hi i got this error when try use gmail with Net library.

java.lang.RuntimeException: Empty writer returned: 530-5.5.1 Authentication Required. Learn more at
530 5.5.1 https://support.google.com/mail/answer/14257 z12sm2426015pbt.73 - gsmtp

i have enable "less secure" in my google account but still no luck. Does google require advance auth system? here is my code.


B4X:
Dim theSmtp As SMTP
    Try
        Dim TextReader1 As TextReader
        TextReader1.Initialize(File.OpenInput(File.DirInternal, "save_config_email.txt"))
        rxMail = TextReader1.ReadLine
        txMail = TextReader1.ReadLine
        mailPassword = TextReader1.ReadLine
        TextReader1.Close

        theSmtp.Initialize("smtp.gmail.com",465,"[email protected]","password","SMTP")
        theSmtp.UseSSL = True
        theSmtp.Subject = "Android Security Lock System"
        theSmtp.To.Add(rxMail)
        theSmtp.Body = "Your phone last detected add " & lat & " , " & lon & " Attachment is picture taken from front camera."
        theSmtp.AddAttachment(dir,filename)
        theSmtp.Send()
    Catch
       Log(LastException.Message)
    End Try
