Android与c语言socket连接,Android 与 native C 利用本地socket进行消息传

Android 与 native C 利用本地socket进行消息传递

Java源码：

// 服务器端

import java.io.BufferedReader;

import java.io.InputStream;

import java.io.InputStreamReader;

import android.net.LocalServerSocket;

import android.net.LocalSocket;

import android.util.Log;

public class SocketListener extends Thread {

@Override

public void run() {

Log.i(getClass().getName(), "run()");

try {

LocalServerSocket server = new LocalServerSocket("com.example.mysoftphone.localsocket");

while (true) {

LocalSocket receiver = server.accept();

Log.i(getClass().getName(), "server.accept()");

if (receiver != null) {

InputStream input = receiver.getInputStream();

InputStreamReader inputReader = new InputStreamReader(input);

BufferedReader bufferReader = new BufferedReader(inputReader);

String line = bufferReader.readLine();

// String line1 = new String(line.getBytes("UTF-8"));

Log.i(getClass().getName(), line);

}

}

} catch (Exception e) {

Log.e(getClass().getName(), e.getMessage());

} finally {

}

}

}

C代码：

// 客户端

#include #include #include #include #include #include #include #define THIS_FILE "ipc_client.c"

int send_remote_request(char *msg, int size)

{

int result;

int len;

int namelen;

int localsocket;

struct sockaddr_un remote;

char *name = "com.example.mysoftphone.localsocket";//与java上层相同哦

localsocket = socket(AF_UNIX, SOCK_STREAM, 0);

if (localsocket == -1)

{

__android_log_print(ANDROID_LOG_ERROR, THIS_FILE, "socket failed!");

return -1;

}

remote.sun_family = AF_UNIX;

remote.sun_path[0] = '\0'; /* abstract namespace */

strcpy(remote.sun_path+1, name);

namelen = strlen(name);

len = 1 + namelen + offsetof(struct sockaddr_un, sun_path);

result = connect(localsocket, (struct sockaddr *)&remote, len);

if (result == -1)

{

__android_log_print(ANDROID_LOG_ERROR, THIS_FILE, "connect failed!");

return -1;

}

result = send(localsocket, msg, size,0);

if (result == -1)

{

__android_log_print(ANDROID_LOG_ERROR, THIS_FILE, "send failed!");

return -1;

}

close(localsocket);

return 0;

}
