java - Android/java echo Nest文件上传错误

Question

所以我一直试图弄清楚如何将文件上传到 echoNest 服务器上进行分析，但我无法做到，实际上在 :Track track = echoNest.uploadTrack(file,true); 之后什么也没有发生

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());

我在网上搜索时遇到了类似的问题，但没有找到解决方案。

Answer 1

您的 api key 似乎无效，并且您的 jar 导入相互冲突。您必须确保在 AsyncTask 内进行该调用。之后，一切都会正常进行。
