how to get soundcloud audio download url by using audio file id

I fix it myself, i was using android and the stream url is also a download url. the stream url is also download url for downloading but it won't affect on download count. you can try like that

String file_url = "https://api.soundcloud.com/tracks/93216523/stream?client_id=4346c8125f4f5c40ad666bacd8e96498"; 

pass this url to asyntack and manage you download there, you can pass it like that

new DownloadFileFromURL().execute(file_url);

here is DownloadFileFromUR class using asyntask

class DownloadFileFromURL extends AsyncTask<String, Integer, String> {        @Override        protected void onPreExecute() {            super.onPreExecute();        }        @Override        protected String doInBackground(String... f_url) {            URL u = null;            InputStream is = null;                   try {                          u = new URL(f_url[0]);                          is = u.openStream();                           HttpURLConnection huc = (HttpURLConnection)u.openConnection();//to know the size of video                          int size = huc.getContentLength();                                       if(huc != null){                          String fileName = "FILE2.mp3";                          String storagePath = Environment.getExternalStorageDirectory().toString();                          File f = new File(storagePath,fileName);                          FileOutputStream fos = new FileOutputStream(f);                          byte[] buffer = new byte[1024];                          long total = 0;                          int len1 = 0;                          if(is != null){                             while ((len1 = is.read(buffer)) > 0) {                                 total+=len1;                                 publishProgress((int)((total*100)/size));                                   fos.write(buffer,0, len1);                                }                          }                          if(fos != null){                             fos.close();                          }                      }                                      }catch (MalformedURLException mue) {                        mue.printStackTrace();                 } catch (IOException ioe) {                        ioe.printStackTrace();                } finally {                           try {                                             if(is != null){                               is.close();                             }                           }catch (IOException ioe) {                                 // just going to ignore this one                           }                }                 return "";        }        @Override        protected void onPostExecute(String file_url) {        }    }

DownLoad Class:

  private class DownloadFile extends AsyncTask<String, Integer, String> {    @Override    protected String doInBackground(String... params) {        int count;        try {            URL url = new URL(file_url);            URLConnection conexion = url.openConnection();            conexion.connect();            // this will be useful so that you can show a tipical 0-100% progress bar            int lenghtOfFile = conexion.getContentLength();            // download the file            InputStream input = new BufferedInputStream(url.openStream());            OutputStream output = new FileOutputStream(getOutputMediaFile());            byte data[] = new byte[1024];            long total = 0;            while ((count = input.read(data)) != -1) {                total += count;                           // publishing the progress....                publishProgress((int) (total * 100 / lenghtOfFile));                output.write(data, 0, count);            }            output.flush();            output.close();            input.close();        } catch (Exception e) {        }        return null;    }    @Override    protected void onProgressUpdate(Integer... values) {        super.onProgressUpdate(values);    }    @Override    protected void onPostExecute(String s) {        super.onPostExecute(s);    }}
