idel使用方法java,Javamail：为IMAPFolder发出idle（）的正确方法

I have set MessageCountListener for IMAPFolder. In order to get updates continuously I had to do the following, which is a killer for my app performance wise. It freezes the GUI since it's running for each and every folder.

while (true) {

try {

if (folder != null && folder.isOpen()) {

folder.idle();

} else {

getSyncListenersAttachedFolders().remove(syncFolder.getFolderID());

}

} catch (Exception ex) {

errorLOG.error("IDLE command issue exception.");

getSyncListenersAttachedFolders().remove(syncFolder.getFolderID());

}

}

Is there any better way of issuing idle command which will not run in a while(true) condition.

Expecting a quick response. Thanks in advance.

You need to run it in its own thread.
