我如何在smack openfire android中监听传入的订阅请求 [英] How can i listen incoming subscription request in smack openfire android

问题描述

我正在使用一击开火创建一个android聊天应用程序.我面临的问题是我知道如何发送和接受订阅请求，但是如何知道我是否收到任何订阅请求. 我使用了Stanza侦听器，但该侦听器仅侦听传入的聊天消息，而不侦听订阅请求. 下面是我的代码

I am creating an android chat application using a smack open fire. The problem that I am facing is I know how to send and accept subscription requests but how can I know if I have received any subscription request. I have used Stanza listener but the listener is only listening to incoming chat messages, not subscription requests. Below is my code

StanzaFilter filter=new StanzaTypeFilter(Message.class);
        PacketCollector collector=connection.createPacketCollector(filter);
        connection.addAsyncStanzaListener(new StanzaListener() {
            @Override
            public void processPacket(Stanza packet) throws SmackException.NotConnectedException {
                Log.wtf("MA","Stanz listner");
            }
        },filter);

我是初学者，请帮助我如何收听传入的订阅请求.预先感谢.

推荐答案

这是我在Android代码中所做的事情

This is how I have done in my android code

StanzaFilter subscribefilter = PresenceTypeFilter.SUBSCRIBE;
PresenceSubscribeListener subscribeListener = new PresenceSubscribeListener(context.getApplicationContext(), connection);
connection.addSyncStanzaListener(subscribeListener, subscribefilter);

然后，该连接对象已在Android的长期运行服务中被引用.这样做的目的是，当您的应用程序在后台接收数据包时，您仍然可以处理传入的状态数据包.

And then this connection object has been referenced in a long running service in Android. This has been done such that when a packet is received when you app is in background, you can still process the incoming presence packet.

P.S.我在Android代码中使用了smack 4.1.9.
