Question

Answer 1

On option is to use listeners, where you create an interface that your activity implents, something like:

public interface AsyncListener {
    public void doStuff( MyObject obj );
}

That way, if you're subclassing AsyncTask, it is easy to add this listener, then in onPostExecute(), you could do something like:

protected void onPostExecute( MyObject obj ) {
   asyncListener.doStuff(obj);
}
