所以我一直在试图找出如何在echonest服务器上上传文件进行分析，但是我无法，实际上在：Track track =
echoNest.uploadTrack（file，true）;之后什么也没发生。

String[] args={"/storage/sdcard1/Music/Drive soundtrack/A Real Hero (feat. Electric Youth).mp3"};
            File file = new File(args[0]);

            if(!file.canRead())
            {
                printUsage();
                System.out.println("Insert a valid path!");
            }

            System.out.println("validd path!");
            EchoNestAPI echoNest = new EchoNestAPI("080NXJV4Y....");
            System.out.println("hello!");
            Track track  = echoNest.uploadTrack(file,true);

            System.out.println("uploaded!");
            track.waitForAnalysis((60*1000)/2);


            System.out.println("ID: "+track.getID());
            System.out.println("Artist: "+track.getArtistName());
            System.out.println("Title: "+track.getTitle());

在Internet上搜索时遇到了类似的问题，但找不到解决方案。
