Android HTTP POST file upload not working with HttpUrlConnection -

i trying upload file server via http post device. have 2 method upload1 , upload2.

upload1 uses httppost class , works, bigger files throws out of memory exception.

upload2 uses httpurlconnection , not work. (i bad request message server.) want upload2 work, because uses stream send data , throws no out of memory exception. looked @ packages in wireshark, headers seems same, length upload1 380, upload2 94. problem?

private void upload1(file file) {          try {             httpclient httpclient = new defaulthttpclient();             httppost httppost = new httppost(url + "?recname="                     + filename);              // ///////////////////////////////////////             string lineend = "\r\n";             string twohyphens = "--";             string boundary = "---------------------------this boundary";              bytearrayoutputstream baos = new bytearrayoutputstream();             dataoutputstream dos = new dataoutputstream(baos);              fileinputstream fin = new fileinputstream(file);              byte audiodata[] = new byte[(int) file.length()];              fin.read(audiodata);             fin.close();              // send binary file             dos.writebytes(twohyphens + boundary + lineend);              dos.writebytes("content-disposition: form-data; name=\"file\";filename=\""                     + filename + "\"" + lineend);             dos.writebytes("content-type: audio/mp4" + lineend);             dos.writebytes("content-transfer-encoding: binary" + lineend);             dos.writebytes(lineend);             dos.write(audiodata);             dos.writebytes(lineend);             dos.writebytes(twohyphens + boundary + twohyphens + lineend);             dos.flush();             dos.close();              bytearrayinputstream content = new bytearrayinputstream(                     baos.tobytearray());             basichttpentity entity = new basichttpentity();             entity.setcontent(content);              entity.setcontentlength(baos.tobytearray().length);              httppost.addheader("content-type", "multipart/form-data; boundary="                     + boundary);              httppost.setentity(entity);              // //////////////////////////////////              httpresponse response = httpclient.execute(httppost);              bufferedreader reader = new bufferedreader(new inputstreamreader(                     response.getentity().getcontent(), "utf-8"));             stringbuilder builder = new stringbuilder();              (string line = null; (line = reader.readline()) != null;) {                 builder.append(line).append("\n");             }              reader.close();             message = builder.tostring();             system.out.println(message);          } catch (unknownhostexception e) {             message = "error! server unreachable. check internet connection!";         } catch (exception e) {             message = "error: " + e.tostring();         }      }

according problems getting upload files. should use multipart mechanism upload files server.

    httpclient-4.1.jar     httpcore-4.1.jar     httpmime-4.1.jar     apache-mime4j-0.6.1.jar 

for need add couple of libraries project , use http connection , file data.
