s & " out of " & Round(Total / 1000) & "KB"
    Log(s)
End Sub

Sub FTP_DownloadCompleted (ServerPath As String, Success As Boolean)
    Log(ServerPath & ", Success=" & Success)
    If Success = False Then
        Log(LastException.Message)
    End If
End Sub

Sub Button1_Click
    FTP.Initialize("FTP", "ftp.cpc.ncep.noaa.gov", 21, "anonymous", "")
    Log("Results:" & FTP.IsInitialized)
    FTP.PassiveMode=True
    If FTP.IsInitialized Then
        FTP.DownloadFile("/wd52dg/data/indices/tele_index_nh", True, File.DirRootExternal, "111.txt")
       'FTP.DownloadFile("wd52dg/data/indices/tele_index_nh", True, File.DirRootExternal, "111.txt")
    End If
End Sub

You can connect normally using WinSCP

Manifest file:

'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases.

    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
CreateResourceFromFile(Macro, Themes.LightTheme)
'End of default text.
AddPermission(android.permission.WRITE_EXTERNAL_STORAGE)

You are posting in the wrong forum.

Moved to the questions forum.

Yes, FTP works.

1. Switch to B4XPages.
2. Post the logs.
3. Use Wait For: https://www.b4x.com/android/forum/threads/b4x-net-library-ftp-smtp-pop-with-wait-for.84821/#content

I changed it to "wait for" but nothing still happens. there is nothing in the logs because nothing is happening. I'm sending a new code.

File.DirRootExternal

whenever you see this path you immediately know it is broken.

You do not have access to this folder with targetsdk 33

android.jar / targetSdkVersion / minSdkVersion

There are several versioned components that affect the compilation process and the runtime behavior of our apps. The purpose of this tutorial is to explain the differences between them and help you choose which version to use. Each Android version is mapped to an api level. You can see this...

change this line

    Dim sf As Object = FTP.DownloadFile("wd52dg/data/indices/tele_index_nh", True, File.DirRootExternal, "111.txt")

to this one

    Dim sf As Object = FTP.DownloadFile("wd52dg/data/indices/tele_index.nh", True, File.DirInternal, "111.txt")

1. Note that you were using a WRONG filename (file does not exists!). This is the base of your problem with getting

Error download file

2. Note that i replaced the destinationpath

Logger verbunden mit: samsung SM-G973F
--------- beginning of main
*** Service (starter) Create ***
** Service (starter) Start **
** Activity (main) Create (first time) **
** Activity (main) Resume **
file was downloaded successfully

Can you send me a zip with this improved project? I changed the lines to

Dim sf As Object = FTP.DownloadFile("wd52dg/data/indices/tele_index.nh", True, File.DirInternal, "111.txt")

but something still doesn't make sense to me
I'll see what manifest file you have

 

[mash4aa]

The problem turned out to be the WiFi connection. I enabled the hotspot from Windows 11 to transfer the project in b4a and when connecting to FTP something got stuck and nothing happened. After switching to mobile data, it downloaded the file. Thank you.

And where can you save the file so that you can see it without root on your phone?
