Android和PC端通过局域网文件同步
本文为大家分享了Android和PC端通过局域网文件同步的具体代码，供大家参考，具体内容如下
publicclassFileOptions{
publicStringname;
publicStringpath;

}

break;
case1:
tvMsg.setText("请在PC端输入IP："+GetIpAddress()+"端口:"+msg.obj.toString());
break;
case2:
Toast.makeText(getApplicationContext(),msg.obj.toString(),Toast.LENGTH_SHORT).show();
break;
}
}
};

((i>>8)&0xFF)+"."+

}
}
//socket管理

PC端用VS2005写的。用了Json格式数据进行数据通信。主要用法为：在同一局域网内，打开PC端和Android端程序，按照Android端提示的IP地址及端口在PC端程序编辑框中正确输入，点击链接，即可将sd卡根目录下的相关文件夹下的文件同步到PC端。
