標題: Android Client和Server連接
本帖最後由 caonipig 於 2014-10-1 18:53 編輯

目前開發一個專案是將Client端的留言傳到Android Server上的SQLite儲存
想請問一下大家 Client和Server設定在同一個Port照理說不就會連到嗎?
Log顯示出Client在InetAddress後就跳到IO例外了要怎麼解決呢?
以下是程式碼:
package ccc.ClientSocketDemo3;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.net.InetAddress;
import java.net.Socket;
import java.net.UnknownHostException;
import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
public class ClientSocketDemo3 extends Activity {
public static Handler mHandler = new Handler();
TextView TextView01; // 用來顯示文字訊息
EditText EditText01; // 文字方塊
EditText EditText02; // 文字方塊
String tmp; // 暫存文字訊息
//Socket clientSocket; // 客戶端socket
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView01 = (TextView) findViewById(R.id.TextView01);
EditText01=(EditText) findViewById(R.id.EditText01);
EditText02=(EditText) findViewById(R.id.EditText02);
/*Thread t = new Thread(readData);
t.start();*/
Button button1=(Button) findViewById(R.id.Button01);

button1.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
try {
InetAddress addr =InetAddress.getByName("192.168.0.12");
Socket soc = new Socket(addr, 91);
Toast.makeText(ClientSocketDemo3.this, "輸入成功", Toast.LENGTH_LONG).show();
OutputStream oos = soc.getOutputStream();
BufferedWriter bw;
try {
bw = new BufferedWriter( new OutputStreamWriter(oos));
bw.write(EditText01.getText()+"$"+EditText02.getText()+"
");
bw.flush();
} catch (IOException e) {
}
EditText02.setText("");
//}
} catch (UnknownHostException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

});

}
private Runnable updateText = new Runnable() {
public void run() {
TextView01.append(tmp + "
");
}
};
/*private Runnable readData = new Runnable() {
public void run() {
//InetAddress serverIp;
try {
//serverIp = InetAddress.getByName("10.0.2.2");
//int serverPort = 5050;
//clientSocket = new Socket(serverIp, serverPort);
BufferedReader br = new BufferedReader(new InputStreamReader(
clientSocket.getInputStream()));
while (clientSocket.isConnected()) {
tmp = br.readLine();
if(tmp!=null)
mHandler.post(updateText);
}
} catch (IOException e) {
}
}
};*/

1.網路部分請使用thread來處理。
2.貼 log 來看看。

1.我是用Thread來撰寫Server的部分
package com.example.androidserversocket;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.ArrayList;
import java.util.Calendar;
import java.util.HashMap;
import java.util.StringTokenizer;

import android.app.Activity;
import android.content.ContentValues;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.util.Log;
import android.widget.ListView;
import android.widget.TextView;

public class MainActivity extends Activity {
TextView info, infoip, msg;
String message = "";
ServerSocket serverSocket;
DBConnection connect;
SQLiteDatabase db;
ArrayList<HashMap<String, String>> listvalues;
ListView listview;
private int mYear;
private int mMonth;
private int mDay;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
info = (TextView) findViewById(R.id.info);
connect=new DBConnection(MainActivity.this);
Calendar c=Calendar.getInstance();//建立抓日期物件c
      mYear=c.get(Calendar.YEAR);//年
      mMonth=c.get(Calendar.MONTH);//月
      mDay=c.get(Calendar.DAY_OF_MONTH);//日
      listvalues = new ArrayList<HashMap<String,String>>();
listview = (ListView)findViewById(R.id.listview);
/*infoip = (TextView) findViewById(R.id.infoip);
msg = (TextView) findViewById(R.id.msg);
infoip.setText(getText());*/
Thread socketServerThread = new Thread(new SocketServerThread());
socketServerThread.start();

}
@Override
protected void onDestroy() {
super.onDestroy();
if (serverSocket != null) {
try {
serverSocket.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

//Server由Thread開始執行
private class SocketServerThread extends Thread{
public void run() {

ServerSocket listener;
try {
listener = new ServerSocket(91);
Log.v("tag","messageserver1");
            while (true) {
                  Socket socket = listener.accept();
                  Log.v("tag","messageserver2");
                  try {
                    InputStream is = socket.getInputStream();
                    BufferedReader br = new BufferedReader(new InputStreamReader(is));
                    String str = br.readLine();
                    StringTokenizer st = new StringTokenizer(str, "$");
                    String username = st.nextToken();
                    String detail = st.nextToken();
                    String by = st.nextToken();
                    String date =st.nextToken();
                    ContentValues values = new ContentValues();
                    values.put("username", username.toString());
        values.put("detail", detail.toString());
        values.put("by", by.toString());
        values.put("date",date);
        db.insert("contact", null, values);
        db.close();

                    }finally{
                  socket.close();
                    }
   }
      }catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
   }

}

2.Log的部分
10-02 14:42:38.490: D/ExchangeService(685): Received deviceId from Email app: null
10-02 14:42:38.490: D/ExchangeService(685): !!! deviceId unknown; stopping self and retrying
10-02 14:42:43.510: D/ExchangeService(685): !!! EAS ExchangeService, onCreate
10-02 14:42:43.520: D/ExchangeService(685): !!! EAS ExchangeService, onStartCommand, startingUp = false, running = false
10-02 14:42:43.532: D/ExchangeService(685): !!! EAS ExchangeService, onStartCommand, startingUp = true, running = false
在跑完InetAddress下的message1之後直接跳到下面IO例外的message5,顯示了上面這些

1.我有說網路只有 server 端才需要用 thread 處理嗎？
2.server 端的 port 沒記錯的話在 1024 以下好像不能用。
3.log 看起來不像是當機時的 log。

好軟体是一定要支持的謝謝
