我遇到了与两个用于套接字编程的仿真器有关的问题...我为该服务器端和其他客户端创建了两个应用程序
服务器端
server.java
package com.server.example;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.widget.Toast;
import java.net.DatagramPacket;
import java.net.DatagramSocket;
import java.net.InetAddress;
public class Server implements Runnable
{
private String address ="10.0.2.15";
private String add="10.0.2.2";
Context context;
@Override
public void run()
{
try{
InetAddress serveradd = InetAddress.getByName(address);
InetAddress clientadd = InetAddress.getByName(add);
DatagramSocket socket=new DatagramSocket(6000,serveradd);
byte[] buf = new byte[5];
byte[] bufsend =("hi").getBytes();
DatagramPacket packet=new DatagramPacket(buf,buf.length);
socket.receive(packet);
Toast.makeText(context.getApplicationContext(),"received"+new String(packet.getData()),Toast.LENGTH_LONG).show();
DatagramPacket packetsend=new DatagramPacket(bufsend,bufsend.length,clientadd,5000);
socket.send(packetsend);
}
catch (Exception e)
{
//Toast.makeText(context.getApplicationContext(),"received"+e,Toast.LENGTH_LONG).show();
}
}
}
serverActivity.java
package com.server.example;
import android.app.Activity;
import android.os.Bundle;
public class ServerActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
new Thread(new Server()).start();
}
}
client.java
package com.client1.example;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.widget.Toast;
import java.net.DatagramPacket;
import java.net.DatagramSocket;
import java.net.InetAddress;
public class Client implements Runnable
{
private String address ="10.0.2.15";
private String add="10.0.2.2";
Context context;
@Override
public void run()
{
try{
InetAddress serveradd = InetAddress.getByName(address);
InetAddress clientadd = InetAddress.getByName(add);
DatagramSocket socket=new DatagramSocket(5000,clientadd);
byte[] buf = new byte[5];
byte[] bufsend =("hello").getBytes();
DatagramPacket packetsend=new DatagramPacket(bufsend,bufsend.length,serveradd,6000);
DatagramPacket packet=new DatagramPacket(buf,buf.length);
socket.send(packetsend);
Toast.makeText(context.getApplicationContext(),"received"+new String(packet.getData()),Toast.LENGTH_LONG).show();
socket.receive(packet);
}
catch (Exception e)
{
//Toast.makeText(context.getApplicationContext(),"received"+e,Toast.LENGTH_LONG).show();
}
}
}
clientActivity.java
package com.client1.example;
import android.app.Activity;
import android.os.Bundle;
public class Client1Activity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
new Thread(new Client()).start();
}
}

服务器活动正在模拟器5554上运行，我已使用
重定向它redir add udp:5000:6000
我添加了互联网权限...程序运行没有错误，但启动时没有任何反应
任何类型的帮助将不胜感激
谢谢
