We've corresponded (with each other) (ie written to each other) for years but I've never actually met him.
我们已（互相）通信多年了, 可是我从未见过他本人.
YourACCOUNTof events corresponds with hers.
你说的情况跟她说的相符.
Does the name on the envelope correspond with the name on the letter inside?
信封上的名字与里面信上的名字是否相同?

二 : android native socket correspond

最近在做android native socket通信。主要在native这里写socket服务端的程序。根据client需求，通过PC端串口发送AT command，native负责接受从PC端发送的命令，过滤有效命令，通过socket发送到APP端，APP收到命令后进行相关测试，之后将测试信息返回native，native发送到PC端串口，显示测试结果。
native的socket服务端的实现原理：创建后台服务，开启一个进程，监听串口消息。
流程如下：
1.在init.rc里增加服务
chown system system /dev/ttyGS0
chmod 0666 /dev/ttyGS0

on property:ro.baseband="unknown"
start at

service at /system/bin/at
socket sockettest stream 0666 radio system
user system
group system inet
disabled

2.native服务程序 /system/at/at.c
#if 1
#define LOG_TAG "AT"
#define SOCKET_NAME "sockettest"
#include <utils/Log.h>
#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
#include <string.h>

#define BUFSIZE 100
int count = 0;

#define LOGE(...) __android_log_print(ANDROID_LOG_ERROR, "myserver", __VA_ARGS__)

int main(){

#if 1
int connect_number = 4;
int fdListen = -1, new_fd = -1;
int fd, ret;
char ttyBuf[BUFSIZE];

char *msg = "";// "ttyGS0 test";
char *end = "rn";
struct sockaddr peeraddr;
socklen_t socklen = sizeof (peeraddr);
int numbytes ;
char buff[256];
fd_set fds;
int max = 0;
while(1){
fd = open("/dev/ttyGS0", O_RDWR);//打开usb serial device
//printf("envi serial test programn");
LOGD("envi serial test program","myserver");
if(fd < 0)
{
//printf("n");
LOGD("Error: open /dev/ttyGS0 error!","myserver");
return 1;
}

fdListen = android_get_control_socket(SOCKET_NAME);//创建native socket服务端本地连接
if (fdListen < 0) {
LOGD("Failed to get socket","myserver");
exit(-1);
}

LOGD("get","myserver");
ret = listen(fdListen, connect_number); //listen
if (ret < 0) {
LOGD("listen socket failed","myserver");
//perror("listen");
//exit(-1);
}
LOGD("geta","myserver");
//It block until client connected.accept(socket_id, &peeraddr, &socklen);
#if 1
new_fd = accept(fdListen, &peeraddr, &socklen); //与client端连接
if (new_fd < 0 ) {
//LOGD("Error on accept() errno:%d", errno);
LOGD("Error on accept()","myserver");
//perror("accept");
//exit(-1);
continue;
}
LOGD("getb","myserver");
//send at command from ttyGS0

while(1){
//read from ttyGS0
memset(ttyBuf, 0, sizeof(ttyBuf));
ret = read(fd, ttyBuf, BUFSIZE);
if(ret < 0)
{
//printf("Error: read device error!n");
//return 1;
LOGD("Error: read device error","myserver",errno);
}
if(ttyBuf[0] != NULL){

LOGD("while count","myserver",ttyBuf[0]);
LOGD("myserver","yzy is " + ttyBuf[0]);
//strcat(ttyBuf, end);//add /r/n
if(send(new_fd, ttyBuf, strlen(ttyBuf), 0) < 0) {
LOGE("send failed");
}
LOGD("get1","myserver");
#if 1
FD_ZERO(&fds);
FD_SET(new_fd, &fds);
if(new_fd > max)
max = new_fd;
if(select(max + 1, &fds, NULL, NULL, NULL) < 0)//t进行读操作
{
LOGE("select() failed","myserver");
}
if(FD_ISSET(new_fd, &fds)){
if((numbytes = recv(new_fd,buff,sizeof(buff),0))==-1)
{
LOGE("recv failed","myserver");
//perror("recv");
//exit(-1);
}
}
#endif

LOGD("get2","myserver");

if(numbytes > 0){
ret = write(fd, buff, strlen(buff));
if(ret < 0)
{
LOGD("write ttyGS0 error","myserver");
//return 1;
}
}
#endif
}
close(fd);
close(new_fd);
close(fdListen);
#endif
}
return 0;
}
#endif

3.APP端用localSocket来创建client端，用connect()函数来连接native socket server端。
LocalSocket ls = null;
LocalSocketAddress lsa;
ls = new LocalSocket();
lsa = new LocalSocketAddress(SOCKET_NAME,LocalSocketAddress.Namespace.RESERVED);//这里的SOCKET_NAME必须与native和init.rc相同，为sockettest
ls.connect(lsa);
如果socket连上没有问题，就可以收发消息了。

4.小结：native和framework的通信是通过jni，一般情况下是framework调用jni的。如果native有消息，怎么样让framework知道呢？上面使用socket通信，可以让framework和native相互通信。
