I don't know about your code but providing you both working codes: This is for all types of files. I used it for image, audio and for video files.

Android:

new UploadFileAsync().execute("");



  private class UploadFileAsync extends AsyncTask<String, Void, String> {

    @Override
    protected String doInBackground(String... params) {

        try {
  String sourceFileUri = "/mnt/sdcard/abc.png";

            HttpURLConnection conn = null;
            DataOutputStream dos = null;
            String lineEnd = "\r\n";
            String twoHyphens = "--";
            String boundary = "*****";
            int bytesRead, bytesAvailable, bufferSize;
            byte[] buffer;
            int maxBufferSize = 1 * 1024 * 1024;
            File sourceFile = new File(sourceFileUri);

            if (sourceFile.isFile()) {

                try {
                    String upLoadServerUri = "http://website.com/abc.php?";

                    // open a URL connection to the Servlet
                    FileInputStream fileInputStream = new FileInputStream(
                            sourceFile);
                    URL url = new URL(upLoadServerUri);

                    // Open a HTTP connection to the URL
                    conn = (HttpURLConnection) url.openConnection();
                    conn.setDoInput(true); // Allow Inputs
                    conn.setDoOutput(true); // Allow Outputs
                    conn.setUseCaches(false); // Don't use a Cached Copy
                    conn.setRequestMethod("POST");
                    conn.setRequestProperty("Connection", "Keep-Alive");
                    conn.setRequestProperty("ENCTYPE",

                            "multipart/form-data;boundary=" + boundary);
                    conn.setRequestProperty("bill", sourceFileUri);

                    dos = new DataOutputStream(conn.getOutputStream());

                    dos.writeBytes(twoHyphens + boundary + lineEnd);
                    dos.writeBytes("Content-Disposition: form-data; name=\"bill\";filename=\""
                            + sourceFileUri + "\"" + lineEnd);

                    dos.writeBytes(lineEnd);

                        bufferSize = Math
                                .min(bytesAvailable, maxBufferSize);
                        bytesRead = fileInputStream.read(buffer, 0,
                                bufferSize);

                    }

                    // send multipart form data necesssary after file

 <?php

                            $pic_name = $_FILES['bill']['name'];
                            move_uploaded_file($tmp_name, $uploads_dir.$pic_name);
                            }
               else{
                   echo "File not uploaded successfully.";
           }

   ?>
