public class DownloadLaunchRunnable

You can use this to launch downloading, on here the download will be launched separate following steps:

step 1. create the trial connection ( this trial connection is used for: 1. checkup the saved etag is overdue 2. checkup whether the partial-accept is supported 3. checkup whether the current connection is chunked. ) step 2. if the saved etag is overdue -> jump to step 1 to checkup whether the partial-accept is supported. step 3. if (NOT chunked) & partial-accept & output stream support-seek: create multiple DownloadTask to download. else: create single first connection and use FetchDataTask to fetch data from the connection.

We use DownloadStatusCallback to handle all events sync to DB/filesystem and callback to user.
