Android local socket学习总结

##############################################

目的：实现本地 C程序与apk的socket通信。

原理：没有涉及到网络通信，所以使用Android封装的local socket要更简单

参考：系统源码RIL模块

C程序服务端：

1) server_fd = socket_local_server (SOCKET_NAME_XXH,

ANDROID_SOCKET_NAMESPACE_ABSTRACT, SOCK_STREAM);

2) s_fdListen = listen(server_fd, 4);

3) while((socket = accept(server_fd, NULL, NULL)) > 0)

C 客户端：

1) fd = socket_local_client( SOCKET_NAME_XXH ,

ANDROID_SOCKET_NAMESPACE_ABSTRACT, SOCK_STREAM);

2) write(fd, "hello", 5);

JAVA 客户端：

1) localSocket = new LocalSocket();

2) localSocket.connect(new LocalSocketAddress(socketAddress));

3) OutputStream os = localSocket.getOutputStream();

Namespace:

LocalSocketAddress.Namespace ABSTRACT A socket in the Linux abstract namespace

LocalSocketAddress.Namespace FILESYSTEM A socket named with a normal filesystem path.

LocalSocketAddress.Namespace RESERVED A socket in the Android reserved namespace in /dev/socket.
