It is not a good idea to use AsyncTasks for file downloads (as the name of your AsyncTask suggests). AsyncTasks should not be used for long running operations such as networking. Indeed AsyncTask have two main issues that are related : <ul> <li>they are poorly tied to the activity life cycle</li> <li>the create memory leaks very easily.</li> </ul> Inside the <a href="https://github.com/octo-online/robospice" rel="nofollow">RoboSpice</a> Motivations app (<a href="https://play.google.com/store/apps/details?id=com.octo.android.robospice.motivations" rel="nofollow">available on Google Play</a>) we answer that question in detail. It will give an in-depth view of AsyncTasks, Loaders, their features and drawbacks and also introduce you to an alternative solution for network requests : RoboSpice. We even provided <a href="https://github.com/octo-online/robospice/wiki/Understand-the-basics-of-RoboSpice-in-30-seconds" rel="nofollow">an infographics</a> to explain this issue. To put it in a few words <ul> <li>AsyncTasks are flawed as they are poorly tied to Activity Lifecycle and create memory leaks</li> <li>Loaders are pretty good for what they have been designed for : accessing cursors of Sqlite databases, but don't offer any support for networking. They are the wrong tool for this.</li> <li>RoboSpice executes network requests in a service, your downloads are executed in an Android Service, memory is well managed and it even provides support for writing REST requests.</li> </ul> <hr> I encourage you to download the <a href="https://play.google.com/store/apps/details?id=com.octo.android.robospice.motivations" rel="nofollow">RoboSpice Motivations app</a>, it really explains this in-depth and provides samples and demonstrations of the different ways to do some background operations.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
