Android Question Email sending by Net, SMTP

[Vili]

I am trying to make email sending work:

Sub Button1_Click

xui.MsgboxAsync("Hello world!", "B4X")
smtpClient.Initialize("smtp.gmail.com", 587, "xxxxx@gmail.com", "xxxxxx", "SMTP")
smtpClient.StartTLSMode = True
smtpClient.To.Add("xxxxxx@gmail.com")
smtpClient.Subject ="Test subject"
smtpClient.Body ="TestingBody"
smtpClient.Send

End Sub

I display that MsgBox first, so the function works. I added the net library. No error message, email is still not sent. Can anyone help? I am a beginner in B4A.

Thank you, Vili
PS: Developing just for myself

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

You need to wait for the MessageSent event and check for errors: https://www.b4x.com/android/forum/threads/b4x-net-library-ftp-smtp-pop-with-wait-for.84821/#content

Sorry, I formatted below. I tried to follow what you wrote but MessageSent does not get triggered... I don't get any window pop up. Can you fix my code?
Thank you

Private Sub Button1_Click
    xui.MsgboxAsync("Hello world!", "B4X")
    smtpClient.Initialize("smtp.gmail.com", 587, "xxxxx@gmail.com", "xxxxxx", "SMTP")
    smtpClient.StartTLSMode = True
    smtpClient.To.Add("xxxxxx@gmail.com")
    smtpClient.Subject ="Test subject"
    smtpClient.Body ="TestingBody"
    Dim sf As Object =      smtpClient.Send
    Wait For (sf) MessageSent (Success As Boolean)
        
    If Success Then
        xui.MsgboxAsync("OK", "B4X")
    Else
        xui.MsgboxAsync("Error", "B4X")
    End If
End Sub

 Wait For (sf) SMTP_MessageSent (Success As Boolean)
If Success Then
  Log("ok")
Else
 Log("error: " & LastException)
End If

Erel: many thanks! With logging I could see that it is an auth problem. I had to set up an App password for my GMail account

BTW, I bought B4A in Dec 2013 (info at macasoft dotttttttttt hu. I played with it a little, now will learn in details.

Thank you!
