安卓端离线在上线后，接收不到 openfire推送的消息怎么解决，顺便问一下openfire 广播发送消息是不能发送离线消息吗

Answer 1

当然可以啦，离线要用OfflineMessageManager。

XMPPConnection con = ...;
OfflineMessageManager offlineManager = new OfflineMessageManager(con);
Iterator<org.jivesoftware.smack.packet.Message> it = offlineManager.getMessages();
Map<String, ArrayList<Message>> offlineMsgs = new HashMap<String, ArrayList<Message>>();

while (it.hasNext()) {
org.jivesoftware.smack.packet.Message message = it.next();

...
}
