Question

嘿，我使用openfire servr和android Smack进行聊天时遇到了一些问题我的日志猫有一些错误。我只是wanaa连接的简单代码我不知道我的代码中有什么问题.. 这是我的代码：

package com.exm.dor;

    m_handler = new Handler();
    try {

}


private void initConnection() throws XMPPException {

    ConnectionConfiguration config =

    m_connection = new XMPPConnection(config);
    m_connection.connect();
    m_connection.login(LOGIN, PASSWORD);
    Presence presence = new Presence(Presence.Type.available);
    m_connection.sendPacket(presence);

    //enregistrement de l'יcouteur de messages
    PacketFilter filter = new MessageTypeFilter(Message.Type.chat);
    m_connection.addPacketListener(new PacketListener() {
            public void processPacket(Packet packet) {
                Message message = (Message) packet;
                if (message.getBody() != null) {
                    String fromName = StringUtils.parseBareAddress(message
                            .getFrom());
                    m_discussionThread.add(fromName + ":");
                    m_discussionThread.add(message.getBody());

                    m_handler.post(new Runnable() {
                        public void run() {
                            m_discussionThreadAdapter.notifyDataSetChanged();
                        }
                    });
                }
            }
        }, filter);
}

}

这是logcat：

请尝试这种方式，希望这有助于您解决问题。

使用AsyncTask，使您的网络呼叫在不同的线程（在后台）而不是在应用程序的主线程上。

public class MainActivity extends Activity {
    private final static String SERVER_HOST = "10.0.2.2";
    private final static int SERVER_PORT = 5222;
    private final static String SERVICE_NAME = "search.drcode";
    private final static String LOGIN = "dorperezz";
    private final static String PASSWORD = "123123";


    private List<String> m_discussionThread;
    private ArrayAdapter<String> m_discussionThreadAdapter;
    private XMPPConnection m_connection;
    private EditText recipient;
    private EditText message;
    private ListView list;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        recipient = (EditText) this.findViewById(R.id.recipient);
        message = (EditText) this.findViewById(R.id.message);
        list = (ListView) this.findViewById(R.id.thread);


        new ConnectToXmpp().execute();
        Button send = (Button) this.findViewById(R.id.send);
        send.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                String to = recipient.getText().toString();
                String text = message.getText().toString();

                Message msg = new Message(to, Message.Type.chat);
                msg.setBody(text);
                m_connection.sendPacket(msg);
                m_discussionThread.add("moi :");
                m_discussionThread.add(text);
                m_discussionThreadAdapter.notifyDataSetChanged();
            }
        });
    }

    class ConnectToXmpp extends AsyncTask<Void, Void, Void> {

        @Override
        protected Void doInBackground(Void... params) {
            try {
                ConnectionConfiguration config = new ConnectionConfiguration(SERVER_HOST, SERVER_PORT, SERVICE_NAME);
                m_connection = new XMPPConnection(config);
                m_connection.connect();
                m_connection.login(LOGIN, PASSWORD);
                Presence presence = new Presence(Presence.Type.available);
                m_connection.sendPacket(presence);

                PacketFilter filter = new MessageTypeFilter(Message.Type.chat);
                m_connection.addPacketListener(new PacketListener() {
                    public void processPacket(Packet packet) {
                        Message message = (Message) packet;
                        if (message.getBody() != null) {
                            String fromName = StringUtils.parseBareAddress(message
                                    .getFrom());
                            m_discussionThread.add(fromName + ":");
                            m_discussionThread.add(message.getBody());
                            m_discussionThreadAdapter.notifyDataSetChanged();
                        }
                    }
                }, filter);
            } catch (XMPPException e) {
                e.printStackTrace();
            }

            return null;
        }

        @Override
        protected void onPostExecute(Void result) {
            m_discussionThread = new ArrayList<String>();
            m_discussionThreadAdapter = new ArrayAdapter<String>(this,R.layout.multi_line_list_item, m_discussionThread);
            list.setAdapter(m_discussionThreadAdapter);
        }

    }
}

Answer 2

Caused by: android.os.NetworkOnMainThreadException

这是你的问题。您正在主线程上连接套接字。尝试在其中创建一个连接套接字的全局服务。

此外，您可以为该内容提供重试策略。您还可以从github搜索执行整个任务的开源项目。您可以为项目添加所需的代码，以获得更可靠的方式，因为您的代码不会遇到生产挑战。

添加参考 https://github.com/siacs/Conversations

Answer 3

只需在setContentView（）后添加此行onCreate（）：

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();

StrictMode.setThreadPolicy(policy);

我认为这样可以解决你的问题
