Is it possible to open the email app and specify path to a file on the file system as attachment? I need to do this from my app.

I know I can open the app with predefined body, subject etc. but I want to know about the file attachments.

I also know that I can do this programatically from my app but I want to take advantage of the nice UI the mail app provides instead of implementing custom forms from my app.

No, this is not supported.

you can make this,

please try this code.

    PNGEncodedImage encoder = PNGEncodedImage.encode(b);
                byte[] stream = encoder.getData();

                String messageData = "See attachment: " + "test.png";

                if (stream == null || stream.length == 0) {

                }
                String mmtype = MIMETypeAssociations.getMIMEType("icon.png");
                Dialog.alert(mmtype);

                mp = new Multipart();
                SupportedAttachmentPart sap = new SupportedAttachmentPart(mp,
                        mmtype, "icon.png", stream);

                TextBodyPart tbp = new TextBodyPart(mp, messageData);
                mp.addBodyPart(tbp);
                mp.addBodyPart(sap);
                Folder folders[] = Session.getDefaultInstance().getStore()
                        .list(Folder.SENT);
                message = new Message(folders[0]);
                Address[] toAdds = new Address[1];
                try {
                    toAdds[0] = new Address("omar.hassan@asgatech.com", "omar");
                    message.addRecipients(Message.RecipientType.TO, toAdds);
                    message.setContent(mp);
                    message.setSubject("Message with attachment " + "icon.png"
                            + ".");

                    Invoke.invokeApplication(Invoke.APP_TYPE_MESSAGES,
                            new MessageArguments(message));

                } catch (AddressException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } catch (MessagingException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

Right, you can create a message to send with an attachment and use that when invoking the messages application.  

I understood the requirement as opening an email message and view its attachment in the Messages app.  Sorry if I misunderstood.

@MSohm you understood me correctly - I wanted to take advantage of everything the default mail app offers and your first reply was what I needed as information.
I wanted to avoid creating custom forms for email sending.
I ended up using @omar123456789 approach though and it seems to work well.
