B4A Library New Net library - Android FTP, SMTP and POP3

Status
Not open for further replies.
The Net library supports FTP, SMTP and POP3 protocols. This library replaces the FTP library. Both regular connections and SSL connections are supported.
SMTP - Allows to directly connect to SMTP mail servers and send mails, including Html messages and attachments.
POP3 - Allows to directly connect to POP3 mail servers and download messages. Currently the messages are not parsed. The raw string is returned. You can use MailParser class to parse the raw messages.

Installation instructions:
- Download the attach file.
- Copy Net.xml and Net.jar to the additional libraries folder. Make sure that there are no older copies in the internal libraries folder.

V1.81 - latest version
V1.80 - SMTP, POP and FTP can be configured to use a custom trust manager. This allows accepting invalid certificates.

V1.77 - New Sender.MailFrom field. Allows setting the mail address that is sent with the MAIL command. By default it is the same as the Username field.

V1.75 - Adds a configurable timeout parameter - FTP.TimeoutMs. Default timeout is set to 60000 (60 seconds).

V1.70 - Adds support for calling with Wait For: https://www.b4x.com/android/forum/threads/b4x-net-library-ftp-smtp-pop-with-wait-for.84821/
SMTP.AdditionalHeaders map. Allows adding headers to the messages.

V1.63 - Fixes an issue with SMTP mails with attachments. The closing boundary was previously missing.
V1.62 - Fixes an issue with SMTP in StartTLS mode.
V1.61 - Fixes an issue in SMTP related to the content encoding not being set in multipart messages.

V1.60 - New method: FTP.AppendFile. Similar to UploadFile. Appends the data to an existing file if such exists. It sends the APPE FTP command.

V1.53 - Fixes an issue with FTP.CloseNow and SSL connections.

V1.52 - Adds support for different types of authentication methods (SMTP): http://www.b4x.com/android/forum/th...d-ftp-smtp-and-pop3.10892/page-11#post-232432

V1.51 is released. Fixes an issue with FTP over SSL explicit mode.

V1.50 is released. See this link: http://www.b4x.com/android/forum/th...d-ftp-smtp-and-pop3.10892/page-10#post-231145

V1.37 is released. This version removes the automatic escaping of '=' characters in SMTP messages. To implement it in your code you should write:
B4X:
SMTP.Body = SMTP.Body.Replace("=", "=3D")


V1.35 is released. This version adds support for STARTTLS mode.
Unlike UseSSL mode the connection is "upgraded" to a secured connection only after the client sends the STARTTLS command.
Most of the popular smtp servers support this mode, usually on port 587.

B4X:
Sub Activity_Create(FirstTime As Boolean)
   If FirstTime Then
      smtpClient.Initialize("smtp.gmail.com", 587, "[email protected]", "yyy", "SmtpClient")
      smtpClient.StartTLSMode = True
   End If
End Sub

How to obtain the Success parameter???

"public_html/PublicPhotos/Products/20150224132632.jpg, Success=true " <- This is what appeared in the log after the FTP process..

Below is my code for uploadcompleted... A failure message will show if it is not successful and other functions will run if it succeeded.. And when I ran it, no failure message was shown and the next function was started..

Sub FTP_UploadCompleted (ServerPath As String, Success As Boolean)
Log(ServerPath & ", Success=" & Success)
If Success = False Then
ToastMessageShow(FailMsg,False)
Activity.Finish
End If
If Success = True Then Functions(2)
End Sub

Please use [code]code here...[/code] tags when posting code.

Success is true in this case. This means that the file was uploaded successfully.

But the file is somehow damaged during the process.... why is that??

Are you enabling SSL and tls? I use port 587 for gmail connections and it works well.

B4X:
 If MyAuth.CamPort = "587" Then
                       SMTP.StartTLSMode = True
                    SMTP.UseSSL = MyAuth.CamSSL
               Else
...
