安卓:来自局域网的媒体播放器流

Question

我有一个经典的服务器-客户端tcp套接字系统，用于将消息从客户端发送到服务器。这很好用。现在我正在尝试播放声音遥控器。客户端应该发送声音的路径。它是/mnt/sdcard/Music/sound.mp3这是它发送给服务器的内容。

服务器知道客户端IP。也许IP字符串看起来像/192.168.1.2服务器应该对其进行解释，并通过流式传输启动声音。

private void playSound (String soundFileName) {
        Uri myUri1 = Uri.parse("file:/" + _clientIP + soundFileName);
        _txtHint.setText(myUri1.toString());
        mPlayer = new MediaPlayer();
        mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
        try {
            mPlayer.setDataSource(getApplicationContext(), myUri1);
        } catch (IllegalArgumentException e) {
            Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
        } catch (SecurityException e) {
            Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
        } catch (IllegalStateException e) {
            Toast.makeText(getApplicationContext(), "You might not set the URI correctly!", Toast.LENGTH_LONG).show();
        } catch (IOException e) {
            e.printStackTrace();
        }
        try {
            mPlayer.prepare();
        } catch (IllegalStateException e) {
            Toast.makeText(getApplicationContext(), "MISE: You might not set the URI correctly!", Toast.LENGTH_LONG).show();
        } catch (IOException e) {
            Toast.makeText(getApplicationContext(), "MIOE: You might not set the URI correctly!", Toast.LENGTH_LONG).show();
        }
        mPlayer.start();
    }

如果我采用一个简单的http URI，它运行得非常好（即。http://test.com/sound.mp3)。将播放声音。现在我正在尝试播放客户端发送到服务器的声音。但是代码在mPlayer.prepare();处出现IOException（"Prepared failed:status 0x1"），我认为URI是错误的。我尝试了几种方法（rtsp://IP:port/path、rtsp://IP/path，与file://和http://相同）。但我找不到合适的。也许我错过了什么？服务器是否有访问客户端声音的权限？如果没有，如何将其提供给服务器？

谢谢你的帮助！贪婪，S-Man

第1版：ServerSocket

try {       
     _serverSocket = new ServerSocket(SocketServerPORT);
            while (true) {
                socket = _serverSocket.accept();
                dataInputStream = new DataInputStream(
                        socket.getInputStream());
                dataOutputStream = new DataOutputStream(
                        socket.getOutputStream());
                _message = dataInputStream.readUTF();
                _clientIP = socket.getInetAddress().toString();
                Server.this.runOnUiThread(new Runnable() {
                    @Override
                    public void run() {     
                        //Here the Sound should be played.
                        Server.this.playSound(_message);
                    }
                });
                dataOutputStream.writeUTF(_message);
      }
} catch (IOException e) {...

尝试通过MXPlayer播放链接（请参阅上下文菜单->网络流）以检查其是否正确。
