Question

我正在尝试生成一个简单的服务器，它允许我测试Androids的安全功能。我需要开发一个可以打开套接字的应用程序。我在C中制作了类似的东西，但我对java没有看法。这是C

中的应用程序

// simpleserver3.c


#define MY_PORT     9999
#define MAXBUF      99


void indata(int clientfd, struct sockaddr_in client_addr)
{
char buffer[12];
printf("%s:%d connected\n", inet_ntoa(client_addr.sin_addr), ntohs(client_addr.sin_port));
recv(clientfd, buffer, MAXBUF, 0); //this is will overflow the buffer
printf("%X \n", &buffer);
}

int main(int Count, char *Strings[])
{
struct sockaddr_in self, client_addr;
int sockfd,clientfd;
/*---Create streaming socket---*/
if ( (sockfd = socket(AF_INET, SOCK_STREAM, 0)) < 0 ) //socketfd = handle for socket
{
    perror("Socket");
    exit(errno);
}

/*---Initialize address/port structure---*/
bzero(&self, sizeof(self));
self.sin_family = AF_INET;
self.sin_port = htons(MY_PORT);
self.sin_addr.s_addr = INADDR_ANY;

/*---Bind the structure to the socket handle ---*/
if ( bind(sockfd, (struct sockaddr*)&self, sizeof(self)) != 0 )
{
    perror("socket--bind");
    exit(errno);
}

/*---Make it a "listening socket"---*/
if ( listen(sockfd, 20) != 0 )
{
    perror("socket--listen");
    exit(errno);
}

//set socklen_t to length of client address
socklen_t addrlen=sizeof(client_addr);
/*---accept a connection (creating a data pipe)---*/

clientfd = accept(sockfd, (struct sockaddr*)&client_addr, &addrlen); //create handle for communicating
indata(clientfd, client_addr);
close(clientfd);
close(sockfd);
return;
}

任何建议都会很棒，Aneel

我使用C已经有一段时间了，所以我无法对你的C代码发表评论，但你应该看一下Socket类的Android文档：
