android – wcf渐进式下载

这是我到目前为止所拥有的.这似乎工作,但它不是渐进式下载.它在Android应用程序中播放,但仅在整个文件下载后播放.

服务合约：

[OperationContract,WebGet(UriTemplate = "/GetFileStream/?filepath={virtualPath}")]
    Stream GetFileStream(String virtualPath);

服务配置：

<bindings>
        <webhttpBinding>
            <binding name="streamedhttpBinding" transferMode="StreamedResponse"
                     maxReceivedmessageSize="1000000000">
            </binding>
        </webhttpBinding>
    </bindings>
    <service name="...">
            <endpoint address="" behaviorConfiguration="restful" binding="webhttpBinding"
                bindingConfiguration="streamedhttpBinding"
                contract="..." />

     </service>
     <behaviors>
        <endpointBehaviors>
            <behavior name="restful">
                <webhttp />
            </behavior>
        </endpointBehaviors>
        <serviceBehaviors>
            <behavior name="">
                <serviceMetadata httpGetEnabled="true" />
                <serviceDebug includeExceptionDetailInFaults="true" />
            </behavior>
        </serviceBehaviors>
    </behaviors>

如果您可以提供有关渐进式下载的源的链接,那么这也会有所帮助.对于渐进式下载wcf,我的谷歌搜索没有太多.感谢您的帮助.

Android代码：

player.reset();
player.setAudioStreamType(Au@L_693_12@manager.STREAM_MUSIC);
player.setDatasource(path);
player.prepare();
player.start();

玩家是一个MediaPlayer对象.我正在将数据源设置为路径中的URl.
