Question

我正在尝试使用openfire，smack和android的聊天应用程序，其中脱机消息不起作用。如果两个用户都在线，则能够正确地发送和接收消息。但是，如果用户A处于离线状态而用户B发送了一条消息，则用户A一旦在线就没有收到B的已发送消息。来自stackoverflow的可能解决方案但没有一个正常工作。使用以下代码检索脱机消息。

new Thread（）{ public void run（）{

from pyChrome import PyChrome
>>> link = "http://www.destinylfg.net/"
>>> from pyChrome import PyChrome
>>> browser = PyChrome()

经过多次斗争，我已经解决了这个问题。在您的openfire管理页面中，转到＆＃34;客户端设置＆＃34;并将空闲时间从360秒（默认情况下）减少到1秒（可能）。只有当您与Internet断开连接时，它才会检测到您处于脱机状态并将其余消息保留为OFFLINE。

@Override public void onNetworkConnectionChanged（boolean isConnected）{

if(isConnected){
    new Thread() {

        public void run() {
            try {
                XMPPTCPConnectionConfiguration.Builder builder = XMPPTCPConnectionConfiguration.builder();
                builder.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
                builder.setUsernameAndPassword("phone", "admin");
                builder.setSendPresence(true);
                builder.setServiceName(<Service name>);
                builder.setHost(<Host name>);
                builder.setResource("Test");
                builder.setDebuggerEnabled(true);
                Presence presence = new Presence(Presence.Type.available);
                presence.setStatus("Available");
                connection = new XMPPTCPConnection(builder.build());
                connection.connect();
                connection.login();
                Presence presence123 = new Presence(Presence.Type.available);
                presence123.setStatus("Available");
                try {
                    connection.sendStanza(presence123);
                } catch (SmackException.NotConnectedException e) {
                    e.printStackTrace();
                }
                StanzaFilter filter = new AndFilter(new StanzaTypeFilter(Message.class));
                PacketListener myListener = new PacketListener()
                {
                    public void processPacket(Stanza stanza)
                    {
                        retrieveMessage(stanza,userType);
                    }
                };
                connection.addPacketListener(myListener, filter);
                try {
                    connection.sendStanza(presence);
                } catch (SmackException.NotConnectedException e) {
                    e.printStackTrace();
                }

            } catch (SmackException | XMPPException | IOException e) {
                e.printStackTrace();
            }


            //return connection.isConnected();
        }

    }.start();

以上工作正常，能够检索离线消息。方法＆＃34; retrieveMessage（节，用户类型）;＆＃34;用于处理传入的消息并更新适配器。确保将状态发送为＆＃34;可用＆＃34;当你重新连接。如果还有任何问题，请告诉我。

没有得到smack的离线消息
