android - AsyncTaskLoader doesn't run -


i want implement asynctaskloader in project using compatibility package, followed loader manual in android docs.

the problem loader nothing, seems loadinbackground() never called

any idea of what's wrong in code? (expandablelistfragment extends fragment,but doesn't override critical method )

thank :-)

/**edit:

i realized (late, i'm moron) asynctaskloader abstract class need subclass it... m(__)m leave question in case comes here behind me, knows...

public class agendalistfragment extends expandablelistfragment implements         loadermanager.loadercallbacks<jsonarray> {      private treemap<integer, arraylist<evento>> mitems = new treemap<integer, arraylist<evento>>();     private agendalistadapter madapter;     private progressbar mprogressbar;      @override     public view oncreateview(layoutinflater inflater, viewgroup container,             bundle savedinstancestate) {         view root = inflater.inflate(r.layout.fragment_agenda, container);         mprogressbar = (progressbar) root.findviewbyid(r.id.loading);         return root;      }      @override     public void onactivitycreated(bundle savedinstancestate) {         super.onactivitycreated(savedinstancestate);          madapter = new agendalistadapter(getactivity());         setlistadapter(madapter);          getloadermanager().initloader(0, null, this);      }      @override     public loader<jsonarray> oncreateloader(int arg0, bundle arg1) {         mprogressbar.setvisibility(view.visible);         return new asynctaskloader<jsonarray>(getactivity()) {             @override             public jsonarray loadinbackground() {                  return getdatafromservice(agendaservices.listado_mes);              }          };     }      @override     public void onloadfinished(loader<jsonarray> loader, jsonarray data) {          // stuff turn jsonarray treemap          mprogressbar.setvisibility(view.gone);         madapter.setitems(mitems);      }      @override     public void onloaderreset(loader<jsonarray> arg0) {         madapter.setitems(null);         mprogressbar.setvisibility(view.visible);      }  }

i think best solution compatibility package override asynctaskloader.onstartloading method.

e.g.

@override protected void onstartloading() {   if(dataisready) {     deliverresult(data);   } else {     forceload();   } }
