Using fragments is an OK solution, but AsyncTask is grossly overused in most android applications. Instead, use an IntentService or a Loader, depending on the circumstance.

IntentServices+Loaders are superior to AsyncTasks in a few important ways:

1. AsyncTasks are bound to the process of their activity. Non-foreground activities are considered to be cached, meaning they can be killed at any time. If you care about your asynchronous task completing regardless of the activity’s state, use an IntentService. POSTs are a good example.

2. For instances where you don’t care about the result of an AsyncTask if the activity is destroyed, you still shouldn’t use them – Loaders do a much better job of cancelling requests and managing resources, and are more concise. Downloading and showing images from a web service is a good example.

Is just what I needed for my project.
