Java Mail Exception in Android

Question

I am facing a strange problem. I am connecting the gmail server through IMAP. It is connecting fine at the first attempt fine. But when I connecting the store for the second time, I am getting exception. Please help. Below is the code which I have used.

String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";
        try {

            Properties properties = new Properties();
            properties.setProperty("mail.store.protocol", "imaps");
    //      properties.setProperty("mail.imaps.socketFactory.fallback", "false");


            // set this session up to use SSL for IMAP connections
            properties.setProperty("mail.imap.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
            properties.setProperty("mail.imaps.socketFactory.fallback", "false");

            // use the simap port for imap/ssl connections.
        //  properties.setProperty("mail.imap.socketFactory.port", "993");

            URLName url = new URLName("imap", _INCOMINGMAILSERVER, 993, "", _USERNAME, _PASSWORD);

            Session session = Session.getInstance(properties,null);
            session.setDebug(true);

            //Store store = session.getStore("imaps");
            Store store = new IMAPSSLStore(session, url);


            if (store.isConnected()) {
                Log.v("Connected", "TRUE");
            } else {
                Log.v("Connected", "FALSE");
                /*
                 * store.connect(_OUTGOINGMAILSERVER, _USERNAME, _PASSWORD); if
                 * (store.isConnected()) store.close();
                 */


                Log.v("INCOMING SERVER", _INCOMINGMAILSERVER);
                //store.connect(_INCOMINGMAILSERVER, _USERNAME, _PASSWORD);
                store.connect();
            }
            connected = true;

OK NOW I AM USING THIS:-

Properties properties = new Properties();
properties.setProperty("mail.store.protocol", "imaps");
Session session = Session.getInstance(properties,null);
session.setDebug(true);
Store store = session.getStore("imaps"); 
store.connect(_INCOMINGMAILSERVER, _USERNAME, _PASSWORD);

Also I close the store after getting message stuffs.

But still the same error while connecting for the second time. It seems the server is not responding or the port is somewhat busy while connecting second time. I can't figure it out.

Clean up your code by getting rid of all that socket factory stuff, and follow the procedure here for connecting to Gmail. Be sure to use Session.getStore instead of instantiating the IMAPSSLStore yourself.
