- by SikhWarrior
Im trying to create a simple mail client in android, and I have the android version of javamail compiling and running in my app.
However, whenever I try to connect and receive mail, I get a Folder Closed exception seen below.

My code is as follows:
public static Message[] getAllMail(String user, String pwd){
String host = "imap.sfu.ca";
final Message[] NO_MESSAGES = {};
Properties properties = System.getProperties();
properties.setProperty("mail.imap.socketFactory.class",
"javax.net.ssl.SSLSocketFactory");
properties.setProperty("mail.imap.socketFactory.port", "993");
Session session = Session.getDefaultInstance(properties);
try {
Store store = session.getStore("imap");
store.connect(host, user, pwd);
Folder folder = store.getFolder("inbox");
folder.open(Folder.READ_ONLY);
Message[] messages = folder.getMessages();
folder.close(true);
store.close();
Log.d("####TEAM ZETA DEBUG####", "Content: " + messages.length);
return messages;
} catch (NoSuchProviderException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (MessagingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Log.d("####TEAM ZETA DEBUG####", "Returning NO_MESSAGES");
return NO_MESSAGES;
}
public static String getMessageHTML(Message message){
Object msgContent;
try {
msgContent = message.getContent();
if (msgContent instanceof Multipart) {
Multipart mp = (Multipart) msgContent;
for (int i = 0; i < mp.getCount(); i++) {
BodyPart bp = mp.getBodyPart(i);
if (Pattern
.compile(Pattern.quote("text/html"),
Pattern.CASE_INSENSITIVE)
.matcher(bp.getContentType()).find()) {
// found html part
return (String) bp.getContent();
} else {
// some other bodypart...
}
}
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (MessagingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return "Something went wrong";
}
I couldn't find anything helpful on the web, does anyone have an ideas why this is happening??
This is called in
class GetAsyncEmails extends AsyncTask<String, Integer, Message[]>{
@Override
protected Message[] doInBackground(String... args) {
// TODO Auto-generated method stub
Message[] messages = MailHelper.getAllMail(args[0], args[1]);
return messages;
}
protected void onPostExecute(Message[] result){
if(result.length > 1){
Message message = result[0];
String content = MailHelper.getMessageHTML(message);
System.out.println("####TEAM ZETA DEBUG####" + content);
}
}
}
