Android: Send e-mail with attachment automatically in the background [duplicate]

Below is a complete class that supports sending emails with attachments in Android

And here is a utility function to send mail with attachment where the attachment in your case is simply the picture(s) file complete path

public static boolean sendEmail(String to, String from, String subject,                                                                         String message,String[] attachements) throws Exception {         Mail mail = new Mail();    if (subject != null && subject.length() > 0) {        mail.setSubject(subject);    } else {        mail.setSubject("Subject");    }    if (message != null && message.length() > 0) {        mail.setBody(message);    } else {        mail.setBody("Message");    }    mail.setTo(new String[] {to});    if (attachements != null) {        for (String attachement : attachements) {                   mail.addAttachment(attachement);        }    }    return mail.send();}

Here is the complete Mail class that is used in the above function

Note:

• You will need activiation.jar and mail.jar in your classpath i.e. JavaMail API
• The code should run from AsynchTask or dedicated Thread

Assuming your device of emualtor has a email application, the below code can be used to sent a mail. You can use any email application installed on your emualtor or device be it yahoomail or google. If you want tp run the same in background use a service.

Intent i = new Intent(Intent.ACTION_SEND);  //i.setType("text/plain"); //use this line for testing in the emulator  i.setType("message/rfc822") ; // use from live devicei.setClassName("com.google.android.gm", "com.google.android.gm.ComposeActivityGmail");//sending email via gmaili.putExtra(Intent.EXTRA_EMAIL, new String[]{"test@gmail.com"});  i.putExtra(Intent.EXTRA_SUBJECT,"subject goes here");  i.putExtra(Intent.EXTRA_TEXT,"body goes here");  startActivity(i);
