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**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 12345int 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：
