android 进程间通信之SOCKET通信，androidsocket

java 和C 之间进 行socket通信

java 

//连接服务器

private static finale String SOCKET_NAME = "mySocket";
public boolean connect(){
        if(mSocket!=null)
               return true;
try{

mSocket = new LocalSocket();

LocalSocketAddress address = new LocalSocketAddress(SOCKET_NAME,LocalSocketAddress.Namespace.RESERVED);

mSocket.connect(address);//连接

mIn = mSocket.getInputStream();//输入

mOut = mSocket.getOutputStream();//输出

}catch(IOException ex){

disconnect();

return false;

}

}
