Use Handler / AsyncTask or any other Component for file upload
<p>I need to implement the following functionality:</p>

<p>i> Multiple files needs to be uploaded sequentially.</p>

<p>ii> When one file is uploaded successfully , the next file in the list needs to start uploading.   </p>

<p>iii> I need to implement the progressdialog too with the  percentage of the file upload(getting refreshed).</p>

<p>Need hints/suggestions on how to begin the httpcommunication. Should I use Handler since I need to upload multiple files &amp; also handle retry options incase of upload failure? 
I found out AsyncTask normally works for a single task , so is it worth implementing the above functionality using AsyncTask.</p>
