AsyncTaskLoader basic example. (Android)

Question

I am using a Loader in my application and based on the result I get from the query I perform on COntacts using this Loader I perform some calculations and store them back in

Answer 1

Since Honeycomb and the v4 Compatibility Library it is possible to use AsyncTaskLoader. From what I understand, the AsyncTaskLoader can survive through config changes like screen flips. But using AsyncTask you can mess up with configuration changes.

Key information: AsyncTaskLoader is subclass of Loader. This class performs the same function as the AsyncTask, but a bit better, it can also be useful in handling configuration changes (screen orientation).

A very good example and explanation is given here. http://www.javacodegeeks.com/2013/01/android-loaders-versus-asynctask.html

Google has a pretty good example directly in the API Docs. Android Design Patterns provides some more detail and the reasoning behind Loaders.
