hhmm ok... So I guess it should be possible for example to make my own class extending AsyncTask and implementing callaback interfaces to it from the aforementioned modules, does that sound feasable/logical at all ? I was wondering though, because its somewhat asynchronous operations how should that be implemented ? Specifically, I know that the method doInBackground will actually do the work, but in my case the work is asynchronous itself... The conneciton module has to be started, then the AsynTask will have to wait for a response from that module telling it it's done downloading, then the AsyncTask should start the parsing, wait till that's done and then finally it can write to the DB... These status callbacks can be implemented through my own interfaces, but other methods would be called and not for example the doInBackground... Am I making my problem any clearer now ? :D
