asynctaskloader

I want to implement an AsyncTaskLoader in my project using the Compatibility Package, so I followed the Loader manual in Android Docs. The problem is that the Loader does nothing, it seems loadInBackground() is never called Any idea of what's wrong in my code? ( ExpandableListFragment extends Fragment ,but doesn't override any critical method ) Thank you :-) /**EDIT: I realized (late, I'm a moron) that AsyncTaskLoader is an abstract class so I need to subclass it... m(__)m I leave the question in case someone comes here behind me, who knows... public class AgendaListFragment extends

When using a AsyncTaskLoader how would you update a progressbar showing the status as it is being updated? Normally you wait for the callback to remove when done, but how to do running updates? Would you let the main thread (ui) poll the data as it is being set or something? Edit: I'm talking about AsyncTaskLoader , look at the loader part. Here is link to class: http://developer.android.com/reference/android/content/AsyncTaskLoader.html I want to use it because its the future :), I know how to do this with AsyncTask. You can do that with loaders, but you need to keep and update a

I considered some examples of working with AsyncTaskLoader and Fragment ( https://gist.github.com/codeswimmer/884591 ) and I tried to do the same. But now I can't fix incompatible types error - in method onCreateLoader. I have no idea why it happens, because I have done the same. FeedLoader.java public class FeedLoader extends AsyncTaskLoader<ArrayList<RSSItemData>> { ArrayList<RSSItemData> listData; Context ctx; RSSItemData rssItem; final Integer HTTP_CONNECTION_TIMEOUT = 15; DBHelper dbHelper; public FeedLoader(Context context) { super(context); this.ctx = context; dbHelper = new DBHelper

Currently I am using an asynchronous http library to execute http requests against our server. However this carries the problem where if an http call is in progress during a screen rotation we will have a reference to the old context when the call finishes. I sort of got around this by keeping a static reference to the latest instance captured in onCreate and would call methods with that reference (and null it out in onDestroy). It worked ok but seemed like a hack. I've seen some people recommend the use of fragments to deal with this, like here: http://www.androiddesignpatterns.com/2013/04

I have been reading Android documentation ( AsyncTask , Thread ) and vogella tutorial about this matter, but I have doubts yet. For example, I want to send a message from an Android app to a server. And I would like this process to be responsive. What should I use? I have seen examples where they create a new Thread for not block UI, but this way we don't have the progress of process, also you have to process the response within the Thread because the run() method doesn't returning anything. AsyncTask seems better option than Thread , but I don't know what are the consequences of using an
