Package com.amazonaws.mobileconnectors.s3.transferutility Description

This package contains helper classes for managing upload and download tasks and a public class s3.transferservice.transferManager which is a high level client that provides methods to control users' upload and download tasks. For starting transfer tasks, here is a sample usage.

 // Initializes TransferUtility
 TransferUtility transferManager = new TransferUtility(s3, getApplicationContext());
 // Starts a download
 TransferObserver observer = transferManager.download("bucket_name", "key", file);
 observer.setTransferListener(new TransferListener() {
     public void onStateChanged(int id, String newState) {
         // Do something in the callback.
     }

     public void onProgressChanged(int id, long bytesCurrent, long bytesTotal) {
         // Do something in the callback.
     }

     public void onError(int id, Exception e) {
         // Do something in the callback.
     }
 });
 

For pausing and resuming tasks:

 // Gets id of the transfer.
 int id = observer.getId();

 // Pauses the transfer.
 transferManager.pause(id);

 // Resumes the transfer.
 transferManager.resume(id);
 

For cancelling and deleting tasks:

 // Cancels the transfer.
 transferManager.cancel(id);

 // Deletes the transfer.
 transferManager.delete(id);
