我试图编写一个程序，使用具有android手机作为客户端和我的电脑作为服务器我发现和稍微修改代码双方和我的服务器代码工作，但我可以' t得到客户的活动，我不知道如何得到的程序谈话我想基本上能够有任何一方输入文本，并已发送和设置可见其他我知道有多少坚持你们有问题，所以...我如何获得这些沟通？服务器/客户端Android到PC通信问题
客户端代码（仿真器崩溃之前，我甚至可以开始看到这个问题）
package com.example.Socket;
import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.util.Log;
import android.view.View;
import android.view.View.*;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import java.io.*;
import java.net.*;
public class ClientActivity extends Activity {
private EditText serverIp;
private Button connectPhones;
private String serverIpAddress = "";
private boolean connected = false;
private Handler handler = new Handler();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.client);
serverIp = (EditText) findViewById(R.id.server_ip);
connectPhones = (Button) findViewById(R.id.connect_phones);
connectPhones.setOnClickListener((android.view.View.OnClickListener) connectListener);
}
private OnClickListener connectListener = new OnClickListener() {
@Override
public void onClick(View v) {
if (!connected) {
serverIpAddress = serverIp.getText().toString();
if (!serverIpAddress.equals("")) {
Thread cThread = new Thread(new ClientThread());
cThread.start();
}
}
}
};
public class ClientThread implements Runnable {
public void run() {
try {
InetAddress serverAddr = InetAddress.getByName(serverIpAddress);
Log.d("ClientActivity", "C: Connecting...");
Socket socket = new Socket(serverAddr, 9999);
connected = true;
while (connected) {
try {
Log.d("ClientActivity", "C: Sending command.");
PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket
.getOutputStream())), true);
// where you issue the commands
out.println("Hey Server!");
Log.d("ClientActivity", "C: Sent.");
} catch (Exception e) {
Log.e("ClientActivity", "S: Error", e);
}
}
socket.close();
Log.d("ClientActivity", "C: Closed.");
} catch (Exception e) {
Log.e("ClientActivity", "C: Error", e);
connected = false;
}
}
}
}
服务器代码
import java.io.*;
import java.net.*;
/**

*/
public class Server {
/**
* @param args
*/
public static void main(String[] args) {
try {
// First we create a server socket and bind it to port 9999.
ServerSocket myServerSocket = new ServerSocket(9999);
// wait for an incoming connection...
System.out.println("Server is waiting for an incoming connection on host="
+ InetAddress.getLocalHost().getCanonicalHostName()
+ " port=" + myServerSocket.getLocalPort());
Socket skt = myServerSocket.accept();
// ok, got a connection. Let's use java.io.* niceties to read and write from the connection.
BufferedReader myInput = new BufferedReader(new InputStreamReader(skt.getInputStream()));
PrintStream myOutput = new PrintStream(skt.getOutputStream());
// attempt to read input from the stream.
String buf = myInput.readLine();
// if we got input, print it out and write a message back to the remote client..
if (buf != null) {
System.out.println("Server read: [" + buf + "]");
myOutput.print("got it");
}
// close the connection.
skt.close();
System.out.println("Server is exiting");
} catch (IOException ex) {
ex.printStackTrace();
System.out.println("Whoops, something bad happened! I'm outta here.");
}
}

它什么时候崩溃？当你尝试连接时它会崩溃吗？或活动何时启动？ – Jbecwar
它说程序被迫关闭错误是从模拟器不是蚀，它似乎是一个运行时错误 –
