NanoTasks is an extremely light way to execute code in the background on Android. It is a wrapper arround AsyncTask that provides a simpler to use and more flexible API.

• NanoTasks is meant to be extremely simple to use and leightweight. If you are looking for more features please have a look to RxJava or Bolt.
• The onSuccess/onError callbacks won't be called if your context is null. No more NPE crashes because the Activity was destroyed (Although as some people pointed out this is not totally solved yet. I'm working on a better solution for the v2).

Tasks.executeInBackground(context, new BackgroundWork<Data>() {
    @Override
    public Data doInBackground() throws Exception {
        return fetchData(); // expensive operation
    }
}, new Completion<Data>() {
    @Override
    public void onSuccess(Context context, Data result) {
        display(result);
    }
    @Override
    public void onError(Context context, Exception e) {
        showError(e);
    }
});
