java - File is not getting uploaded to server -

i uploading audio file android application server.upload code running on side not file not getting upload on server.here code m using .i have commented code file getting uploaded .here code :

public void uploadfile(string path, string id) {      httpurlconnection connection = null;     dataoutputstream outputstream = null;       string pathtoourfile = "" + path;      string urlserver = "http://txtapi.com/musicapp/uploadfile.php?fileid=" + id + "&sharedby=" + sp.getstring(commonutility.phone, commonutility.getphonenumber(ct));     string lineend = "\r\n";     string twohyphens = "--";     string boundary = "*****";     int bytesread, bytesavailable, buffersize;     byte[] buffer;      try {         fileinputstream fileinputstream = new fileinputstream(new file(pathtoourfile));          url url = new url(urlserver);         connection = (httpurlconnection) url.openconnection();         // allow inputs & outputs         connection.setdoinput(true);         connection.setdooutput(true);         connection.setusecaches(false);         // enable post method         connection.setrequestmethod("post");         connection.setrequestproperty("connection", "keep-alive");         connection.setrequestproperty("content-type", "multipart/form-data;boundary=" + boundary);         outputstream = new dataoutputstream(connection.getoutputstream());         outputstream.writebytes(twohyphens + boundary + lineend);         outputstream.writebytes("content-disposition: form-data; name=\"fileid\";filename=\"" + path + "\"" + lineend);         outputstream.writebytes(lineend);         bytesavailable = fileinputstream.available();         // read file         //              bytesread = fileinputstream.read(buffer, 0, buffersize);//file getting upload code          //              int  =0;         //              while (bytesread > 0)         //              {         //              i++;         //                   //              outputstream.write(buffer, 0, buffersize);                                     //              bytesavailable = fileinputstream.available();         //              buffersize = math.min(bytesavailable, maxbuffersize);         //              bytesread = fileinputstream.read(buffer, 0, buffersize);         //              }          buffer = new byte[1024];          int bufferlength = 0;          while ((bufferlength = fileinputstream.read(buffer)) > 0) {             //add data in buffer file in file output stream (the file on sd card             log.i("bytes available ", "" + fileinputstream.available());             log.i("buffer length", "" + bufferlength);              outputstream.write(buffer);             //add size know how downloaded          }         outputstream.writebytes(lineend);         outputstream.writebytes(twohyphens + boundary + twohyphens + lineend);         // responses server (code , message)         fileinputstream.close();         outputstream.flush();         outputstream.close();      } catch (exception ex) {           ex.printstacktrace();         bugsensehandler.setlogging(true);         //exception handling         log.i("inside catch of  ", "inside catch of upload ");         bugsensehandler.sendexception(ex);     } {         system.gc();     }  } 

the amount of bytes read should amount of bytes written outputstream change following:

    while ((bufferlength = fileinputstream.read(buffer)) > 0) {         //add data in buffer file in file output stream (the file on sd card         log.i("bytes available ", "" + fileinputstream.available());         log.i("buffer length", "" + bufferlength);          outputstream.write(buffer, 0, bufferlength);         //add size know how downloaded      }
