Manage async tasks in fragments: Java Design Patterns and APIs for Android

The abstract class AsyncTask is one of the most popular concurrency tools in Android. It lets you run code in a background thread while still communicating with the user interface. But AsyncTask has a well-known issue: if you declare an AsyncTask object as a member of an Activity, the task can be destroyed along with its parent activity during a configuration change, such as a change in orientation. To prevent this, you can host the asynctask in a fragment object that doesn’t have a user interface. That object can be retained in memory, even during app configuration changes.
