android - 使用 Smack Api for Android 发送和接收消息

Question

自从过去四天以来，我一直在尝试使用自己的 XMPP 和 Smack+OpenFire 发送和接收聊天消息。根据 Smack 的“readme.txt”，我设置了连接并让用户登录。连接和登录的代码是这样的

public static String TAG = "Test connection";
private static XMPPTCPConnection connection;
private static String userName = "demo";
private static String Password = "demo";

static {
    // Create the configuration for this new connection
    XMPPTCPConnectionConfiguration.Builder configBuilder = XMPPTCPConnectionConfiguration.builder();
    configBuilder.setSecurityMode(XMPPTCPConnectionConfiguration.SecurityMode.disabled);
    configBuilder.setResource("");
    configBuilder.setUsernameAndPassword(userName, Password);
    configBuilder.setServiceName("192.168.2.10");
    configBuilder.setHost("192.168.2.10");
    configBuilder.setPort(5222);
    configBuilder.setCompressionEnabled(false);
    connection = new XMPPTCPConnection(configBuilder.build());
}

这样我就配置了 connectionbuilder。我在这里连接并登录用户。

public class ConnectAndLogin extends AsyncTask<Void, Void, Void> {
    @Override
    protected Void doInBackground(Void... params) {
        try {
            connection.connect();
            Log.i(TAG, "Connected to " + connection.getHost());
        } catch (SmackException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (XMPPException e) {
            Log.e(TAG, "Failed to connect to " + connection.getHost());
            Log.e(TAG, e.toString());
            e.printStackTrace();
        }

        try {
            connection.login(userName, Password);
            Log.i(TAG, "Login as a : " + connection.getUser());
            setConnection(connection);
            setListner();
        } catch (XMPPException e) {
            e.printStackTrace();
            Log.i(TAG, "Login error " + e.toString());
        } catch (SmackException e) {
            e.printStackTrace();
            Log.i(TAG, "Login error " + e.toString());
        } catch (IOException e) {
            e.printStackTrace();
            Log.i(TAG, "Login error " + e.toString());
        }


        return null;
    }
}

在某些教程中，必须在登录后设置addPacketListner。我在 setConnection() 中完成了此操作，一些帖子通过了 addAsyncStanzaListner。用于发送消息

send.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Message msg = new Message("demo2", Message.Type.chat);
            msg.setBody("Hi how are you");
            if (connection != null) {
                try {
                    connection.sendPacket(msg);
                    Log.d("Send to room  : Name : ", "demo2");
                    Log.d("store", "store data to db");
                    //DBAdapter.addUserData(new UserData(text, "", "1" ,beam_id));
                } catch (Exception e) {
                    Log.d("ooo", "msg exception" + e.getMessage());
                }
            }
        }
    });

以及用于接收消息此代码

 public void setListner() {
    connection.addAsyncStanzaListener(new StanzaListener() {
        @Override
        public void processPacket(Stanza packet) throws SmackException.NotConnectedException {
            Message message = (Message) packet;
            Log.i(TAG, "REC : " + message.getBody());
            Log.i(TAG, "REC: " + message.getFrom());


        }

    }, new StanzaFilter() {
        @Override
        public boolean accept(Stanza stanza) {
            return false;
        }
    });
}

这是我的依赖

 compile 'org.igniterealtime.smack:smack-android:4.1.0'
compile 'org.igniterealtime.smack:smack-tcp:4.1.0'
compile 'org.igniterealtime.smack:smack-core:4.1.0'
compile 'org.igniterealtime.smack:smack-im:4.1.0'
compile 'org.igniterealtime.smack:smack-resolver-minidns:4.1.0'
compile 'org.igniterealtime.smack:smack-sasl-provided:4.1.0'

但我仍然无法向 demo2 用户发送消息。我哪里做错了。请指导和帮助我。谢谢
