Can't Receive Mail From Gmail

May 17, 2024 Post a Comment

I have been trying to receive mail from a gmail account. But I could not do that. I read all questions in Stack Overflow and tried all answers but it didn't work. Yesterday I found

Solution 1:

You didn't say whether you had found the code on the JavaMail FAQ. There's a lot of old and bad code floating around out there on the internet but the code on the FAQ is known to work. Still, it sounds like you've got code that works on the console so maybe this is an Android specific problem. It's always hard to know what could be going wrong there since Android isn't Java. The JavaMail FAQ also has debugging tips, in case you haven't found them. In particular, a protocol trace might provide the information necessary for others to help you debug the problem.

Solution 2:

StringSSL_FACTORY="javax.net.ssl.SSLSocketFactory";
Propertiespr=newProperties();
pr.setProperty("mail.pop3.socketFactory.class", SSL_FACTORY);
pr.setProperty("mail.pop3.socketFactory.fallback", "false");
pr.setProperty("mail.pop3.port",  "995");
pr.setProperty("mail.pop3.socketFactory.port", "995");
pr.put("mail.pop3.host", "pop.gmail.com");
pr.setProperty("mail.store.protocol", "pop3");

            try {
                Sessionsession= Session.getDefaultInstance(pr, null);
                Storestore= session.getStore();
                store.connect("username", "password");
                if(store.isConnected()==true)
                {
                System.out.println("Connection is OK");
                }
//              Folder inbox = store.getFolder("INBOX");Folderinbox= store.getDefaultFolder().getFolder("INBOX");
                inbox.open(Folder.READ_ONLY);
                Message messages[] = inbox.getMessages();
                for(Message message:messages) 
                {
//              System.out.println(message.getSentDate());
                message.writeTo(System.out);
                }

With this code, I can only move to "store.connect" line. On this line, application stop unexpectedly. So, I couldnt connect even. Using with mail.jar on Eclipse,Android Project

Solution 3:

I had problems reading some gmail messages, so I asked a question regarding that here. The code in the question can be a good working example for you.

And yes, you can read mails from any server that supports pop3 or imap access. Example for hotmail, just change the host to pop3.live.com and protocol to pop3s. Hope that helps!!

Solution 4:

try this one code

Mail m = new Mail(your email_id), your id password ));
String[] toArr = { send email id };
m.setTo(toArr);
m.setFrom(your email_id);
m.setSubject("Out of subject");
m.setBody("Out Of msg ");
try {
  m.send();
// Log.v("TAg", "send Mail");
} catch (Exception e) {
// Log.e("MailApp", "Could not send email", e);
}

You will also learn how to use the HTTP protocol to talk to web servers so that you can download text and binary data. The last part of this chapter shows you how to parse XML files to extract the relevant parts of an XML file — a technique that is useful if you are accessing Web services.
