android登陆socket通讯
写了一个登陆界面，输入账号密码点登陆之后连接服务器，在这里点了登陆之后，在Logcat里面输出的只有这个Log.i("log","123");，在之后的s = new Socket("10.82.11.218",8025);运行完这段话输出Log.i("log","1234");，可是就是这个连接不上，不知道哪里出现问题了。上网找了很多还是找不出，没有办法只好来求救。。。。MainActivity代码

Serversocket代码：
package com.zwm.net;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.ServerSocket;
import java.net.Socket;
public class Serversocket implements Runnable{
@Override
public void run() {
try {
ServerSocket ss = new ServerSocket(8025);
System.out.println("等待链接");
while(true){
Socket s = ss.accept();
System.out.println("链接了一次");
BufferedReader br = new BufferedReader(new InputStreamReader(s.getInputStream()));
String username = br.readLine();
String password = br.readLine();
if(username=="zwm"&&password=="888888"){
OutputStreamWriter os = new OutputStreamWriter(s.getOutputStream());
os.write("1");
}
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static void main(String args[]){
Serversocket c = new Serversocket();
new Thread(c).start();
}
}
