title: Is AWS Multipart upload supported for Android?
body: <p>I'm using the Amazon AWS S3 SDK for video and data uploads in Android, and I've got it working fine for 'normal' (i.e., non Multipart) uploads, running in an AsyncTask so as not hold up the UI.</p>
  
  <p>If I allow the user to cancel the upload (for whatever reason), the progress bar disappears, but the AsyncTask seems to hang up until the upload completes.  I've tried killing it with the usual methods, but I think the problem is due to the AWS call continuing with the upload, even though I've tried to kill the AsyncTask.</p>
  
  <p>Having trawled around SO and the AWS forums, what I think I need in order to be able to cancel an in-progress upload, is a MultiPart upload, to allow me to abort the upload AsyncTask between part-uploads.  Trouble is, I can't find any examples of how to do this in Android, or samples of code in the samples-bundle that comes with the AWS SDK (that I can find).</p>
  
  <p>Does anyone know of a tutorial, or a sample project that I can get ideas from, to get a Multipart upload working?  Do I need to use TransferManager to do this?</p>
  
  <p>Many thanks in advance!</p>
