http://blog.jayway.com/2008/11/21/give-back-my-xmpp-in-android/

SASL 관련 XMPPConnection클래스의 버그를 수정한 패치가 올려져 있다.

아래와 같은 에러 발생시 이 패치가 유용할 것이다.

Android – Just Use Smack API For XMPP

Filed under: Uncategorized — Davanum Srinivas @ 9:36 am

OUTDATED SAMPLE – Updated code is here:

http://davanum.wordpress.com/2008/12/29/updated-xmpp-client-for-android/

Using Smack XMPP API From Android

Once you get tired of the limitations of android’s built-in IMProvider and the corresponding API – IXmppSession and IXmppService, try the sample below. Inside the source/binary zip (bottom of this article) you will find a smack.jar that works with android. To build the jar yourself, You can download the Smack 3.0.4 sources from here and apply the patch here.

Here Is A Screen Shot Of The XMPP Settings Dialog.

Notes

For GTalk, use “gtalk.google.com” as host with port 5222. The service name is “gmail.com”

Don’t add “@gmail.com” in the user name, just the id will do

XMPP opensource library SMACK #2 - Processing Incoming Packets

수신되는 패킷을 처리하는데 두가지 방식을 지원한다.

org.jivesoftware.smack.PacketCollector -- 새로운 패킷이 올때까지 동기적으로 대기하는 클래스
org.jivesoftware.smack.PacketListener -- 수신되는 패킷을 비동기적으로 받는 인터페이스

패킷리스너는 이벤트스타일의 프로그래밍이다. 반면에 패킷콜렉터는 당신이 폴링으로 수집한 데이터를 큐잉하여 받게되며 그 동작은 블럭된다. 패킷리스너는 수신중에 언제든지 다른 작업이 가능하며 콜렉터는 원하는 패킷이 올때가지 대기할때 유용하다. 이 두가지는 모두 XMPPConnection의 인스턴스로부터 얻을수 있다.

org.jivesoftware.smack.filter.PacketFilter인터페이스는 패킷리스너와 패킷콜렉터가 전달받을킷을러주는 역할을 한다. org.jivesoftware.smack.filter패키지에 미리정의된 많은 사용가능한 필터들이 정의되어 있다.

아래 코드는 패킷리스너와 패킷콜렉터를 모두 사용하는 데모이다.

// Create a packet filter to listen for new messages from a particular

// user. We use an AndFilter to combine two other filters.
PacketFilter filter = new AndFilter(new PacketTypeFilter(Message.class), 
        new FromContainsFilter("mary@jivesoftware.com"));
// Assume we've created an XMPPConnection name "connection".

// First, register a packet collector using the filter we created.
PacketCollector myCollector = connection.createPacketCollector(filter);
// Normally, you'd do something with the collector, like wait for new packets.

// Next, create a packet listener. We use an anonymous inner class for brevity.
PacketListener myListener = new PacketListener() {
        public void processPacket(Packet packet) {
            // Do something with the incoming packet here.
        }
    };
// Register the listener.
connection.addPacketListener(myListener, filter);

Standard Packet Filters

아래는 Smack에서 제공하는 패킷필터들의 셋이다. PacketFilter인터페이스로 새로운 필터를 정의할수도 있다. 디폴트셋은 아래와 같다.

PacketTypeFilter -- 클래스타입을 지정할 수 있다.
PacketIDFilter -- 패킷 ID별로 지정할 수 있다.
ThreadFilter -- 메세지패킷의 스레드 ID별로 지정할 수 있다.
ToContainsFilter -- 받는 주소로 지정할 수 있다.
FromContainsFilter -- 보내는 주소로 지정할 수 있다.
PacketExtensionFilter -- 패킷의 확장부분을 지정할 수 있다.
AndFilter -- 논리적 AND 연산을 두개이상의 필터로 지정할 수 있도록 해준다.
OrFilter -- 논리적 OR 연산을 두개이상의 필터로 지정할 수 있도록 해준다.
NotFilter -- 논리적 NOT 연산을 두개이상의 필터로 지정할 수 있도록 해준다.

XMPP opensource library SMACK #1

Smack은 opensource로 제공되는 XMPP library이다. 안드로이드에서 사용이 가능하다.

실시간으로 XMPP server와 통신이 가능하고 인스탄트메세징과 채팅이 가능하다

아래와 같이 지극히 단순한 코드로 단문메세지를 전송할 수 있다.



XMPPConnection connection = new XMPPConnection("jabber.org");
connection.connect();
connection.login("mtucker", "password");
Chat chat = connection.getChatManager().createChat("jsmith@jivesoftware.com", new MessageListener() {

    public void processMessage(Chat chat, Message message) {
        System.out.println("Received message: " + message);
    }
});
chat.sendMessage("Howdy!"); 






프로그래머에게 패킷레벨의 접근이 필요없으며 Chat, Roater같은 상위레벨의 클래스를 사용하여 프로그래밍이 가능하다

XMPP XML format이나 XML에 대해서도 알필요가 없다.
