Chromcast远程播放器在使用nanohttpd服务器时寻求在搜索位置0恢复。当我在设备中寻找视频播放器时工作正常，但在电视搜索栏设置为0位置和音乐统计开始时的主要问题。
何时在onSeekChanged（）中调用mRemoteMediaPlayer.seek（）获得结果成功，但在电视搜索栏设置为0位置并开始音乐统计。
public class webserver extends NanoHTTPD {
FileInputStream fileInputStream;
public webserver(){
super(8080);
}
@Override
public Response serve(String uri, Method method, Map<String, String> header,Map<String, String> parameters, Map<String, String> files) {
String mediasend=" ";
long size=0;
FileInputStream fis = null;
try {
fis = new FileInputStream(path);
//byte[] buffer = new byte[(int) fis.getChannel().size()];
size=fis.getChannel().size();
} catch (Exception e) {
e.printStackTrace();
}
switch(mediatype){
case "photo":
mediasend="image/jpeg";
break;
case "audio":
mediasend="audio/mp3";
break;
case "video":
mediasend="video/mp4";
break;
}
return new NanoHTTPD.Response(com.castoffline.castActivity.NanoHTTPD.Response.Status.OK,mediasend,fis,size);
}
}

远程播放器控制代码。
private void sendMediaControl(final boolean playbackPaused,final boolean change)
{
