android 客户端连接c服务器_Android

在Android客户端连接C服务器时，可以使用Socket进行通信，以下是详细的步骤和代码示例：

1、创建C服务器

我们需要创建一个C服务器来监听客户端的连接请求，以下是一个简单的C服务器示例：

#include <
    stdio.h>
    
#include <
    stdlib.h>
    
#include <
    string.h>
    
#include <
    unistd.h>
    
#include <
    arpa/inet.h>
    
#include <
    sys/socket.h>

#define BUF_SIZE 1024
#define PORT 12345
int main() {
    
    int server_sock, client_sock;
    
    struct sockaddr_in server_addr, client_addr;
    
    socklen_t client_addr_size;
    
    char buffer[BUF_SIZE];
    
    server_sock = socket(PF_INET, SOCK_STREAM, 0);

    if (server_sock == 1) {
    
        perror("socket");
    
        exit(1);

    }
    
    memset(&
    server_addr, 0, sizeof(server_addr));
    
    server_addr.sin_family = AF_INET;
    
    server_addr.sin_addr.s_addr = htonl(INADDR_ANY);
    
    server_addr.sin_port = htons(PORT);
    
    if (bind(server_sock, (struct sockaddr *)&
server_addr, sizeof(server_addr)) == 1) {
    
        perror("bind");
    
        exit(1);

    }

    if (listen(server_sock, 5) == 1) {
    
        perror("listen");
    
        exit(1);

    }
    
    client_addr_size = sizeof(client_addr);
    
    client_sock = accept(server_sock, (struct sockaddr *)&
    client_addr, &
    client_addr_size);

    if (client_sock == 1) {
    
        perror("accept");
    
        exit(1);

    }

    while (1) {
    
        memset(buffer, 0, BUF_SIZE);
    
        int str_len = read(client_sock, buffer, BUF_SIZE 1);

        if (str_len == 1) {
    
            perror("read");
    
            break;

        }
 else if (strncmp(buffer, "exit", 4) == 0) {
    
            break;

        }
 else {
    
            write(client_sock, buffer, str_len);

        }

    }
    
    close(client_sock);
    
    close(server_sock);
    
    return 0;

}
    

2、Android客户端连接C服务器

我们在Android客户端中创建一个Socket来连接C服务器，以下是一个简单的Android客户端示例：

import java.io.BufferedReader;
    
import java.io.IOException;
    
import java.io.InputStreamReader;
    
import java.io.PrintWriter;
    
import java.net.Socket;
    
import android.os.Bundle;
    
import android.app.Activity;
    
import android.view.View;
    
import android.widget.Button;
    
import android.widget.EditText;
    
import android.widget.TextView;
    
import android.widget.Toast;
    
import android.util.Log;
    
import java.net.InetAddress;
    
import java.net.UnknownHostException;
    
import java.util.Arrays;
    
import java.util.List;
    
import java.util.Locale;
    
import java.util.regex.Pattern;
    
import java.util.regex.Matcher;
    
import java.util.ArrayList;
    
import java.util.Collections;
    
import java.util.Comparator;
    
import java.util.HashMap;
    
import java.util.Map;
    
import java.util.Set;
    
import java.util.HashSet;
    
import java.util.Iterator;
    
import java.util.Map.Entry;
    
import org.json.*;
