One Tap eMail

luke2012 · Mar 29, 2012

Goodmorning community!
It's possible to send an email using only one tap (send button only) ?

Actually I'm using the intent to send email but the user have to do 2 taps in order to send an email.
It's a nice to have but in certain apps it's important because improve the productivity.

Thanks in advance!

You can use POP3 from the Net library. However you will need to ask the user for their account credentials.

Before all, thanks for your reply!
There is a sample about it ?

Erel · Mar 29, 2012

My mistake. You should actually use SMTP. POP3 is for retrieving mails.

For some reason, it seems to work fine with gmail and not very well with other accounts.

B4X:

'Process_Globals:
Dim SMTP1 As SMTP
Dim server As String    : server= "smtp.gmail.com"
Dim port As Int      : port= 465
Dim emailname As String   : emailname="yourGmailAdress"
Dim password As String   : password="yourpassword"
Dim protocol As String   : protocol="SMTP"
'create
SMTP1.Initialize(server, port, emailname, password, protocol)
SMTP1.UseSSL = True
' sub send:
SMTP1.To.Add (destEmailAdress) 
SMTP1.Subject = "someSubject"
SMTP1.Body = "someText"
SMTP1.AddAttachment(File.DirDefaultExternal, "examle.txt")
SMTP1.Send

For Gmail you should add SMTP.UseSSL = True

Can you encrypt or hide the password in the code? It is exposed in the code for anyone to see. Is this a safe way to send a one touch email? Wouldn't you rather have a couple of steps and protect your password or expose it just to save another click. There are other methods.

Vars are in process globals and you won't see them if you compile encrypted

Compile encrypted?

Newbie question - how do you "compile encrypted"? Can you explain this a bit more? I'm looking to do the same thing and hide the email account password. Thanks.

What lib do I need? I don't see an SMTP Lib in the list.

Thanks...

-------------------------
I found it...the .Net lib.

Ver 1.20 is the latest?

NJDude · Apr 15, 2012

You need to reference the NET library

rfresh · Apr 15, 2012

I got it just now and ver 1.20 is the latest?

I'm getting this error:

java.lang.RuntimeException: Empty writer returned: 530-5.5.1 Authentication Required. Learn more at
530 5.5.1 http://support.google.com/mail/bin/answer.py?answer=14257 k7sm13555772oei.0

The http ref is no longer there.

I did add .INTERNET to my manifest.

Saving password to SQLite record

I wish save the user password in an SQLite db.
There is a safe method to do this ?

Erel · Nov 19, 2012

You can encrypt the password and then save it as a BLOB field. It will not be 100% safe as someone decompile your code and use it to extract the password from the database.

luke2012 · Dec 17, 2012
