All you ever wanted to know about Android Loaders and never dared to ask.
Important: I no longer recommend to use a Loader for "one-shot" actions because it's complicated and has a few side-effects. So I recommend to still use AsyncTasks in that case. You can create an AsyncTask inside a Fragment with setRetainInstance(true) to keep the same AsyncTask instance accross configuration changes, but beware not to update the view or interact with the Activity if the result arrives while the fragment is stopped. If you don't need the result, a static AsyncTask will do the job.
Clipping is a handy way to collect important slides you want to go back to later.
