body: <p>I'm sending files to amazon s3 server like this and really need to change part sizes of sending file from default amazon (5mb) to 1 mb, is there any way to do that?  </p>
  
  <pre><code> TransferObserver observer = transferUtility.upload(
                              "mydir/test_dir",     /* The bucket to upload to */
                              data.getData().getLastPathSegment(),    /* The key for the uploaded object */
                              root        /* The file where the data to upload exists */
                      );;
  </code></pre>
