Thank you for the quick answer Dianne. It confirms that I'll just have to
include another implementation of SMTP into my app.
Though I still think it would be nice if could set up an Intent, loaded with
the proper information in an attached bundle that would specify the email
account, the account authentication, and the message body. Which would be
handled by an application that the user had configured as the default email
handling application without user intervention. Hmmm, actually this might make
an interesting little project to continue my Android education.
Understand it's not possible at the moment though, through standard
resources......
Best,

I have been following this thread with some interest. Since I also want to
be able to send an email without any user intervention. Now before anyone
says that should not be possible since it would be a security problem, let
me point out that I can send an SMS message without user intervention, if I
have the permissions set properly. So I would expect that I would also need
to set permission to allow sending email as well.
There is only one way SMSs can be handled. On the G1 there are two e-mail
clients built in to the system, one of which can have multiple accounts. You
CAN NOT send an e-mail without the user being involved, period, because you
simply have no way to know how that e-mail should be sent.
If you want to send an e-mail, you need to have the code for doing so in your
app, and have the user specify the account information for it.
I have been poking around a bit in the source code and found this in the
stock Android email app:
package com.android.email.mail.transport;
/**
* This class handles all of the protocol-level aspects of sending messages
via SMTP.
*/
public class SmtpSender extends Sender {
public static final int CONNECTION_SECURITY_NONE = 0;
public static final int CONNECTION_SECURITY_TLS_OPTIONAL = 1;
public static final int CONNECTION_SECURITY_TLS_REQUIRED = 2;
public static final int CONNECTION_SECURITY_SSL_REQUIRED = 3;
public static final int CONNECTION_SECURITY_SSL_OPTIONAL = 4;
private Transport mTransport; 53 String mUsername; 54 String
mPassword;
..........
/** Allowed formats for the Uri:
* smtp://user:passw...@server:port CONNECTION_SECURITY_NONE
* smtp+tls://user:passw...@server:port CONNECTION_SECURITY_TLS_OPTIONAL
* smtp+tls+://user:passw...@server:port CONNECTION_SECURITY_TLS_REQUIRED
* smtp+ssl+://user:passw...@server:port CONNECTION_SECURITY_SSL_REQUIRED
* smtp+ssl://user:passw...@server:port CONNECTION_SECURITY_SSL_OPTIONAL
*
* @param uriString the Uri containing information to configure this sender
*/
public SmtpSender(String uriString) throws MessagingException {
...........
Which seems to have public methods to send email.
You are looking in the e-mail app. There is nothing public here at all. It is
just internal implementation of the application. It doesn't matter if it makes
a class public in its internal implementation, it is still internal, and
nothing you can use.
As I understood the
philosophy behind building Android apps, which is to reuse
public Intents and methods to allow the scarce available memory to be
leveraged as much as possible.
Yes, there are intents for using parts of an application that they want to
allow others to access. There is no standard intent for "send an e-mail
without the user being involved," and I don't expect there to be such a thing
any time soon if at all. Some specific e-mail application may define its own
intents to use for that, but this would be specific to that app, so you would
need to know about it yourself. (And if multiple apps were to support this,
you would still need to have the user involved to decide which app to use, and
possible which account in that app to use.)
So the question is: Can we use the existing code to send email in the stock
Android email app? Or is that sort of thing frowned upon?
It's not possible.
