title: How to download the files in specific folder in internal storage
body: <p>I am trying to create a separate folder in internal storage of a phone for an app to download files on it.  But the folder is not created in the phone. What is the reason? Also I have another issue in my app that is photos are not downloaded when I click thee download button.</p>
  
  <p>Here is the download function</p>
  
  <pre><code>    public void download() {
      for (MediaModel item : Items) {
  
         if (item.isSelected) {
  
              Log.d("check", "download");
              final String url = item.getFullDownloadURL();
              BaseDownloadTask task = FileDownloader.getImpl().create(url);
              task.setListener(mFileDownloadListener)
              .setPath(Environment.getDataDirectory() + "/" + Constants.STORED_FOLDER, true)
                      .setAutoRetryTimes(1)
                      .setCallbackProgressTimes(0)
                      .asInQueueTask()
                      .enqueue();
  
              if (FileDownloader.getImpl().start(mFileDownloadListener, true)) {
                  item.setTaskId(task.getId());
                  item.setStatus(ItemStatus.DOWNLOADING);
                  Logging.e(TAG, "start download task: " + task.getId());
              } else {
                  item.setTaskId(task.getId());
                  item.setStatus(ItemStatus.NORMAL);
                  Logging.e(TAG, "error download task: " + task.getId());
              }
          }
      }
  }
  </code></pre>
