三型布局的网站,做网站要求什么条件,网络应用服务管理,团员注册网站我正在编写一个代码#xff0c;需要每秒从Android移动设备向台式计算机(linux服务器)发送数据。由于数据经常发送#xff0c;通过Http命中无法实现(因为会消耗时间)#xff0c;所以Tcp通信似乎是更好的选择#xff0c;因为android手机的数据可以通过此套接字编程快速发送。…我正在编写一个代码需要每秒从Android移动设备向台式计算机(linux服务器)发送数据。由于数据经常发送通过Http命中无法实现(因为会消耗时间)所以Tcp通信似乎是更好的选择因为android手机的数据可以通过此套接字编程快速发送。 客户端的Android手机上的代码是Android和Linux服务器之间的TCP连接import java.io.IOException;import java.io.OutputStream;import java.io.PrintWriter;import java.net.InetAddress;import java.net.Socket;import java.net.UnknownHostException;import android.app.Activity;import android.os.Bundle;import android.util.Log;import android.view.View;import android.widget.Button;import android.widget.EditText;import android.widget.TextView;public class GetWebPage extends Activity {//Handler h;public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);final EditText eText (EditText) findViewById(R.id.address);final TextView tView (TextView) findViewById(R.id.pagetext);final Button button (Button) findViewById(R.id.ButtonGo);button.setOnClickListener(new Button.OnClickListener() {public void onClick(View v) {try {Log.v(Tcp,Clicked the button);InetAddress serveraddressInetAddress.getByName(67.23.14.156);Log.v(Tcp, Got the InetAddress);Socket s new Socket(serveraddress,4447);Log.v(Tcp,Got the Socket address);OutputStream out s.getOutputStream();PrintWriter output new PrintWriter(out);output.println(Hello Android!);out.close();} catch (UnknownHostException e) {tView.setText(e.toString());Log.v(Tcp,e.toString());} catch (IOException e) {tView.setText(e.toString());Log.v(Tcp,e.toString());}catch (Exception e) {tView.setText(e.toString());}}});}}服务器端代码import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;import java.net.ServerSocket;import java.net.Socket;public class ListenIncomingTcpConnection {public static void main(String[] args) {ServerSocket serverSocketnull;Socket clientnull;try {System.out.println(Creating the server object...);serverSocket new ServerSocket(4447);System.out.println(Waiting for the connection...);} catch (IOException e1) {System.out.println(e1);}while (true) {try {client serverSocket.accept();System.out.println(Reading the content...);} catch (IOException e1) {System.out.println(e1);e1.printStackTrace();}try {BufferedReader in new BufferedReader(new InputStreamReader(client.getInputStream()));String str in.readLine();System.out.println(Reading the content.....);} catch(Exception e) {System.out.println(e);} finally {try{client.close();}catch(Exception e){System.out.println(e);}}}//while}//PSVM}清单文件的代码是packagecom.spce android:versionCode1 android:versionName1.0我已经执行了服务器端的代码在linux机器上通过putty上的“java”命令。它在此行执行并停止“client serverSocket.accept();” 当我执行的Android手机客户端它说单击该按钮 得到InetAddress是否 java.net.SocketException异常没有到主机的路由我不能够发现的这种情况的原因没有路由到主机。请帮忙解决问题。2011-03-15Khushboo
