Samba（也被称为SMB/CIFS）是一个用于在局域网内共享文件和打印服务的协议，广泛应用于Windows和Linux系统之间的文件共享。
一、展示Samba服务器下的文件
使用如jcifs这样的Java库来在安卓应用中集成SMB/CIFS客户端功能。这个库提供了与SMB/CIFS服务器进行通信的API，允许在安卓应用中直接访问共享文件。
代码实现 :
java
NtlmPasswordAuthentication auth =
new NtlmPasswordAuthentication(SambaManager.getDomainName(path), "zhanghao", "mima");
SmbFile file = new SmbFile("smb://172.16.1.94/", auth);
//根路径 smb://172.16.1.94/
//循环遍历即可 二、尝试使用MediaPlayer播放
代码如下
java
// MediaPlayer.java
String uri = "smb://172.16.1.73/lyg/newtestsamb/._Stay_With_Me 新郎入场.mp3";
mstarPlayer.setDataSource(context, uri);报错文件解析错误，经排查原生的Android MediaPlayer不直接支持通过SMB协议访问和播放文件，因为它主要是为本地存储和网络流媒体设计的。
三、转成HTTP流播放
代码如下
java
public abstract class StreamServer {
// ==================================================
// API parts
// ==================================================
/**
* Override this to customize the server.<p>
* <p>
* (By default, this delegates to serveFile() and allows directory listing.)

* @param method "GET", "POST" etc.
* @param parms Parsed, percent decoded parameters from URI and, in case of POST, data.

}使用代码如下 :
java
//开启指向本地127.0.0.1的服务器
Streamer streamer = Streamer.getInstance();
//设置路径
NtlmPasswordAuthentication auth =
new NtlmPasswordAuthentication(SambaManager.getDomainName(path), "lig", "123456!");
SmbFile file = new SmbFile("smb://172.16.1.73/lig/newtestsamb/jaychou.ogg", auth);
streamer.setStreamSrc(file, null);将http的uri复制给MediaPlayer
java
Uri uri = Uri.parse(Streamer.URL +
Uri.fromFile(new File(
Uri.parse("smb://172.16.1.73/lig/newtestsamb/jaychou.ogg").getPath()))
.getEncodedPath());
mstarPlayer.setDataSource(context, uri);
