Running a Service from ASyncTask or Thread?

Issue

I have an Android app which uses a service to continuously update a textview in the view when the app is open. It updates it using a broadcast receiver which it sends intents to. By the nature of the app, the service needs to continue to run even after the app has exited/the view is gone. Obviously it's not wise to run the service on the main thread in this case, as that will hog up too much and eventually force close and crash the app. So what is the best way to keep this service running? An ASyncTask? A separate thread? How would I go about doing this? I tried it with an ASyncTask like this:

private class MyTask extends AsyncTask {

    @Override
    protected Object doInBackground(Object... objects) {
        return getActivity().getApplicationContext().startService(intent);
    }

    @Override
    protected void onCancelled() {
        getActivity().getApplicationContext().stopService(intent);
        super.onCancelled();
    }
}

Oh yeah, I'm using getActivity().getApplicationContext() because this is inside of a fragment.

So this works fine; I call MyTask.execute() when I want to start it and MyTask.cancel(true) when I want to stop it, but I'm pretty sure I'm not using it how it should be used. I don't even know what I'm supposed to use as the argument for the execute method (??). And it doesn't seem to be the best idea to just start a service in it and nothing else, surely that would work better using just a thread? What's the proper way to go about this, in order for it to work the way it was intended to? By the way, although this does work for much longer than running it on the main thread, it does still crash after several hours.

Solution

Update: I think I figured it out. I was way off in what I thought I needed to do, apparently for the kind of service I had I only needed to run it in the foreground (so using the startForeground() method). It seems to be working now. Sorry!
