To me is diffucult to understand which the right workflow is to download json data and show them in a ListView.
Currently i am using an AsyncTask to download and parse data that is shown using an ArrayAdapter. The problem is that AsyncTask doesn’t survive to activity restarts.

So I am wondering if services are a better solutionbut how to pass data to the ArrayAdapter? Should I always use the db as middle layer to store and retrieve data?

So which is better? AsyncTask in retained fragment or service using db?

Thanks

    I use a service to do http data retrieval and storage into sqlite db. Once the service has stored the data (or if there is a problem) I then fire a broadcast. My Fragments / Activities listen for these defined broadcasts and then act appropriately.

    I find that this is a very clean solution and avoids the problems of leaking asynctask references on activity teardown / rotation etc.
