You need to add a view on the public (and private, if needed) download
lists (getPublicDownloadList, getPrivateDownloadList).
If you're just interested on completion, in the onDownloadAdded
callback of the object you provided to addView, you can register a
whenSucceeded callback on the download:
aDownload.whenSucceeded().then(function () { ... });
For other states, you need to handle them in the onDownloadChanged
callback. You should track your own previous state for the changes
you're interested into, if applicable.
Cheers,
Paolo
