you problem is this android.os.NetworkOnMainThreadException, use thread to run the code — raditya gumay, May 19 '16 at 02:55

Try this way,hope this will help you to solve your problem.

Use AsyncTask which makes your network call on different thread(in background) rather than on app's main thread.

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;

Caused by: android.os.NetworkOnMainThreadException

This is your problem. You are connecting socket on main thread. Try creating a global service an connect socket in that.

Also you can provide a retry policy for that thing. You can also search for open source project from github which do the whole task. You can add the required code for the projects for more reliable way coz your code will not stand production challenges.

Adding a reference https://github.com/siacs/Conversations

Jsut add this line onCreate() after setContentView() :

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

StrictMode.setThreadPolicy(policy);

I think so it will solve your problem
